In biology, the term "gravid" ( "burdened, heavy"Oxford English Dictionary) is used to describe the condition of an animal (most commonly fish or reptiles) when carrying eggs internally. For example, Astatotilapia burtoni females can transform between reproductive states, one of which is gravid, and the other non-gravid. In entomology it describes a mated female insect.

Also, the anterior ovary in A. australiensis females extends anteriorly to about the mid-length of the oesophagus, while it does not reach the end of the oesophagus in A. novaezelandiae.

The number of proglottids released per day may vary from 0 to 35. Cysticercus grows into adult in about 2.5 to 4 months, by the time gravid proglottids are found in faeces.

Abortion may also be performed surgically by hysterotomy or gravid hysterectomy. Hysterotomy abortion is a procedure similar to a caesarean section and is performed under general anesthesia. It requires a smaller incision than a caesarean section and can be used during later stages of pregnancy. Gravid hysterectomy refers to removal of the whole uterus while still containing the pregnancy.

Megameres develop into a syncytial layer, the outer embryonic membrane; mesomeres into the radially striated inner embryonic membrane or embryophore; micromeres become the morula. The morula transforms into a six-hooked embryo known as an oncosphere, or hexacanth ("six hooked") larva. A gravid proglottid can contain more than 50,000 embryonated eggs. Gravid proglottids often rupture in the intestine, liberating the oncospheres in faeces.

The cichlid males' behavior of shifting between dominant and subordinate states as a result of the social environment can also be related to females in their vicinity, for females may alternate between reproductive states as well, but independently of social conditions. Females use a complex integration of cues in order to make their mate preferences, which may be from genetic factors, learned behaviors, or hormone levels. They can socially transform between a gravid reproductive state, which is egg- bearing, and a non-gravid reproductive state, and it was shown in a study that the mating preferences of the female highly depended on the reproductive state in which the female was in. Gravid female cichlids will prefer to spend time with the dominant male type instead of the subordinate male type, whereas the non-gravid females do not have a preference for either one.

A gravid female adult will first locate suitable habitats, and then identify patches of vegetation that contain potential host plants. The cabbage butterflies seem to limit their search to open areas and avoid cool, shaded woodlands even when host plants are available in these areas. Furthermore, gravid females will not oviposit during overcast or rainy weather. In laboratory conditions, high light intensity is required to promote oviposition.

Only the male frogs are able to produce mating calls to attract gravid female frogs. When male and non-gravid female frogs are clasped by sexually active male frogs, they produce a release call. In the leopard frog, there are three movements for their sound production. First, there are body wall contradictions to serve as a way for the intra-pulmonary pressure to increase.

The definitive host within this life cycle is primarily canines, and occasionally felines, and in rare cases young children. The intermediate hosts include fleas (Ctenocephalides spp.) and chewing lice. The first stage in the life cycle is when the gravid proglottids are either passed out through fecal matter, or actively crawl out of the anus of the host. The gravid proglottids once out of the definitive host release eggs.

Echinococcus shiquicus is a parasitic worm first identified in 2006. It was found in Tibetan foxes in the Qinghai–Tibet plateau region. Two types of adult worms were recovered and the variant which had a short strobila consisting of single immature and single gravid segments constituted the majority of the specimens. The strobila, rostellar hooks, location of the genital pore and the number of eggs in gravid uterus helped in differentiating Echinococcus shiquicus from the other species.

Guppies are highly prolific livebearers giving birth to between five and 30 fry, though under extreme circumstances, she may give birth to only one or two or over 100. The gestation period of a guppy is typically 21–30 days, but can vary considerably. The area where a pregnant guppy's abdomen meets the tail is sometimes called the "gravid patch", or "gravid spot". When pregnant, there is a slight discoloration that slowly darkens as the guppy progresses through pregnancy.

After the worm has time to develop and grow in size, the gravid proglottids is released from the distal end of the parasite and passed in the feces to start a new cycle.

The reproductive season lasts from March to September, and one to three breeding waves may be observed. Females are gravid for 4–5 weeks before releasing 4–18 mancae from the brood pouch.

Alternatively, females were seen to have an increase in body condition around the same time, which is thought to support embryo development. Gravid female snakes have also been observed to be basking more frequently compared to males and non-gravid females, as it is thought the warmth facilitates the growth of the embryos. Giant garter snakes are ovoviviparous, meaning they carry eggs internally but give live birth. Following the spring mating season, birthing occurs from mid July to early October with average litter size of 17 young.

Intact gravid proglottids are shed off in groups of four or five. The free eggs and detached proglottids are spread through the host's defecation (peristalsis). Oncospheres can survive in the environment for up to two months.

After they are free swimming, they can be fed a finely powdered fish food or infusoria. Spawning activity could include: flaring of the fins on males, a gravid spot on females, or males reluctantly chasing females.

Fecal flotation may reveal eggs if a gravid proglottid has been broken in the feces. After the animal dies, a necropsy is performed to see if cysticerci are found in the abdominal cavity of sheep and goats.

The minimum total length for a gravid female is about . It seems that sexual maturity is achieved in 2–3 years. In one case, it took a specimen nearly 4.5 hours to give birth to 11 young.

Newly emerged and mated females inject a neurotoxin-containing saliva into their hosts, which paralyzes the host and enables the gravid female mites to feed on the host's hemolymph. The posterior portion (opisthosoma) of the female enlarges as its progeny develops inside, and, within a few days, up to 250 adult mites emerge from the gravid female. Bruce and Wrensch (1990) found that progeny of the straw itch mite averaged 254 offspring of which 92% were females. Males emerge before the females, position themselves around the mother's genital opening, and mate with emerging females.

If the host was gravid any eggs laid may be eaten by the wasp larva as well as the host herself. Prey species are known to come from a number of genera of spiders including Trite and Clubiona.

Gravid females on average will hold 60 eggs, but have been observed with 120 eggs. Hatchling range from 5.0 to 5.1 mm. E. tippecanoe may also be a fractional spawner and could possible generate more eggs during the year.

They often select natural orifices or wet fur, though they do not tend to oviposit in wounds, as is mistakenly thought by many. Gravid L. sericata prefer warm temperatures for their offspring, since this will decrease development time and therefore increase survival, and they will oviposit faster and with more eggs in warmer carrion. Egg load peaks at 30 degrees C. Research also suggests that sulfur compounds and indole are the major factors attracting gravid flies to carrion, raising the possibility that these compounds could be used to attract flies to traps in order to control them in agricultural settings.

The estimations of the number of eggs in a gravid female pinworm range from about 11,000 to 16,000. The egg-laying process begins about five weeks after initial ingestion of pinworm eggs by the human host. The gravid female pinworms migrate through the colon towards the rectum at a rate of 12 to 14 cm per hour. They emerge from the anus, and while moving on the skin near the anus, the female pinworms deposit eggs either through (1) contracting and expelling the eggs, (2) dying and then disintegrating, or (3) bodily rupture due to the host scratching the worm.

Gravid females were also observed from September to May except April, and number were highest in January and February. Females show multiple oviposition. Each egg pod may contain 20-30 eggs and first instars are observed in late December or early January.

Breeding takes place during the first heavy rains of the wet season. Gravid females have been found in bromeliads. The eggs are laid on dry land. This species possesses "direct development", the eggs develop directly into tiny juvenile frogs, skipping a tadpole stage.

Thick-tailed geckos lay up to 2 eggs and up to 10 clutches per year. The first clutch of eggs is usually infertile. When the female is gravid the eggs are visible through the skin. The eggs take about 65 days to hatch.

Taeniasis is contracted after eating undercooked pork or beef that contain the larvae. The adult worms develop and live in the lumen of the intestine. They acquire nutrients from the intestine. The gravid proglottids, body segments containing fertilised eggs, are released in the faeces.

News 24 (1/3): 3-4. photographed a gravid female excavating a hole in the forest soil and laying a clutch. One egg was exhumed and found to contain a fully developed embryo. After 35 days, the eggs hatched and the tiny juveniles dispersed.

This gravid proglottid contains the fertilized eggs, which are sometimes expelled with the feces. However, most of the time, the egg may also settle in the microvilli of the small intestine, hatch, and the larvae can develop to sexual maturity without ever leaving the host.

Echinococcus granulosus, also called the hydatid worm, hyper tape-worm or dog tapeworm, is a cyclophyllid cestode that dwells in the small intestine of canids as an adult, but which has important intermediate hosts such as livestock and humans, where it causes cystic echinococcosis, also known as hydatid disease. The adult tapeworm ranges in length from 3 mm to 6 mm and has three proglottids ("segments") when intact—an immature proglottid, mature proglottid and a gravid proglottid. The average number of eggs per gravid proglottid is 823. Like all cyclophyllideans, E. granulosus has four suckers on its scolex ("head"), and E. granulosus also has a rostellum with hooks.

There are usually 2–3 prolonged red surrounded by blue areas on the neck. Color of these areas serves as a "pregnancy indicator". In gravid females red coloration turns bluish-grey and areas become blue. Belly is white with bright orange wash in the rare (abdominal) part.

Like other Nerodia species, the diamondback water snake is ovoviviparous. Adults breed in the spring, and gravid females give birth in the late summer or early fall. Neonates are around in length. Though its range overlaps with several other species of water snakes, interbreeding is not known.

The body surface is smooth; however, males larger than about SVL have dermal spines that in extreme cases cover the entire body. only gravid females have dermal spines in the pericloacal region. Two females, both measuring SVL, contained 590 and 1190 ovarian eggs measuring in diameter.

Ecology of this species is poorly known. The specimen from the Ramba Village (a gravid female) was collected from leaf litter in secondary forest at above sea level. Threats to Phrynobatrachus ogoensis are not known. It is quite possible that it occurs the Lopé National Park.

Females of A. unicolor found roughly during the male breeding season have no offspring and only a few are gravid, where as A. microunicolor found in their breeding season have 90-150 offspring scattered in their burrows. They feed on the multiple varied invertebrates available to them.

Taenia hydatigena (thin-necked bladderworm, causative agent of cysticercosis) is one of the adult forms of the canine and feline tapeworm. This infection has a worldwide geographic distribution. Humans with taeniasis can infect other humans or animal intermediate hosts by eggs and gravid proglottids passed in the feces.

Raillietina require two different hosts for a complete life cycle. The definitive hosts are mostly wild and domestic birds, and sometimes humans. The intermediate hosts are insects, such as ants and beetles. Mature eggs are released from the avian host through feaces by detaching the last gravid proglottid.

The black swamp snake is ovoviviparous, giving birth to live young directly in shallow water. Unlike many snakes, females feed actively while gravid, suggesting that they may pass nutrients directly on to the young. Broods of 11 to 13 have been observed.Schmidt, Karl P.; Davis, D. Dwight (1941).

Unlike in other Taenia, gravid proglottids are shed individually. In some cases, the proglottid ruptures inside the intestine, and the eggs are released. The free proglottids and liberated eggs are removed by peristalsis into the environment. On the ground, the proglottids are motile and shed eggs as they move.

Gravid females release their eggs into the water over bare rocks or gravel at the same time males release their sperm. Fertilization occurs externally. The eggs are adhesive and stick to the rocky substrate. The young are swept downstream after hatching and grow to adulthood in deep freshwater pools.

The breeding season in Aoti, northern Taiwan, is from November to March. The smallest mature male measured SVL and smallest gravid female SVL. Both sexes appear to reach this size by the end of their first year. Peak breeding occurred in December but is probably influenced by rain.

Females develop orange bars along the underside when gravid. Collared lizards have small pockets at the base of the tail and folds of skin above the front legs. Mites and chiggers gather in these areas. C. reticulatus lacks the postfemoral mite pockets present in the rest of the genus.

In birds, the gravid proglottids containing a large number of egg capsules are passed out to the exterior with the feces. The eggs grow on soil into larvae called onchospheres, which are ingested by ants, and enters the alimentary canal, from where they migrates into the abdominal cavity of the host.

It inhabits lakes, reservoirs and ponds, as well as grassy paddies, where it clings to aquatic plants. Each gravid female carries more than 60 embryos inside her. The shell of embryo has three whorls. The pollutant removal in constructed wetlands with these snails was better, that in constructed wetland without them.

Atheris squamigera requires a very high level of humidity to breed. In one case, males and females were kept separate from January to the end of November. Two females became gravid (with one observed mating). Each produced eight young: a smaller percentage were yellow (possible recessive gene), most being green.

Gravid females carrying about 80 eggs have been found between March and July. It is most threatened by the fungal infectious disease chytridiomycosis which causes dramatic decline and affects other species of its genus. Other threats include habitat loss through agriculture (both crops and livestock), logging, planned mining and wood plantations.

N. reganius is an estuarine species, usually found in turbid waters with low salinity, or in fresh water. It is a planktivore. Relative to its size, it is highly fecund (347–1071 eggs per female), and the ovaries of gravid females made up 44% of their total body weight, on average.

Batasio, like most other bagrids, are easy to sex. The male has a visible genital papilla just fore of the anal fin. Gravid female B. tengana (South East Asian form) are easy to identify because the pink eggs can be seen through their semi- transparent belly when they swim near light.

Adult worms can live about 25 years in the host. Usually, only a single worm is present at time, but multiple worms are also reported. In each mature proglottid, self-fertilisation produces zygotes, which divide and differentiate into embryonated eggs called oncospheres. With thousands of oncospheres, the oldest gravid proglottids detach.

The adult stage consists of a scolex with four suckers and an armed rostellum, a short neck region, a series of immature proglottids with undeveloped reproductive organs, a series of mature proglottids with fully developed male and female reproductive organs, and a series of gravid proglottids with an expanded uterus filled with eggs.

Gravidity of adult females lasts the entire year. The average number of newborn snails in the wild is 0.24 snails per day (50 per year) or up to 0.55 snails per day in the laboratory. Each gravid female carries 19–21 embryos inside her. Generation time is quite short at about four months.

Gerrids generally lay their eggs on submerged rocks or vegetation using a gelatinous substance as a glue. Gravid females carry between two and twenty eggs. The eggs are creamy white or translucent, but become bright orange. Gerrids go through the egg stage, five instar stages of nymphal forms, and then the adult stage.

It has a snout-to-vent length of . Juveniles of this species have cobalt blue legs and tails. The entire ventral surface of males, including the tail, may be orange, although gravid females may also have some orange especially lining the lower jaw. The colors are most distinct in the breeding season.

These eggs are eventually released from the gravid proglottid either through a pore in the proglottid or by disintegration of the proglottid. Cestodes also have sensory organs in the scolex that detect tactile stimulation. The sensory organs are attached to longitudinal nerves that run along the body and are attached to organs.

In the wild mating has been seen in February, and a female caught in April was likely gravid. The 2–12 (average 8) oval eggs measure about long and have a leathery white shell. They are deposited on land. In captivity the eggs hatch after about three months at a temperature of .

The soup is named for the "she-crab", or female crab, originally a gravid (roe-carrying) crab, as the orange crab roe comprise a chief ingredient in traditional she-crab soup. As with turtle soup, other ingredients may be added to the soup or substituted for others, although crabmeat is found in all versions.

The lifecycle of coenurosis goes something like this: Eggs and gravid proglottids are shed in feces into the environment by infected definitive hosts (canids). Many animals may serve as intermediate hosts, including rodents, rabbits, cattle, sheep, goats and humans. These intermediate hosts ingest the eggs. Once ingested, the eggs hatch in the intestine, releasing oncospheres.

The gravid female does not fight much, but is often kept for the roe. The current world record is listed by the IGFA as , set at Holyoke Dam, Massachusetts, on 19 May 1986 by Robert A. Thibodo.World Record Game Fishes Publication of the IGFA. American shad exhibit complex and little-understood feeding behavior while spawning.

In the wild, the species is known only from the Nile River basin. The species is harvested for human consumption. In its natural environment, it prefers deep water and rocky habitats. The reproductive habits of most of the species of Synodontis are not known, beyond some instances of obtaining egg counts from gravid females.

Ovoviviparous, females give birth to up to 12 young at a time, each about 15 inches (38 cm) in length. When females become gravid, their skin color darkens. This adaptation provides increased heat absorption for the developing young. After giving birth, the color returns to normal as soon as it next sheds its skin.

Males are cited as possessing a pinkish or reddish hue to the caudal fin during the breeding season (Walker, p. 98) whilst females lack this colour. Otherwise, visual differences between the sexes are far from obvious, and the principal reliable differentiating characteristic is the notably more rounded and fuller-bodied profile of gravid females.

The lesser chameleon lives in a dry arboreal habitat, fragmented by grasslands. Generally it leads a solitary lifestyle, often aggressive towards other members of its own species. They hunt opportunistically. Unlike most chameleons, the female is the more colourful sex, gravid females are adorned with alternating greenish-black and yellow bands and yellow speckling highlighting darker areas.

The ones found in the liver form these bladders that are specifically called Cysticercus pisiformis for T. pisiformis. These signs can only be seen when a necropsy is done to the rabbit. When looking for an infection in dogs there is a more straightforward method. There will be gravid proglottids with striated eggs seen in the feces.

Historically, American paddlefish did not spawn every year because the precise environmental events occurred just once every 4 or 5 years. American paddlefish are broadcast spawners, also referred to as mass spawners or synchronous spawners. Gravid females release their eggs into the water over bare rocks or gravel at the same time males release their sperm. Fertilization occurs externally.

A sick Meller's chameleon may be mottled with brown, gray, pink, or white. A gravid animal is black, cream, and gray colored and will be bulging with eggs. With great care, T. melleri is one of the few species that can be housed in groups. This doesn't always work as some individuals will not get along.

Spawning starts in February in the northern part of its range, and in March farther south. A female will mate with multiple males and can store sperm, yielding broods of eggs that have multiple fathers. Like other fish of its genus, this species is viviparous. The gravid female expels her whole brood at once, only during the night.

Acropyga is a genus of small formicine ants. Some species can be indirect pests. A. acutiventris, which is found from India to Australia, tends subterranean, root-feeding mealybugs of the species Xenococcus annandalei. Living, gravid females are carried in the jaws of A. acutiventris queens during their nuptial flight, to establish the symbiotic association in founding colonies.

The reproductive habits of most of the species of Synodontis are not known, beyond some instances of obtaining egg counts from gravid females. Spawning likely occurs during the flooding season between July and October, and pairs swim in unison during spawning. The growth rate is rapid in the first year, then slows down as the fish age.

In the wild, the species is widespread throughout central Africa. The species is harvested for human consumption. The reproductive habits of most of the species of Synodontis are not known, beyond some instances of obtaining egg counts from gravid females. Spawning likely occurs during the flooding season between July and October, and pairs swim in unison during spawning.

The amniotic fluid is the protective liquid contained by the amniotic sac of a gravid amniote. This fluid serves as a cushion for the growing fetus, but also serves to facilitate the exchange of nutrients, water, and biochemical products between mother and fetus. For humans, the amniotic fluid is commonly called water or waters (Latin liquor amnii).

Ethology of the bee Exomalopsis nitens and its cleptoparasite (Hymenoptera: Anthophoridae). Journal of the New York Entomological Society 94(4) 480-88. Both E. globosa and E. similis have been noted nesting in dirt roads made of gritty red clay. The gravid female piles food in a terminal cell and then molds it into a neat loaf.

In the light phase the opposite is true with the dominant color consisting of gray, pinkish, brown or yellowish brown hues. During the mating season females develop reddish orange spots and bars on their sides and underneath the tail when gravid. Males develop pink or rusty wash on the throat, chest, and sometimes the body, during the breeding season.

In 1764, he became physician to Queen Charlotte. He was elected a Fellow of the Royal Society in 1767 and Professor of Anatomy to the Royal Academy in 1768.

The reproductive habits of most of the species of Synodontis are not known, beyond some instances of obtaining egg counts from gravid females. Spawning likely occurs during the flooding season between July and October, and pairs swim in unison during spawning. The growth rate is rapid in the first year, then slows down as the fish age.

Juvenile snakes and gravid females remain in the rocks and move to cooler, shaded areas. Their habitat has been degraded by urbanization, illegal rock removal, vandalisation and indiscriminate reptile collecting. The sandstone rocks that the snakes occupy are valued for landscaping purposes. Their removal has led to a loss of habitat for both the snakes and their prey.

Reproduction in E. tribuloides seems to be sensitive to seasonal cycles, solar cycles, and the lunar cycle. In the Florida Keys, E. tribuloides was found to obtain peak gravidity in the late summer and early fall. Populations in Panama, however, were found to be gravid in the spring, summer and fall, with peak gravidity occurring around the full moon.

After mating, the gravid female creates a burrow where they bring pollen. On top of the pollen, one egg is laid. This is consumed by the larva over 10 days, after which the larva overwinters and pupates in the next year. Many melittids (such as Macropis) possess specialized morphology that allow them to collect floral oil.

Longitarsus jacobaeae is a species of flea beetle known as the tansy ragwort flea beetle. It is used as an agent of biological pest control against the nectar-rich noxious weed known as ragwort (Senecio jacobaea). The adult beetle is light golden brown in color and between and long. The female is larger than the male, especially when gravid.

"Descriptions of skate egg cases (Chondrichthyes: Rajiformes: Rajoidei) from the eastern North Pacific". Zootaxa 1393: 1-18. Studies have been done where egg cases were removed from gravid females to ensure proper identification in regard to skate species. Egg cases have distinguishable characteristic traits that are unique to that species, thus making it a great tool for identifying a skate.

Sexually mature smooth green snakes mate in the late spring or summer, and gravid females lay eggs from June to September. Usually, two clutches are laid, each containing four to six eggs. Females usually lay their eggs in rodent burrows, mounds of rotting vegetation, sawdust piles, or rotting logs. In the northern habitats of this species, communal nesting has been observed.

Echinococcus adult worms develop from protoscolices and are typically 6 mm or less in length and have a scolex, neck and typically three proglottids, one of which is immature, another of which is mature and the third of which is gravid (or containing eggs). The scolex of the adult worm contains four suckers and a rostellum that has about 25–50 hooks.

The complete life cycle requires two hosts, ruminants as definitive hosts, and oribatid mites as intermediate hosts. Eggs are passed out from the intestine of the ruminant host along the gravid proglottids in the feces into the soil. The eggs are eaten by soil mites. Eggs must reach the gut of mite hosts within 1 day of release otherwise they are desiccated.

The first recorded case of gigantomastia, diagnosed in a 23- or 24-year-old woman, circa 1670. In 1670, the physician Durston drew this illustration of first recorded case of non-gravid gigantomastia; the woman died of the condition. One early and extreme case study of gigantomastia dates to 1670. The patient died four months after the onset of enlargement.

Its habitat is threatened by dam building and water depletion for irrigation. The reproductive habits of most of the species of Synodontis are not known, beyond some instances of obtaining egg counts from gravid females.

The first proglottid stage is the immature stage, characterized by functional reproductive organs. The immature stage is the most anterior proglottid, and consists of anywhere between 200 and 300 proglottids. The mature proglottid is located medially to the other proglottids, and is reproductively functional and hermaphroditic. The most posterior proglottid is the gravid stage, and it is packed with eggs.

Spawning likely occurs during the flooding season between July and October, and pairs swim in unison during spawning.

Landing appears to be mediated primarily by visual cues, of which color is the most important. P. rapae in a lab environment showed no significant preference for the shape or size of the oviposition substrate. Gravid females responded most positively to green and blue/green colors for oviposition. The preference was shown for surfaces with maximal reflectance of 550 nm.

The rest of the body proper, the strobila, is basically a chain of numerous body segments called proglottids. The neck is the shortest part of the body, and consists of immature proglottids. The midstrobila is made of mature proglottids that eventually lead to the gravid proglottids, which are at the posterior end. An individual can have as many as 1000 to 2000 proglottids.

The male and female pinworms mate in the ileum (last part of the small intestine), whereafter the male pinworms usually die,Garcia 1999, p. 246 and are passed out with stool. The gravid female pinworms settle in the ileum, caecum (beginning of the large intestine), appendix and ascending colon, where they attach themselves to the mucosa and ingest colonic contents.

Adult L. sericata feeding on nectar The larvae of L. sericata feed exclusively on dead organic tissue; as the eggs are laid directly into carrion, they are able to feed on the corpse they hatch into until they are ready to pupate. The adults are more varied in their diets, eating carrion and feces as well as pollen and nectar, meaning that they are important pollinators in their native range as well as important agents of decomposition. The pollen (which the flies are capable of digesting, perhaps with the assistance of bacteria in their digestive tracts) may be used as an alternative protein source, especially for gravid females who need large amounts of protein and cannot reliably find carrion. Notably, gravid flies are particularly attracted to sapromyophilous flowers that exude a carrion-like odor, such as the dead horse arum lily.

A pelagic species most commonly encountered along the coast, the Bombay sea snake likely travels via currents over long distances. Typically found in areas with soft substrate, such as sand or mud. Little is known of the mating habits of this snake- based on the single recorded gravid female, they are viviparous. The brood size was 3-4, and the young measured 12 inches long near birth.

There are more than 700 proglottids in the strobila, but less than 1000 (~900), while T. saginata in comparison have more than 1000 proglottids. The proglottids are distinguishable into mature and gravid proglottids. Each mature proglottid contains a complete set of both male and female reproductive systems; hence it is hermaphrodite. Similar to T. saginata the uterus has 13 lateral branches in T. asiatica.

The queen of Lestrimelitta limao will mate with multiple males. While there is one gravid queen, there are typically two or three virgin queens within a colony. The queen has longer and more robust legs than the workers or the males as well as a more developed malar space. While their wings are similar is shape and structure to workers, queen wings contain four to five hamuli.

Lesser earless lizards grow to about 2.0-2.5 in (50–65 mm) snout-to-vent length, plus a tail of 3-4 in (75–100 mm). They are typically grey or tan in color, with black blotching. The males usually have blue patches on either side of their bellies, whereas the females do not. Females often change to have bright orange patches when gravid.

In Myanmar, Leptobrachium rakhinense occurs in primary evergreen rain forest on low-lying mountains at elevations of above sea level. The holotype was found on the forest floor. Males have been observed calling from the ground in leaf litter in September, in the end of the monsoon season, and females collected at the same time were gravid. Natural enemies of this frog include Scolopendra centipedes.

This bug is elongated in shape with an M-shaped mark at the wing-cover bases. The female is about 7 millimeters long and the male is about 6 millimeters. The adult can fly, but each flight is just a jump of a few meters at most, and the gravid female tends not to fly. The adult and juvenile produce a noxious scent when disturbed.

Diagnosis is done by analysis stool sample in which eggs can be detected, or often observation of the gravid proglottids in feces and anus. Niclosamide is most often used. Praziquantel (while not approved for use in ruminants in the US) is also 99–100% effective while albendazole is 19-75% effective; and praziquantel + levamisole combination is very effective in reducing worm burden and improvement of weight.

In the wild, the species has only been found in the Dja River and its tributary, the Libi River in the Central Congo River basin. Its habitat is threatened by cobalt mining on the Dja river. The species is harvested for human consumption. The reproductive habits of most of the species of Synodontis are not known, beyond some instances of obtaining egg counts from gravid females.

In the wild, the species occurs in running and standing waters in the upper Nile basin. It is harvested for human consumption. As a whole, species of Synodontis are omnivores, consuming insect larvae, algae, gastropods, bivalves, sponges, crustaceans, and the eggs of other fishes. The reproductive habits of most of the species of Synodontis are not known, beyond some instances of obtaining egg counts from gravid females.

In the wild, the species has only been found in the Cross and lower Niger Rivers. It lives in streams and lakes and eats plankton, detritus, and plants. It is capable of breathing air, and can live in waters with low dissolved oxygen. The reproductive habits of most of the species of Synodontis are not known, beyond some instances of obtaining egg counts from gravid females.

No eggs of the species have ever been collected from the wild, but examination of collected specimens of gravid females puts the estimated fecundity at 70,000 to 80,000 eggs per individual. Upon hatching, the paralarvae gradually float or swim towards shallower waters. The paralarvae differ from adults in having stouter barrel-shaped bodies with a blunt posterior end. The fins are very small and unfused.

One gravid captive female reached a mass of about , making it one of the heaviest insects in the world and heavier than a sparrow. This is, however, abnormal, as this individual was unmated and retained an abnormal number of eggs. The largest species of giant wētā is the Little Barrier Island giant wētā, also known as the wētāpunga. One example reported in 2011 weighed .

The basic diagnosis is done from a stool sample. Feces are examined to find parasite eggs. The eggs look like other eggs from the family Taeniidae, so it is only possible to identify the eggs to the family, not to the species level. Since it is difficult to diagnose using eggs alone, looking at the scolex or the gravid proglottids can help identify it as Taenia saginata.

The breeding cycle of these frogs is affected by extrinsic environmental conditions and intrinsic reproductive hormonal mechanisms. During the active breeding phase mature gravid females clearly show the presence of large creamy eggs. Nesting occurs terrestrially, mostly underneath rotting logs, and crevices within coconut tree bark and within bamboo. This species lays around 50-60 eggs inside prepared nests and covered with leaf litter.

The ova in female specimens are pigmented and about 1 mm in diameter. Gravid females have been collected from the months of May until late July and implied that they may spawn in early August. E. aloysii co-occurs with other congeners such as E. hexadactylus; E. cyanophlyctis and E. karaavali. Other species include Hoplobatrachus tigerinus, Microhyla ornata, Minervarya sahyadris, Minervarya caperata and, Indosylvirana intermedia.

Egg of T. solium Diagnosis of taeniasis is mainly using stool sample, particularly by identifying the eggs. However, this has limitation at the species level because tapeworms basically have similar eggs. Examination of the scolex or the gravid proglottids can resolve the exact species. But body segments are not often available, therefore, laborious histological observation of the uterine branches and PCR detection of ribosomal 5.8S gene are sometimes necessary.

An accompanying music video for "Duduke" was released on April 19, 2020 and was directed by Adasa Cookey. In the video shot by the beach, the artist showed her baby bump revealing that she is pregnant. The video which was released to coincide with Simi's birthday showed her playing a piano in front of the beach shoreline while also cradling her gravid belly in a silky and flowing yellow gown.

He then creates a tunnel through the more or less spherical nest by swimming vigorously through it. Nest building typically takes 5–6 hours though it may also be spread out over several days. After this, the male courts gravid females that pass by with a zigzag dance. He approaches a female by swimming very short distances left and right, and then swims back to the nest in the same way.

This is a very large nematode, the male about 4 to 6 centimeters long and the female known to exceed 20 centimeters.Mermis nigrescens. Nematology. University of Nebraska, Lincoln. The size is unusual for entomopathogenic nematodes, which are generally almost microscopic. The body is pale brown, and the gravid female has a dark stripe down the length of its body due to the presence of up to 14,000 eggs.

An adult worm resides in the small intestine of a definitive host. Gravid proglottids release eggs that are passed in the feces of the definitive host. The egg is then ingested by an intermediate host. The egg then hatches in the small intestine of the intermediate host and releases an oncosphere that penetrates the intestinal wall and moves through the circulatory system into different organs, in particular the liver and lungs.

This spermatheca is connected to the oocytes by one canal. Each gravid individual will produce from the mucus that it secretes abundantly a transparent cocoon in which are released the fertilized oocytes. Embryos, whose number varies and can reach twenty, develop synchronously. In the laboratory and depending on the rearing conditions, after 4 to 5 days, the juveniles hatch, escape from the cocoon and begin their quest for the photosynthetic partner.

In the wild, the species is known throughout the Congo River basin, with the exception of the southern tributaries. The species is harvested for the aquarium trade. The reproductive habits of most of the species of Synodontis are not known, beyond some instances of obtaining egg counts from gravid females. Spawning likely occurs during the flooding season between July and October, and pairs swim in unison during spawning.

The reproductive habits of most of the species of Synodontis are not known, beyond some instances of obtaining egg counts from gravid females. Spawning likely occurs during the flooding season between July and October, and pairs swim in unison during spawning.

It completes its life cycle in two different hosts. The adult life is spent in the intestine of fowl, which is the definitive host, and juvenile period is in ant, particularly the species of Tetramorium, which is the intermediate host. Gravid proglottids containing a large number of egg capsules are passed out to the exterior with the feces of infested chicken. Each egg capsule in turn contains 3 to 8 eggs.

In the wild, the species has been found in Lake Victoria and the Victoria Nile basin, including smaller tributaries and lakes. It has also been found in the Malagarasi River. It is found in shallow waters of lakes and rivers, most often around of depth. The reproductive habits of most of the species of Synodontis are not known, beyond some instances of obtaining egg counts from gravid females.

Isthmohyla rivularis is a rare species of frog in the family Hylidae. It occurs in the cordilleras of Tilarán, Central, and Talamanca in Costa Rica as well as adjacent western Panama. The species was thought to already have become extinct, but in 2007, it was re-discovered in the Monteverde Cloud Forest of Costa Rica when a single male was found. In 2008, a gravid female and few males were spotted.

In 1768 he built the famous anatomy theatre and museum in Great Windmill Street, Soho, where the best British anatomists and surgeons of the period were trained. His greatest work was Anatomia uteri umani gravidi [The anatomy of the human gravid uterus exhibited in figures] (1774), with plates engraved by Rymsdyk (1730–90),Thornton, John L. 1982. Jan van Rymsdyk: medical artist of the eighteenth century. Oleander Press, Cambridge .

Genital pores are unilateral, and each mature segment contains three testes. After apolysis, gravid segments disintegrate, releasing eggs, which measure 30 to 47 µm in diameter. The oncosphere is covered with a thin, hyaline, outer membrane and an inner, thick membrane with polar thickenings that bear several filaments. The heavy embryophores that give taeniid eggs their characteristic striated appearance are lacking in this and the other families of tapeworms infecting humans.

Its skeletal, muscular and neural anatomy more closely resembles that of forward-walking species, rather than that of more closely related sideways-walking species. L. emarginata will mate in large aggregations. These aggregations may function as a protective mechanism during reproduction. Males of L. emarginata show an unusual "obstetrical behavior", in which gravid females who are about to release their larvae are held behind the male and aggressively protected.

The Savannah monitor is readily available in the pet trade. Juvenile animals are collected from several countries in West Africa (mainly Ghana, Togo, Benin and Nigeria) and exported worldwide. Animals sold as "captive bred", captive farmed or ranched are the offspring of gravid females collected during the breeding season whose eggs are incubated by exporters. Adult specimens frequently become unwanted pets and are reported as being the most common monitor lizards by animal rescue agencies.

The giant African snail is native to East Africa, and can be traced back to Kenya and Tanzania. It is a highly invasive species, and colonies can be formed from a single gravid individual. In many places, release into the wild is illegal. Nonetheless, the species has established itself in some temperate climates and its habitat now includes most regions of the humid tropics, including many Pacific islands, southern and eastern Asia, and the Caribbean.

Eggs are introduced into the environment through infected canine feces. In the feces are the gravid proglottids that house the T. pisiformis eggs that will eventually be released form the proglottid onto nearby vegetation. The eggs are then ingested by a rabbit or from any member of the Leporidae family. Once inside the rabbit's gut the larva or oncosphere phase will then penetrate into the intestinal wall until they reach the blood stream.

According to a Manipuri folklore, a legendary hero Kadeng Thangjahanba of Moirang once captured a gravid sangai from Torbung Lamjao for a gift to his beloved Tonu Laijinglembi during an animal hunting expedition. However, as fate would have it, he found his beloved married to the king on his return. The heartbroken hero released the deer free in the wild of Keibul Lamjao. From that time onwards the place became the home of sangai.

The lethal ovitrap is filled with water and the velour paper landing strip and a pesticide-treated strip from the white packet are attached to the trap. The female mosquito lands on the velour strip to lay eggs and receives a lethal dose of pesticide. A lethal ovitrap is a device which attracts gravid female container-breeding mosquitoes and kills them. The traps halt the insect's life cycle by killing adult insects and stopping reproduction.

Like all Cyclophyllidea, Bertiella has a scolex, suckers, and many segments called proglottids. These are released into the body from the adult tapeworm, contain both male and female anatomical structures, and are in stages of mature, postmature and gravid. In general, human Bertiella morphology is not well understood due to the rarity of infection, and therefore limited possibility for study and observation. Particularly lacking are descriptions of adult stages of the species.

Females were gravid in spring and summer. Asaccus zagrosicus is distinguished from other similar species by a combination of the following: secondary postmental scales not in contact with the lowerlabials; scansors not extending beyond the claws, body size may be greater than in length. This species of Asaccus feeds on small insects including larva. It was observed as active at night and during the day, only inside of tunnels in the Tang-e-Haft region.

Secreted mucus is also an interface (biofilm) between the animal and its environment. Specific bacterial populations develop and appear to be hosted in the mucus, being hence intimately involved in the worm biology. On the left a gravid S. Roscoffensis adult: the white double string are mature oocytes that will be rapidly fertilized. Each pregnant adult deposits the fertilized oocytes in a translucent cocoon in which between 10 and 20 embryos develop.

In the wild, the species is known from Pool Malebo, and has been recorded in the Kasai River basin and the Kwango River Basin. The fish is caught for human consumption.

In the wild, the species is known from only one location in Nigeria in the lower Niger River. The species is harvested for human consumption. The primary threats to the species arise from pollution in its habitat and the small area of habitat, and it is listed as an endangered species. The reproductive habits of most of the species of Synodontis are not known, beyond some instances of obtaining egg counts from gravid females.

The definitive hosts for these Taenia species are canids. The adult tapeworms live in the intestines of animals like dogs, foxes, and coyotes. Intermediate hosts such as rabbits, goats, sheep, horses, cattle and sometimes humans get the disease by inadvertently ingesting tapeworm eggs (gravid proglottids) that have been passed in the feces of an infected canid. This can happen from ingesting food, water or soil that has been contaminated by dog feces.

Here he gained his habilitation in 1853 with a thesis involving retroverted gravid uterus (De retroversione uteri gravidi). In 1858 he was an associate professor of obstetrics at the University of Marburg, and during the following year accepted an appointment as a gynecologist at the University of Munich. At Munich he was also director of the municipal district maternity hospital and school for midwives. In 1874/75 he served as university rector.

In the wild, the species occurs in the Luapula-Mweru system of the upper Congo River basin. The species faces threats from overfishing, although the species has a broad distribution. As a whole, species of Synodontis are omnivores, consuming insect larvae, algae, gastropods, bivalves, sponges, crustaceans, and the eggs of other fishes. The reproductive habits of most of the species of Synodontis are not known, beyond some instances of obtaining egg counts from gravid females.

Westralunio carteri generally has separate sexes (males and females), but hermaphrodites occur occasionally. Gametes (sperm in males or eggs in females) develop in the gonads and, with the onset of spawning, eggs migrate from the female gonads (ovaries) into specialised areas of the gills known as 'marsupia'. At this stage, females are 'gravid'. Fertilised eggs of Westralunio carteri (and other species of Hyriidae) are brooded to become embryos, which develop into larvae, known as 'glochidia'.

Male (top) female (bottom) Miomantis caffra mating. The abdomen of the female is visibly bulging as she is gravid from a prior mating encounter. Adults of M. caffra are usually 32–60 mm long, pale green or brown, occasionally with pink or purplish colouration near base of fore-wing; hind wings are green or bright yellow. Pronotum narrower than head, approximately 1/3 of body length, rounded dorsally and swollen over the leg attachment.

These catfish species are small and transparent. The three species can be distinguished by differences in body shape, coloration, and the degree of serrations on the anterior edge of the pectoral fin spine. The three species range from about 3-4.4 centimetres (1.2-1.7 in) SL. Hyalobagrus species are sexually dimorphic, males possess a genital papilla, and gravid females are easy to spot since their blue-green eggs are visible through their bellies.

Schindleria brevipinguis is a species of marine fish in family Gobiidae of Perciformes. Known as the stout infantfish, it is native to Australia's Great Barrier Reef and to Osprey Reef in the Coral Sea. S. brevipinguis is among the smallest known fish in the world, together with species such as Paedocypris progenetica. Males of S. brevipinguis have an average standard length of , a gravid female was and the maximum standard length of the species is .

Violet carpenter bees hibernate overwinter and they emerge in the spring, usually around April or May. Hibernation is undertaken by the adults in wood where there are abandoned nest tunnels. In the late spring or early summer, they may be seen around searching for mates and suitable nesting sites. After mating, the gravid females bore tunnels in dead wood, which is where the name "carpenter bee" comes from, although old nest tunnels may be used.

It is diurnal and probably solitary. It forages on the ground and in the understory and is seldom seen in the canopy, more often on the trunk and lower branches according to Jones Jr. & Genoways in 1971. The breeding season is long, from at least February to September, and litters of mostly 3, sometimes 2, young were been reported by Jones Jr. & Genoways based on 6 gravid females. Jones Jr. & Genoways reported that it may moult twice a year.

The upside-down pipefish (Heraldia nocturna) is a species of pipefish endemic to the coast of southern Australia, from New South Wales to Geographe Bay in Western Australia, where it is found in rocky reefs at depths of from . It grows to a length of SL. This species is the only known member of its genus. Like other pipefish it is ovoviviparous but it may breed seasonally, as gravid males have been collected between September and November.

E. vogeli has the largest strobila within the Echinococcus genus, reaching a length of 12 mm. This tapeworm resides in the small intestine of bush and domestic dogs. E. vogeli contains a scolox, where a hook-filled rostellum is located, and a long neck that attaches to up to six proglottids. The gravid proglottid, the sexually mature proglottid that releases eggs into the dogs feces, is cylindrical and takes up about half of the strobilar length.

Good crop hygiene is one cultural control used to minimize Delia infestations, particularly D. antiqua and D. radicum. Studies have shown that damaged or crushed onion bulbs left behind after harvest were major sources of D. antiqua food and an overwintering site. Damaged plants release volatile chemicals that attract gravid females while the wounds on the plants provide easy access to newly emerged larvae. As such, removing waste crop material from harvested fields is recommended to decrease overwintering populations.

During the 1920s opinion shifted to the idea that plesiosaurs swam with a rowing motion. However, a paper published in 1975 that once more found support for sea turtle-like swimming in plesiosaurs. This conclusion reignited the controversy regarding plesiosaur locomotion through the late 20th century. In 2011, F. Robin O'Keefe and Luis M. Chiappe concluded the debate on plesiosaur reproduction, reporting the discovery of a gravid female plesiosaur with a single large embryo preserved inside her.

He utters long strings of grunts and growls while fighting, but his courtship call is more of a prolonged hum. He may produce this sound for over an hour at a time, reaching frequencies near 100 Hz. When a male makes the sound, gravid females respond by moving toward him. The fish produces the sound using the muscles of its modified swim bladder. It receives the sound in its saccule, a sensory organ in the inner ear.

In the wild, the species has been found in the middle Zambezi River basin, as well as the Pungwe River and Buzi River. It inhabits rivers and floodplains, favoring floodplains, but does not occur in rocky areas. The reproductive habits of most of the species of Synodontis are not known, beyond some instances of obtaining egg counts from gravid females. Spawning likely occurs during the flooding season between July and October, and pairs swim in unison during spawning.

In the wild, the species has been found in rivers and the swampy areas of lakes, in Lake Rukwa and the Rufigi basin of Tanzania. It inhabits the areas close to shore. The reproductive habits of most of the species of Synodontis are not known, beyond some instances of obtaining egg counts from gravid females. Spawning is thought to happen in April or May, in the open water of the lake, and pairs swim in unison during spawning.

Organisms found in and around sponge reefs include annelid worms, bryozoans, spider crab, King crab, shrimp, prawns, and euphausids. Echinoderms, especially sea urchins and sea stars, were abundant in areas of the reef where the sponges were dying or deceased, and can be used as an indicator of sponge reef health. Rockfish, especially Sebastes species, live in openings and in between sponges. Gravid and juvenile rockfish were observed, suggesting that the reefs are being used as a nursery area.

The reproductive habits of most of the species of Synodontis are not known, beyond some instances of obtaining egg counts from gravid females. Spawning likely occurs during the flooding season between July and October, and pairs swim in unison during spawning. The fish feeds on detritus and plant matter such as seeds, as well as small invertebrates like insects and snails. The growth rate is rapid in the first year, then slows down as the fish age.

A gravid female adult will lay disproportionate number of eggs on peripheral or isolated plants. A single larva is less likely to exhaust the whole plant, therefore laying eggs singly prevents the likelihood of larval starvation from resource exhaustion. This behavior may have evolved to exploit the original vegetation in the eastern Mediterranean where brassica plants originated. Age of butterflies appears to have no effect on their ability to select the source of highest concentration of oviposition stimulant.

Linnet also has two adopted Rumanian-born children, Peter and Maria. She is a Bisexual and has had both male and female lovers, and has, over time, become a Lesbian icon in Denmark. On 6 June 2010, BT reported that Anne Linnet had signed a partnership and awaited children with 23-year-old Tessa Franck.Anne Linnet gift med gravid 23-årig – BT.dk On 31 July 2010, Tessa Franck Linnet gave birth to a daughter named Isolde Elisabeth Franck Linnet.

The adult worm is about long. Gravid proglottids containing the worm's microscopic eggs are either passed in the definitive host's feces or may leave their host spontaneously and are then ingested by microscopic flea larvae (the intermediate hosts) in the surrounding environment. As in all members of family Dipylidiidae, proglottids of the adult worm have genital pores on both sides (hence the name double-pore tapeworm). Each side has a set of male and female reproductive organs.

A captive juvenile king cobra in its defensive posture The female is gravid for 50 to 59 days. The king cobra is the only snake that builds a nest using dry leaf litter, starting from late March to late May. Most nests are located at the base of trees, are up to high in the center and wide at the base. They consist of several layers and have mostly one chamber, into which the female lays eggs.

The naupliar and copepodid stages until they locate a host are nonfeeding and live on endogenous food stores. Once attached to the host, the copepodid stage begins feeding and begins to develop into the first chalimus stage. Copepods and chalimus stages have a developed gastrointestinal tract and feed on host mucus and tissues within range of their attachment. Preadult and adult sea lice, especially gravid females, are aggressive feeders, in some cases feeding on blood in addition to tissue and mucus.

Ovulating and gravid females are rarely ever caught, suggesting that during this period, they may stop feeding or segregate themselves from others of their species. Potential predators of the night shark include larger sharks. Known parasites include the copepods Kroyeria caseyi, which attach to the gills, Pandarus bicolor and P. smithii, which infest the skin, and the tapeworms Heteronybelinia yamagutii, H. nipponica and Progrillotia dollfusi, which are found in the spiral valve intestine. Another parasite is an undescribed isopod similar to Aega webbii.

If a dragon's rider dies, the dragon immediately suicides by going between without a destination. The only exception is when the rider of a queen dragon dies while the queen is gravid; the dragon waits just long enough to lay her eggs and see them hatch before disappearing between. (Humans who lose their dragons typically commit suicide as well. However, some do survive, although the experience leaves profound psychological trauma.) Ping also designed the dragons to be fairly calm in temperament.

The cysticercus, the larval form, travels and persists in the liver for 18 – 30 days, then burrows out into the peritoneal cavity and attaches to the viscera. When the sheep viscera is scavenged and the scavenger ingests the cysticercus, the protoscolex attaches to the small intestinal wall and the worm begins to form proglottids. Gravid proglottids, containing the eggs, move from the end of the worm and leave the body in the feces. The prepatent period is about 51 days.

A resuscitative hysterotomy, also known as a peri-mortem caesarean delivery, is an emergency caesarean delivery carried out where maternal cardiac arrest has occurred, to assist in resuscitation of the mother by removing the aortocaval compression generated by the gravid uterus. Unlike other forms of caesarean section, the welfare of the fetus is a secondary priority only, and the procedure may be performed even prior to the limit of fetal viability if it is judged to be of benefit to the mother.

In the wild, the species has been found in the upper Zambezi River basin, and the Okavango River system. The reproductive habits of most of the species of Synodontis are not known, beyond some instances of obtaining egg counts from gravid females.

In the wild, the only a few specimens have been collected from a very limited geographic area around Bonge, Cameroon. The reproductive habits of most of the species of Synodontis are not known, beyond some instances of obtaining egg counts from gravid females. Spawning likely occurs during the flooding season between July and October, and pairs swim in unison during spawning. As a whole, species of Synodontis are omnivores, consuming insect larvae, algae, gastropods, bivalves, sponges, crustaceans, and the eggs of other fishes.

In the wild, the species has been found in the basins of the Nile River and Shabeele River, and Turkana Lake, Albert Lake, Edward Lake, and Kyoga Lake. The reproductive habits of most of the species of Synodontis are not known, beyond some instances of obtaining egg counts from gravid females. Spawning likely occurs during the flooding season between July and October, and pairs swim in unison during spawning. The fish feeds on algae, macrophytes, detritus, crustaceans, insects and mollusks.

Following birth, the neonates mass together in their natal burrow. Most often, gravid females select an east-facing, small-diameter rodent burrow for giving birth. For the first week or so of their lives, neonatal sidewinders literally plug the entrance to this burrow during daylight hours, forming a dynamic multiple- individual mass that takes advantage of the hot exterior environment and the cool interior of the burrow to maintain an average aggregate temperature of 32 °C (the optimal temperature for shedding).

In the wild, the species is endemic to Lake Tanganyika, which has a temperature range of , and an approximate pH of 8.5 – 9, and dH range of 4-15. It inhabits rocky shorelines in the littoral zone, to a maximum depth of . The reproductive habits of most of the species of Synodontis are not known, beyond some instances of obtaining egg counts from gravid females. Spawning likely occurs during the flooding season between July and October, and pairs swim in unison during spawning.

Previous islands now beneath the sea (guyots) form the Emperor Seamount Chain. All of the native Drosophila and Scaptomyza species in Hawaii have apparently descended from a single ancestral species that colonized the islands, probably 20 million years ago. The subsequent adaptive radiation was spurred by a lack of competition and a wide variety of niches. Although it would be possible for a single gravid female to colonise an island, it is more likely to have been a group from the same species.

In captivity, however, the fish sometimes stops swimming upside down and its color pattern reverses, so that it is dark on the back and light on the underside. In the wild, it feeds on plankton, detritus, insects, crustaceans, and mollusks. The reproductive habits of most of the species of Synodontis are not known, beyond some instances of obtaining egg counts from gravid females. Spawning likely occurs during the flooding season between July and October, and pairs swim in unison during spawning.

Diplodactylus conspicillatus are oviparous meaning they lay eggs as opposed to giving birth to live young. They breed from September to February and November to March in more northern areas. Little is known about their mating behaviour; however, it is thought cloacal spurs are most likely used to grasp the female during copulation. Gravid females exhibit a marked increase in girth before laying their eggs in shallow scapes of moist sand or on the sand surface beneath fallen trees and other vegetation.

What has been discovered is that spawning appears to vary with latitude with gravid females being collected during the late spring and early summer in Delaware while further south, in North Carolina and Georgia spawning takes place during the early fall and late winter. They have a maximum life span of 8 years and sexual maturity is attained at one year old. Their diet is made up largely of invertebrates including amphipods, decapods, and beetles with some smaller fishes and Odonata.

American crocodiles breed in late fall or early winter, engaging in drawn-out mating ceremonies in which males emit low- frequency bellows to attract females. Body size is more important than age in determining reproductive capabilities, and females reach sexual maturity at a length of about . In February or March, gravid females will begin to create nests of sand, mud, and dead vegetation along the water's edge. Nest location is crucial, and with the correct amount of vegetation, the eggs will develop within a small temperature range.

The cysticercoid stage develops either outside the body in an insect that can then be eaten by a human or a rat, or it develops in the intestinal villus of an auto-infected human. The adult phase begins with the growth of the scolex with several hooks. After attaching itself to the intestinal wall and growing proglottids, fertilized eggs can pass in the host’s stool as the gravid proglottids deteriorate and release eggs. [3] H. diminuta fertilized eggs pass in the stool from an infected host.

For the duration of the eggs' development, the male will chase away other males and nongravid females. He may, however, court other gravid females (more than one batch of eggs can be deposited in the same nest). The sequence of territorial courtship and mating behaviours was described in detail by Niko Tinbergen in a landmark early study in ethology. Tinbergen showed that the red colour on the throat of the territorial male acts as a simple sign stimulus, releasing aggression in other males and attracting females.

The gravid females have been collected from a variety of habitat including debris filled ditches with soft bottoms as well as gravel bottomed streams and heavily vegetated sand and gravel pits. They will spawn in a variety of water conditions ranging from free-flowing clear or turbid water through stagnant water in ditches and pools. Fliers creat nests in rocks or gravel and surround their eggs with a round adhesive egg envelope. They are colonial nesters, nesting in aggregations with the nests quite closely spaced.

Most common are studies of proglottids passed in stool samples of infected hosts. Studies have shown that specimens collected from humans are essentially morphologically the same as specimens collected from monkey hosts, except for some anatomical differences in reproductive organs. However, these discrepancies in morphological findings have led researchers to postulate that there may be more than two human Bertiella species, as previously believed. These gravid proglottids in stool are white and can measure around 11 mm for maximum length and 8 mm for maximum width.

In the wild, the species has been found in the White Nile river from Khartoum into the Baḥr al-Jabal River and Bahr el Ghazal River systems, and the Baro River in Ethiopia. The reproductive habits of most of the species of Synodontis are not known, beyond some instances of obtaining egg counts from gravid females. Spawning likely occurs during the flooding season between July and October, and pairs swim in unison during spawning. The fish feeds on algae, macrophytes, detritus, crustaceans, insects and mollusks.

The adult, gravid female holotype had a snout-to-vent length of with a slender body across, and an elongated snouth. The tail was broken but regenerated, longer than the body, with smooth dorsal caudal scales and two strongly keeled scales on the sides of each annulus. The precloacal area was covered with enlarged, elongated scales arranged in a single arch-shaped row, presumably carrying precloacal pores in males. The iris of P. ziaiei is yellow and grey with the pupillary slit outlined in yellow.

Rakitov R.A. (2004) Powdering of egg nests with brochosomes and related sexual dimorphism in leafhoppers (Insecta, Hemiptera, Cicadellidae). Zoological Journal of the Linnean Society 140: 353-381. In gravid females from these genera, the Malpighian tubules switch over from production of regular brochosomes, described above, to production of larger, typically elongate particles, up to 20 micrometres in length. Prior to laying eggs, the female places masses of such brochosomes onto its forewings, and later scrapes them off onto the freshly laid eggs with its hindlegs.

Like the other members of the family Cancridae, the slender crab has a very broad and oval carapace with dull, tooth-like protrusions toward the front of the carapace. Female crabs can be distinguished from males by a broad tail flap on their undersides, which are used for protecting their eggs when they are gravid. The slender crab carapace is usually olive brown, and its legs vary from yellowish brown to purple. M. gracilis only grows to a width of about and resembles a juvenile M. magister.

Nautiluses reproduce by laying eggs. Gravid females attach the fertilized eggs, either singly or in small batches, to rocks in warmer waters (21-25 Celsius), whereupon the eggs take eight to twelve months to develop until the juveniles hatch. Females spawn once per year and regenerate their gonads, making nautiluses the only cephalopods to present iteroparity or polycyclic spawning. Nautiluses are sexually dimorphic, in that males have four tentacles modified into an organ, called the "spadix", which transfers sperm into the female's mantle during mating.

When a gravid proglottid that is distended with an embryo reaches the end of the strobila, it detaches and passes out of the host intact with feces, with or without some tissue degeneration. In the order Pseudophyllidea, the uterus has a pore and the proglottid sheds the shelled embryo, only becoming detached when exhausted. Some members of the Eucestoda (such as Echinococcus, Sparganum, Taenia multiceps sp., and Mesocestoides sp.) can reproduce asexually through budding, which initiates a metagenesis of alternating sexually and asexually reproducing generations.

When they emerge from their sheltesr at night they have been found to use vocalisations, popping, to maintain social contactwithin a shoal. They perceive sounds through a specialisation of the swim bladder, Baudelot's ligament and their lateral line. Gravid females have been collected from mid November up until February and spawning has been observed to occur at the same timeo with the juveniles settling from January to April. The juveniles have been recorded from weed growing along rock shorelines in the late (Austral) summer.

Fecundity is usually related to size of the fish, so it isn't unusual for the roe of a large gravid female to contain over 55,000 eggs. Bowfin eggs are adhesive, and will attach to aquatic vegetation, roots, gravel, and sand. After hatching, larval bowfin do not swim actively in search of food. During the seven to nine days required for yolk-sac absorption, they attach to vegetation by means of an adhesive organ on their snout, and remain protected by the parent male bowfin.

Host grubs are hidden in the soil, so mother flies cannot predict where they will be and lay her eggs in exactly the right spot. Instead, gravid flies lay their eggs at the optimal height on tall plants or wire fences in their meadow habitats. At around 1.25 to 1.5 meters off the ground, the larvae will gain the greatest benefit from the wind helping them to disperse. This results in the maximum number of offspring finding a host, with the minimum number of offspring being forced to share a host.

The eastern green mamba is solitary, except during breeding season. Gravid females tend to be sedentary, but males actively search out and court prospective mates during the rainy season—between April and June. Males have been observed engaging in agonistic behaviour and may fight each other over potential mating opportunities, or possibly to establish a dominance hierarchy. Typically, a male initiates a fight by moving on top of the other's body and tongue-flicking, after which the two snakes twine together and push in an attempt to pin each other's head to the ground.

The prey consists of insects, shrimps and even small fish. Breeding occurs from early spring to late summer; the male fish defend a territory, construct a simple cleared nest in the substrate and attract gravid females. The eggs are laid in the nest, fertilized by the male and collected by the female. The females withdraws to a nursery to incubate the eggs in her mouth for 12–14 days at 26 °C, releasing the fry after which she guards them for 5–7 days, sheltering them in her mouth when approached by predators.

Under similar conditions, infection intensities equalling 17-32 mites decreased the number of eggs laid by gravid An. crucians by nearly 100%. High mite loads also significantly decreased the fecundity of field-collected An. crucians, but to a lesser extent than those infected in the lab. Similar consequences of high Arrenurus mite infection intensities were observed in other host-mite relationships. For example, Smith and McIver (1984) found that Arrenurus danbyensis loads of greater than 5 mites decreased the fecundity of Coquillettidia perturbans females by approximately 3.5 eggs per additional mite.

In the wild, the species has been found in the basins of the Chad River, Niger River, Volta River, Senegal River, and the Gambia River. The reproductive habits of most of the species of Synodontis are not known, beyond some instances of obtaining egg counts from gravid females.

The insectivorous birds are attracted to the pulsating of the metacercariae in the sporocyst. This will cause the birds to attack and ingest the brood sacs located in the snail's tentacles. After digestion of the broodsac, sporocysts will become cercaria and further develop into adults. Adult Leucochloridium variae are hermaphroditic helminths, but can cross fertilize with other worms if in close enough proximity. The gravid adults will release their eggs into the intestines of the bird to be excreted out with the bird’s feces; thus, continuing the Leucochloridium lifecycle.

Gravid female The breeding season of G. wislizenii extends from May to June with a single clutch of 5–6 eggs being laid usually in June or July, which hatch in the late summer months of July or August. During mating no pair bond is formed between adults. A single clutch is usually laid per year but in the warmer climates towards the south, it is possible for a female to lay up to two clutches per year. Birthing and egg-laying occur in a burrow, although no nest structure is formed.

Hunter also provided case histories for at least four of the subjects illustrated in The Anatomy of the Gravid Uterus Exhibited in Figures, published in 1774.Founders of British obstetrics 'were callous murderers', Denis Campbell, 7 February 1997, The Observer, accessed May 2010 A recent review of Hunter's sources of anatomical specimens was published in 2015. Helen King indicated that the over-enthusiastic response of the media and the internet to Shelton's unreviewed speculations raised fresh questions about how medical history is generated, presented and evaluated in the media and, in particular, on the internet.

Cysticercosis is a tissue infection caused by the young form of the pork tapeworm. Infection occurs through swallowing or antiperistaltic contractions during regurgitation carrying eggs or gravid proglottids to the stomach. At this point, larvae hatch when exposed to enzymes and penetrate the intestinal wall, travelling through the body through blood vessels to tissues like the brain, the eye, muscles, and the nervous system (called neurocysticercosis). At these sites, the parasites lodge and form cysts, a condition called cysticercosis, producing inflammatory reactions and clinical issues when they die, sometimes causing serious or fatal damage.

Females have a set of red valvifers at the distal end of the abdomen, and when gravid (mated), the female abdomen swells to the point where they find it difficult to fly.Spotted Lanternfly Biology: Life Cycle, Identification, and Dispersion. Cornell College of Agricultue and Life Sciences, New York State Integrated Pest Management The lanternfly is a strong jumper and uses its wings to assist these jumps rather than making sustained flights. In traditional Chinese medicine, the spotted lanternfly is believed to be poisonous, and is used topically for relief from swelling.

Emerald cockroach wasp (left) "walking" a paralyzed cockroach to its burrow Kyle Munkittrick, on the Discover magazine website, writes that the great majority of aliens, far from being as strange as possible, are humanoid. Ben Guarino, in The Washington Post, observes that despite all the "cinematic aliens' gravid grotesquerie", earthly parasites have more horrible ways of life. Guarino cites parasitic wasps that lay their eggs inside living caterpillars, inspiring A. E. Van Vogt's 1939 story "Discord in Scarlet", Robert Heinlein's 1951 novel The Puppet Masters, and Ridley Scott's 1979 film Alien. The eponymous Alien has a "dramatic" life-cycle.

Like all potent inhalation anaesthetic agents it is a known trigger of malignant hyperthermia. Like the other potent inhalation agents it relaxes the uterus in pregnant women which is associated with more blood loss at delivery or other procedures on the gravid uterus. The obsolete (as an anaesthetic) agent methoxyflurane had a nephrotoxic effect and caused acute kidney injury, usually attributed to the liberation of fluoride ions from its metabolism. Enflurane is similarly metabolised but the liberation of fluoride results in a lower plasma level and enflurane related kidney failure seemed unusual if seen at all.

One defining feature of the species during developmental stage is the occurrence of a single egg in each egg capsule. The development of an egg embryo to a mature cysticercoid in its intermediate host requires 28 days after infection, but fully mature cysticercoid takes about 31–34 days. Adults were found from chicken after 15 days of infection with mature cysticercoid, and the gravid segments can be obtained in the faeces from 27 to 112 days. Species of flour beetle Tribolium are particularly important as intermediate host since they are the most common pest of chicken feed.

Identification often requires histological observation of the uterine branches and PCR detection of ribosomal 5.8S gene. The presence of rostellum on the scolex, a large number of uretine branches (more than 57) and prominent posterior protuberances in gravid proglottids, and wart-like formation on the surface of the larvae are the distinguishing structures. To date the most relevant diagnosis of taeniasis due to T. asiatica is by enzyme-linked immunoelectrotransfer blot (EITB). EITB can effectively identify it from other taenid infections since serological test indicates that immunoblot band of 21.5 kDa exhibited specificity only to T. asiatica.

Adults make their homes within holes in various mangrove trees and maintain an arboreal existence whereas the young are strictly terrestrial for the first year of their lives. As the Utila iguana cannot successfully lay its eggs in the mangrove swamps, the gravid females are forced to migrate to nearby sandy beaches in order to bury their clutches of eggs so they can incubate in the hot sun. After digging their nest burrows and laying their eggs, the females abandon the nests and return to the mangroves. Sixty to seventy-four days later the hatchlings emerge and move back to the swamps.

The head of an ant: Chitin reinforced with sclerotisation This female Pandinus scorpion Has heavily sclerotised chelae, tail and dorsum, but has flexible lateral areas to allow for expansion when gravid Arthropods are covered with a tough, resilient integument or exoskeleton of chitin. Generally the exoskeleton will have thickened areas in which the chitin is reinforced or stiffened by materials such as minerals or hardened proteins. This happens in parts of the body where there is a need for rigidity or elasticity. Typically the mineral crystals, mainly calcium carbonate, are deposited among the chitin and protein molecules in a process called biomineralization.

In 1934 she left Columbia and until 1937 worked in the Department of Histology and Embryology at the Lithuanian University of Health Sciences. In 1938 she conducted important experiments which involved exposing female guinea pig foetuses to testosterone. She showed for the first time that this can give rise to an increase of masculine sexual behavior in adulthood. Danchakoff published many books as well as scientific papers, possibly her last publications being Le sexe; rôle de l'hérédité et des hormones dans sa réalisation in 1949 and Effects of cancer provoking chemical substances on gravid guinea pigs and their fruits in 1950.

Covering seed beds with a physical material, such as cheesecloth, or covering the soil of crops with tarred felt discs can prevent gravid Delia flies from laying their eggs on the crop. Covering crops as a cultural control may also complement and improve the use of biological controls such as entomopathogenic fungi and nematodes as it produces a high-humidity climate that is favourable to these pathogens. However, completely covering crops is not a common practice as the crop covers were found to damage crop growth, can be expensive, and are time consuming to install and remove.

Corydoras kanei is a small species of catfish from the family Callyichthydae endemic to Brazil where it is found in the Negros River basin. It is externally similar to Corydoras atropersonatus, but its spots are denser and unlike the former, it has caudal markings - markings on its tail fins. Breeding can be accomplished by feeding a mixture of live foods and catfish pellets, after which frequent cold water changes can trigger them to spawn. A gravid female will lay around 60 eggs; heavy oxygenation of the water is likely to be more efficacious at saving fry than using methylene blue.

Furthermore, it is thought that these additional sources of food are sources of not only calcium, but also other nutrients including phosphorus, sodium, iron, copper, and selenium. It has also been hypothesized that osteophagy is a practice necessary for the maintenance of desert tortoise shells. This parallels the phenomenon of osteophagy in birds, in which snail shells are ingested by egg-laying females to supplement the increased calcium needed for eggshell formation. Therefore, it would be expected that the increased physiological needs of juvenile and gravid female tortoises would also increase mineral demands and promote ingestion of bones, stones, and soil.

Skatole is one of many compounds that are attractive to males of various species of orchid bees, which apparently gather the chemical to synthesize pheromones; it is commonly used as bait for these bees for study. It is also known for being an attractant for the Tasmanian grass grub beetle (Aphodius tasmaniae). Skatole has been shown to be an attractant to gravid mosquitoes in both field and laboratory conditions. Because this compound is present in feces, it is found in combined sewage overflows (CSO), as streams and lakes containing CSO water have untreated human and industrial waste.

When rivers rise and spread over the floodplain, they create oxbow lakes and sloughs, and inundate terrestrial vegetation, which in turn provides protection and a nutrient-rich habitat for larval fish and fry. Once the water temperature has reached , and all the other criteria are met, gar move into the grassy, weed- laden shallows to spawn. Actual spawning occurs when males gather around gravid females, and begin writhing, twisting, bumping into, and slithering over the tops of females, an activity which triggers the release of eggs. Males release clouds of milt to fertilize the eggs as they are released into the water column.

In the wild, the species is endemic to Lake Tanganyika, which has an observed temperature range of , an approximate pH of 8.5 – 9, and dH range of 4-15. The fish inhabits the littoral to benthic zones in the lake, over shell, sand, and mud bottoms, and has been found at depths of up to , but most commonly between . The reproductive habits of most of the species of Synodontis are not known, beyond some instances of obtaining egg counts from gravid females. Spawning likely occurs during the flooding season between July and October, and pairs swim in unison during spawning.

In northeast Africa, it occurs in the White Nile from Khartoum into the Jebel and Ghazal River systems, as well as the Baro River. In western Africa, the species is known from the Chad River basin, the Niger River basin, the Volta River, the Senegal River, the Gambia River, the Geba River, the Oueme River, and the Casamance River. The reproductive habits of most of the species of Synodontis are not known, beyond some instances of obtaining egg counts from gravid females. Spawning likely occurs during the flooding season between July and October, and pairs swim in unison during spawning.

Medullary bone tissue (endosteally derived, ephemeral, mineralization located inside the medulla of the long bones in gravid female birds) has been reported in at least one Allosaurus specimen, a shin bone from the Cleveland-Lloyd Quarry. Today, this bone tissue is only formed in female birds that are laying eggs, as it is used to supply calcium to shells. Its presence in the Allosaurus individual has been used to establish sex and show it had reached reproductive age. However, other studies have called into question some cases of medullary bone in dinosaurs, including this Allosaurus individual.

When Collopy falls ill Manus sends Finbarr one of his potions, "Gravid Water", to help him. However, Finbarr administers the wrong dosage, which causes rapid weight gain and eventually leads to Collopy's death. Manus also devises a scheme to get Collopy and Father Fahrt an audience with Pope Pius X, so that Collopy can win papal support for the lavatory campaign. However, Manus is aware that the Pope will have little time for Collopy and Fahrt, and enjoys the spectacle of their humiliation, as the angry Pope, in a mixture of Latin and Italian, quite literally sends them to Hell.

Boyd's forest dragons spend the majority of their time perched on the trunks of trees, usually at around head height, although daily movements can exceed on the ground. When approached, they will usually move around to the opposite side of the tree, keeping the trunk between them and their harasser. Unlike most other lizards, Boyd's forest dragons don't bask in the sun, instead letting their body temperature fluctuate with air temperature (thermoconforming rather than thermoregulating). The one possible exception to this general rule is gravid (pregnant) females, which are often observed sitting on or beside forest roads and exhibit elevated body temperatures.

Once a gravid female lands on a plant, tactile and contact chemical stimuli are major factors affecting acceptance or rejection of the site for egg deposition. Once a female lands on a host plant, it will go through a "drumming reaction" or a rapid movement of the forelegs across the surface of a leaf. This behavior is believed to provide physical and chemical information about the suitability of a plant. P. rapae is shown to prefer smooth hard surfaces similar to a surface of an index card over rougher softer textures like blotting paper or felt.

However, indicators are sometimes compromised, such as when non-indicators mimic indicators or when indicators are time- dependent, only becoming evident after a certain lag time. The following example of a pregnancy test will make use of such an indicator. Modern pregnancy tests do not use the pregnancy itself to determine pregnancy status; rather, human chorionic gonadotropin is used, or hCG, present in the urine of gravid females, as a surrogate marker to indicate that a woman is pregnant. Because hCG can also be produced by a tumor, the specificity of modern pregnancy tests cannot be 100% (because false positives are possible).

Daily shedding of mature cercariae opportunistically encyst on the skin of tadpoles and adult frogs, particularly the dark spots of the fore and hindlegs. Tadpoles then become infected by ingestion of such encysted metacercariae or inhalation of free cercariae and attach onto the large intestine and become gravid. During the process of metamorphosis, the process at which tadpoles structurally mature into adult frogs, flukes migrate superiorly into the small intestine, as far as possible as to elude being dispensed. As the intestine shortens after metamorphosis and adolescent frogs begin development of a protein diet, the remaining flukes return to the rectum.

In 1999, she discovered and prepared the first known fossils of a gravid (egg-containing) turtle. In 2005, along with paleontologist Darla Zelenitsky, she described the oogenus Reticuloolithus: fossilized eggshells found in Alberta and Montana, believed to have been laid by maniraptoran dinosaurs such as oviraptorosaurs or dromaeosaurids. In 2003, while working in South America, Sloboda discovered a fossil footprint in Plaza Huincul, Argentina. The footprint was described as a new ichnospecies by paleontologists Rodolfo Coria, Philip J. Currie, Alberto Garrido, and David Eberth, who honored Sloboda by naming it Barrosopus slobodai, which translates as "Sloboda's muddy foot".

Richard Bleiler (New York, NY: Charles Scribner's Sons, 2003), pages 449. John Clute describes Ryhope wood in Lavondyss as a "metamorphic terrain of daunting rigor, an excremental sign-saturated inscape charged with twisting energy." He goes on to call the final chapters "superbly deranging and intense", concluding that "Lavondyss begins to seem like a thing in itself, inexplicable and gravid." Mythago Wood and Lavondyss have been described as being significant because they are pure fantasy works that take place in an innovative, yet startlingly ordinary realm. Holdstock’s writing in these works has been described as an impressive mixture of poetic style and sensitivity.

A lack of circulating body fluids, principally blood volume. This is usually (though not exclusively) caused by some form of bleeding, anaphylaxis, or pregnancy with gravid uterus. Peri- arrest treatment includes giving IV fluids and blood transfusions, and controlling the source of any bleeding - by direct pressure for external bleeding, or emergency surgical techniques such as esophageal banding, gastroesophageal balloon tamponade (for treatment of massive gastrointestinal bleeding such as in esophageal varices), thoracotomy in cases of penetrating trauma or significant shear forces applied to the chest, or exploratory laparotomy in cases of penetrating trauma, spontaneous rupture of major blood vessels, or rupture of a hollow viscus in the abdomen.

Prior to 1989, 20 fatal cases were reported in Australia. Although tick paralysis is of concern in domestic animals and livestock in the United States as well, human cases are rare and usually occur in children under the age of 10. Tick paralysis occurs when an engorged and gravid (egg-laden) female tick produces a neurotoxin in its salivary glands and transmits it to its host during feeding. Experiments have indicated that the greatest amount of toxin is produced between the fifth and seventh day of attachment (often initiating or increasing the severity of symptoms), although the timing may vary depending on the species of tick.

Note: the criterium of >600g is used with the term "macromastia" in this source: Hypertrophy of the breast can affect the breasts equally, but usually affects one breast more than the other, thereby causing asymmetry, when one breast is larger than the other. The condition can also individually affect the nipples and areola instead of or in addition to the entire breast. The effect can produce a minor size variation to an extremely large breast asymmetry. Breast hypertrophy is classified in one of five ways: as either pubertal (virginal hypertrophy), gestational (gravid macromastia), in adult women without any obvious cause, associated with penicillamine therapy, and associated with extreme obesity.

C. felis eggsAn adult gravid female flea that has consumed a full blood meal will begin to produce between 20 and 30 microscopic (0.5 mm) non-adhesive white ovoid eggs per day, laying them individually and continually at a rate of about one per hour until she dies (under ideal conditions it might be possible for her to produce between 2,000 and 8,000 eggs in her lifetime, though most only manage to produce around 100 before being consumed by their host during grooming activity). The eggs are dispersed freely into the environment. Within two to seven weeks a certain proportion will then hatch into larvae.

The larvae of L. sericata are highly gregarious, to the point that their survival depends upon grouping. The aggregated oviposition behavior of gravid L. sericata females leads to large aggregates of same-age larvae, which have been shown to experience faster development and lower predation as opposed to smaller aggregates or aggregates of variously-aged larvae. The resulting larval masses are able to thermoregulate, raising their own temperature and therefore decreasing their development time, leading to better survival. This thermoregulation may result from the way larvae forage; they are constantly moving and turning over, which could at least in part lead to the temperature rise experienced in larval masses.

This includes a whole age class of juveniles and gravid females, in order to make sure reproduction is occurring, and occurring steadily. Once this goal is met, the next requirement for de-listing is to make sure that the habitats of these populations are not in danger or susceptible to habitat destruction. Finally, like the fourth requirement in the first recovery plan, the last criteria for delisting is that all six populations remain stable and hopefully increasing steadily within a period of ten to fifteen years. In order to take all the necessary steps in these recovery plans, some actions need to be taken.

No modern reptile is known to lay their eggs on the seafloor, so these eggs likely originated in a different environmental setting. Ken Carpenter notes that while it's not possible to be completely sure how these eggs ended up on the seabed, some possibilities include carcasses of dead gravid females being washed out to sea and releasing its eggs when by splitting open, carried out to sea by floods, or drifting out on mats of vegetation. At least two clutches of hard-shelled turtle eggs preserved in volcanic ash are known from the Canary Islands. These eggs were likely buried in the debris by large tortoises.

Ideal spawning habitat was at the upper ends of riffles with sandy and gravelly bottoms interspersed with larger cobble. Hubbs, et al. went on to state that gravid or pregnant female E. spectabile were reported to contain anywhere from twenty to two hundred and fifty eggs. The eggs of this particular species are tolerant of a wide range of temperature with good hatching success from 10 C to 27 C (50 F to 81 F). The hatching success of this fish is relatively high as well has the yearling success due to its nature of seeking out large mouth bass nests for food and protection from predation.

Push–pull technology involves use of behaviour- modifying stimuli to manipulate the distribution and abundance of stemborers and beneficial insects for management of stemborer pests. It is based on in- depth understanding of chemical ecology, agrobiodiversity, plant-plant and insect-plant interactions, and involves intercropping a cereal crop with a repellent intercrop such as Desmodium uncinatum (silverleaf)Glover et al., "Plant perennials to save Africa's soils", Nature 489, 359–361 (20 September 2012) (push), with an attractive trap plant such as Napier grass (pull) planted as a border crop around this intercrop. Gravid stemborer females are repelled from the main crop and are simultaneously attracted to the trap crop.

Spawning season: In Texas, females began ripening in February, and a few were gravid in July; peak spawning in May and June (males displayed breeding coloration from February into June, or July, with greatest color intensity in May; Gunter 1950); may occur in earlier in the spring (Simpson and Gunter 1956). Sublette et al. (1990) reports spawning in New Mexico from spring – fall, at least in southern portion of state. Spawning location: During spawning, male and female swim into vegetation with fine leaves; there eggs are released and fertilized; eggs have mucous threads with which they are attached to plant material (Foster 1967). McLane (1955) noted that male courtship behavior was observed near clumps of Naias and Vallisneria.

Since that time their habitat has been reduced to the Blue Hills south of Boston, The Berkshires in Western Massachusetts as well as parts of the Connecticut River Valley, notably in the area of the Holyoke Range. The snake is so rare in the state that it is rarely encountered by people and is considered endangered, making it illegal to harass, kill, collect, or possess. Generally, this species is found in deciduous forests in rugged terrain. During the summer, gravid (pregnant) females seem to prefer open, rocky ledges where the temperatures are higher, while males and nongravid females tend to spend more time in cooler, denser woodland with more closed forest canopy.

Gravid female Lepeophtheirus salmonis on Atlantic salmon, Salmo salar Sea lice cause physical and enzymatic damage at their sites of attachment and feeding, which results in abrasion-like lesions that vary in their nature and severity depending upon a number of factors, including host species, age, and general health of the fish. Whether stressed fish are particularly prone to infestation is unclear. Sea-lice infection causes a generalized chronic stress response in fish since feeding and attachment cause changes in the mucus consistency and damage the epithelium resulting in loss of blood and fluids, electrolyte changes, and cortisol release. This can decrease salmon immune responses and make them susceptible to other diseases and reduce growth and performance.

The total length (including tail) of the specimens of B. campbelli which are available ranges from the type specimen, an adult male (Freire-Lascano, 1991), to for a large gravid female (Freire- Lascano and Kuch, 2000), to for a specimen from Imbabura, Ecuador, and another of from the type locality. The scalation includes 21–25 (usually 23) rows of dorsal scales at midbody, all of which are keeled except for the first rows. The posterior dorsals have tubercular keels, even in small specimens, while in large specimens these keels are highly elevated. There are 152-167/159-177 ventral scales in males/females and 51-64/48-60 paired subcaudal scales in males/females.

Ctenocephalides felis felis The cat flea belongs to the insect order Siphonaptera which in its adult stage is an obligatory hematophage. Adults of both sexes range from 1–2 mm long and are usually a reddish-brown colour, although the abdomens of gravid females often swell with eggs causing them to appear banded in cream and dark brown. Like all fleas, the cat flea is compressed laterally allowing it to slip between the sometimes dense hairs of its host just above the top layer of the skin, resulting in an extremely thin insect that may be difficult to observe even if the host's coat is pure white. The cat flea affects both the cat and the dog worldwide.

The extent to which other species found in the area parallel Ixodes holocyclus in this and other aspects of their biology is not known. The graphs show the average seasonal prevalence of instars and types, observed over an eight-year period, which includes six years of detailed field observation, and collection, supported by information and specimens from many people. Ixodes holocyclus emerged from this survey as the dominant acarine ectoparasite of mammals and avians in the study area, its population dwarfing those of other tick species, and various species of mites. As distinct from instars (the life cycle stages separated by metamorphosis), only one particular type within an instar has been graphed at this stage - gravid females.

One of the smallest fish based on the minimum size at maturity is Paedocypris progenetica from Indonesia, with mature females measuring as little as in standard length. This fish, a member of the carp family, has a translucent body and a head unprotected by a skeleton. One of smallest fish based on the minimum size at maturity is Schindleria brevipinguis from Australia, their females reach 7 mm (0.28 in) and males 6.5 mm (0.26 in), Males of S. brevipinguis have an average standard length of ; a gravid female was . This fish, a member of the goby family, differs from similar members of the group in having its first anal fin ray further forward, under dorsal fin 4.

Two Halobates on the shore of Oahu, Hawaii, with upper individual facing left and lower facing right They are small insects with a body that is up to long and broad, and a leg span up to at least . They lack wings, have long antennae, short front legs used for catching prey (and, in the male, for holding the female during breeding), long middle legs used for propulsion, and somewhat shorter rear legs used for steering. The nymphs resemble miniature versions of the adult. The sexes are quite similar, except that males are thinner than females and have the rear part of the body modified into genitalia, and when gravid the females may have a notably plump abdomen.

The aggreagtions are normally formed around a natural or man-made structure such as the canopy of the kelp forest or piers and occur at depths of . The mating fish break off into smaller groups, a gravid female will swim to the substrate and males will perform courtship displays and rubbing himself against her flanks and nibbling at her fins. While they are mating, the females change colour to dark grey or black on the upper body, and bright white on their underparts, while males also darkens to an overall charcoal colour, broken by black vertical bars and white spots. The males and females release the sperm and eggs at the same time, normally around sunset.

The genus and species were first described in 2016 based on two gravid females collected in 2015. The type locality of Parsigecko ziaiei is from the Koh-e Homag Protected Area north of Zakin, Hormozgan Province in Iran, at an altitude of . The genus name derives from the word "Pars" which is an old name for Iran and seat of the Persian Empire which was centered in south-central Iran. The species was named in honor of Hooshang Ziaie, a lecturer and ecologist at Islamic Azad University, North Tehran branch and former head of three provincial offices of the Department of Environment (Iran), "in recognition of his remarkable and outstanding efforts toward wildlife conservation in Iran".

A pair of Taenia proglottids, dried and resembling sesame seeds, each containing hundreds of eggs Lifecycle of T. saginata inside and outside of the human body The lifecycle begins with either the gravid proglottids or free eggs (embryophores) with oncospheres (also known as hexacanth embryos) being passed in the feces, which can last for days to months in the environment. Sometimes, these segments will still be motile upon excretion—they either empty themselves of their eggs within a matter of minutes, or in some species, retain them as a cluster and await the arrival of a suitable intermediate vertebrate host. The intermediate host (cattle, pigs, rodents, etc., depending on the species) must then ingest the eggs or proglottids.

Catanduanes mud crab industry is being supported by the Bureau of Fisheries and Aquatic Resources, Department of Science and Technology, Department of Environment and Natural Resources, Department of Labor and Employment and Catanduanes State University. The provincial government is maintaining the Catanduanes Crab Center (CCC) which serves as a source of crablets for grow-out and fattening by fishpond operators. It carries out a special program for "queen" or "gravid" crabs designed to ensure the sustainability of the industry in the province, which originally owned the "crab capital of the Philippines" title. The province's mud crab industry is focusing on the production of female crabs that play an important role in marketing, particularly in Asian countries such as Japan, Taiwan, Hong Kong and Singapore.

From his early sketches in Paris or in Normandy, Latour's technique had always been sure, self-reliant and fluid; he never sought to describe but rather to evoke with an innate sense of formal ellipsis and economy of means. His impressionist schooling gave him a feel for atmospheric skies, moving waters and intense ambiances that he produced through the supple strokes of his brush. From the start too he sought to push very far the simplification of forms, leaving details aside to attain comprehensible and vivid, though pared down, visions of the world. His work is akin to visual haikus: the painting bears the somewhat hard trace of his brush; his drawings are "written" in hasty and tense ink gravid with allusion.

Rummy-nose tetras present serious challenges even to experienced aquarists from the standpoint of breeding, primarily due to two factors: the likelihood of sterility ensuing if the prospective parents are maintained in water with too high a level of dissolved calcium ions, and the slow growth rate of the fry. An additional problem is that gender differentiation is difficult by visual inspection alone, making pair selection partly a matter of luck unless an obviously gravid female is available for selection. Again, identical remarks apply to all three species listed above. The breeding aquarium for the rummy-nose tetra, in addition, needs to be sterilised prior to use, as the fish produces eggs that are notoriously sensitive to bacterial and fungal infection.

As rat snakes are ectothermic species, they require sunlight and heat to maintain their body temperatures. Across their range in North America each species of rat snake has different ideal body temperatures. In Ontario, the average ideal body temperature of a rat snake is 28.1 degrees Celsius with free ranging gravid females tending to require a bit higher in order to meet their thermoregulatory requirements for gestation. With ambient air temperatures over the course of their entire active season (from May to September) almost never reaching the required 28.1 °C, rat snakes in Ontario resort to basking habitats where conditions allow temperatures to rise above normal and up to 43 degrees Celsius at the hottest times of day and year.

Ferrous metal wire mesh screens are commonly used to protect sea turtle nests from predators' excavating and devouring the eggs and hatchlings. A new concern is that nestlings' delicate magnetic sense may not develop normally in the presence of the magnetic field interference from these steel mesh cages. The effects of the use of steel mesh as a cage material may not be known for many years until assessments can be made of the success rate of the first adult populations that developed within such cages begin attempting landfall for nest-making. Gravid turtles or their hatchlings may also be affected by the presence of magnetic fields arising from power cables, iron debris, steel seawalls or other human activities that locally modify earth's magnetic field.

Egg binding in reptiles is quickly fatal if left untreated; therefore, gravid females who become very lethargic and cease feeding need immediate medical treatment in order to treat the potentially life-threatening condition. Egg binding can occur if an egg is malformed and/or too large, the animal is weakened by illness, improper husbandry, stress, or if hormonal balances are wrong (producing weak contractions). Factors that can contribute to the risk of egg binding include calcium deficiency, breeding animals that are too young or too small, not providing suitable laying areas (leading to deliberate retention of eggs), and overfeeding of species in which clutch size is dependent on food intake, such as the Veiled Chameleon. In the context of behavioral ecology, egg binding can be an important factor in limiting clutch size.

The myometrium stretches (the smooth muscle cells expand in both size and numberSteven's and Lowe Histology p352) during pregnancy to allow for the uterus to become several times its non-gravid size, and contracts in a coordinated fashion, via a positive feedback effect on the "Ferguson reflex", during the process of labor. After delivery, the myometrium contracts to expel the placenta, and crisscrossing fibres of middle layer compress the blood vessels to minimize blood loss. A positive benefit to early breastfeeding is a stimulation of this reflex to reduce further blood loss and facilitate a swift return to prepregnancy uterine and abdominal muscle tone. Uterine smooth muscle has a phasic pattern, shifting between a contractile pattern and maintenance of a resting tone with discrete, intermittent contractions of varying frequency, amplitude and duration.

Swordtails are some of the easiest fish for amateur aquarist to breed, if the conditions of the tank are appropriate and it contains both males and females reproduction will occur without intervention. Often all female groups which have come from a mixed gender tank will be pregnant on arrival, creating a breeding population when the fry sexually mature at around three months of age, later stages of pregnancy can be seen without much difficulty as a dark gravid spot will develop near the anal fin. Males can be distinguished from females by the presence of a Gonopodium, a modified anal fin used to impregnate the female during breeding. A ratio of one male to three or four females is recommended to ensure that individual females will not be overly harassed to breed.

Several attempts have been made at better understanding the spatial ecology of Burmese pythons in the Everglades, including capture analysis and radiotelemetry studies. Since the recognition of the breeding population of pythons, researchers have made an effort to note the capture history (date, location, and time) as well as characteristics (mass, length, sex, reproduction condition, and gut contents) of each animal to better characterize the python's activity patterns, spread, and ecology.Dove, C. J., R. W. Snow, M. R. Rochford, and F. J. Mazzotti. 2011. "Birds consumed by the invasive python (Python molurus bivittatus) at Everglades National Park, Florida, USA." The Wilson Journal of Ornithology 123:126-131. More than 2,000 pythons have been captured since 2005, including hatchling pythons, gravid females, and adults in excess of 17.5 ft (5.33 m) in total length.

Other than a scalpel, no specialised surgical equipment is needed for a resuscitative hysterotomy. The American Heart Association recommends that healthcare facilities that may be required to treat a case of maternal cardiac arrest should keep in stock an emergency equipment tray for the purpose, including a scalpel with a No. 10 blade, a Balfour retractor, surgical sponges, Kelly and Russian forceps, a needle driver, sutures and suture scissors - but the procedure should commence regardless of whether the tray is available. Basic aseptic measures, such as pouring antiseptic solution over the woman's abdomen prior to incision, may be considered as long as this adds no delay. An assistant should manually displace the gravid uterus to the woman's left throughout the procedure until the fetus has been delivered, to assist the simultaneous efforts of those resuscitating the woman.

In 2013 she also dubbed Elsa for the Disney film Frozen, performing the Danish version of the song "Let it go" ("Lad det ske"), which won an Oscar on 2 March 2014. Rosenberg was chosen for the part also because she played the role of Elphaba in Wicked, which in the Broadway- version was originally played by Idina Menzel, who voices Elsa in original version. Between 2011 and 2014 Danmarks Radio held a series of concerts in different locations in Denmark where famous Disney songs were performed by DR UnderholdningsOrkestret, DR VokalEnsemblet and artists such as Stig Rossen, Annette Heick, Henrik Launbjerg, Monique, Jesper Asholt, Thomas Meilstrup and Pelle Emil Hebsgaard. Since 2017, her partner is the Swedish singer and producer Albin Fredy Ljungqvist.Maria Lucia er gravid: “Jeg glæder mig helt enormt til at møde det lille vidunder” They live in Vesterbro.

After insemination by a male tick, or sometimes before, a female feeds on blood in order to gain the nutrients for the egg mass to mature. Adult females engorge for a period of 6–30 days, the time again being temperature dependent. (The 30-day engorgement time is derived from laboratory culture colonies.) Under natural conditions, the time taken for an adult female to engorge while on the host varies from 6 to 21 days, the period being longest in cool weather. When fully engorged (replete), the adult female drops off the host to the ground. After 11–20 days the gravid female starts to lay a batch of 2000 to 6000 eggs (20-200 eggs per day over 16–34 days) into moist vegetation such as leaf and branch litter, under the bark of trees and shrubs, or in foliage near the tips of branches.

Small tubercles grow on the outer part of his first several pectoral fin rays and his body develops a pinkish-purple coloration.Lachner, EA. 1952. Studies of the Biology of the Cyprinid Fishes of the Chub Genus Nocomis of Northeastern United States. American Midland Naturalist 48.2:433-466. When the water temperature reaches 16°-19 °C he finds an area in low to moderate current, typically 0.5-1m deep and begins to build a pebble nest. Nest construction begins with the river chub male creating a shallow depression 0.5-1m in diameter by removing the stones with his mouth and depositing them on the lateral margins. Next, collecting a relatively uniform set of up 10,000 pebbles about 1 cm in size from as far away as 25m, he builds a short platform and then a 20–30 cm high circular mound with a central trough on the upstream slope. When a gravid female enters the trough he presses her against the side by placing his caudal peduncle over hers and lodging her head between his opercle and pectoral fin.

Active bands include Gravenhurst (Warp), Team Brick (Invada), The Heads (Invada), Gonga (Invada), Joe Volk (Invada), Fuck Buttons (ATP - now moved to London), Hunting Lodge (Yosada), SJ Esau (Anticon, Twisted Nerve), Bronnt Industries Kapital (Static Caravan), Zoon van snooK (Lo Recordings, Mush Records), Aut (Fällt), Geisha (Crucial Blast) and Defibrillators (Gravid Hands). Bristol was also a home to post-rock music, with bands such as Flying Saucer Attack and Movietone. Bristol is home to many live music venues including the 2000-seat Bristol Beacon, formerly Colston Hall, named after Colston Street and the Colston School that once occupied the site, which can attract big names, the Trinity Centre (a community-run converted Church in the Old Market area of Bristol), the O2 Academy which is part of the national touring circuit for rock bands, the Anson Rooms (part of the University of Bristol Union), the Mothers Ruin, The Thekla, Fiddler's, the Bristol Folk House, Start the Bus, the Hatchet, the Fleece, the Croft, the Cooler and the Louisiana. The Colston Hall was renamed in 2020, following three years of consultation, after protests regarding Edward Colston's ties to the Atlantic slave trade.

Napier grass produces significantly higher levels of attractive volatile compounds (green leaf volatiles), cues used by gravid stemborer females to locate host plants, than maize or sorghum. There is also an increase of approximately 100-fold in the total amounts of these compounds produced in the first hour of nightfall by Napier grass (scotophase), the period at which stemborer moths seek host plants for laying eggs, causing the differential oviposition preference. However, many of the stemborer larvae, about 80%, do not survive, as Napier grass tissues produce sticky sap in response to feeding by the larvae, which traps them, causing the death of about 80% of larvae. Legumes in the genus Desmodium (silverleaf, D. uncinatum and greenleaf, D. intortum), on the other hand, produce repellent volatile chemicals that push away the stemborer moths. These include (E)-β-ocimene and (E)-4,8-dimethyl-1,3,7-nonatriene, semiochemicals produced during damage to plants by herbivorous insects, which are responsible for the repellence of Desmodium to stemborers. Desmodium also controls striga, resulting in significant yield increases of about 2 tonnes/hectare (0.9 short tons per acre) per cropping season.
