On the other hand, many of the baby boys that pediatricians refer to urology because of undescended testicles actually turn out to have what are called retractile testes, which do not need surgery, said Dr. Aseem R. Shukla, a pediatric urologist at the Children's Hospital of Philadelphia and an associate professor of urology at the University of Pennsylvania School of Medicine.

Most have retractile or partially retractile claws, a baculum. The Viverrinae range in size from the African linsang with a body length of and a weight of to the African civet at and .
|

Most members of this group have non-retractile claws (the fisher, marten, red panda, and ringtail have retractile or semi-retractile claws) and tend to be plantigrade (with the exception of the Canidae). Other traits that separate Caniformia from Feliformia is that caniforms have longer jaws and have more teeth, with less specialized carnassial teeth. They also tend more towards omnivory and opportunistic feeding, while the feliforms, other than the viverrids, are more specialized for eating meat. Caniforms have single- chambered or partially divided auditory bullae, composed of a single bone, while in feliforms, the auditory bullae are double-chambered, composed of two bones joined by a septum.

The Summer Street Bridge is a retractile drawbridge bridge built in 1899 in Boston, Massachusetts over the Fort Point Channel. It still stands, but the draw was welded shut and the motors removed in 1970. It was the site of a terrible streetcar crash on the night of November 7, 1916. The Summer Street Bridge is one of only four retractile drawbridges left in the US, two of which are in Boston.

Idiopathic sclerosing mesenteritis (ISM) is a rare disease of the small intestine, characterized by chronic inflammation and eventual fibrosis of the mesentery. It has also been called mesenteric lipodystrophy, or retractile mesenteritis.
|
|
Its long, curved claws are semi-retractile. Its head-and-body length is , with a long tail and a weight range from . Females are smaller than males. It is the largest viverrid in Africa.
|
|
A testis which can readily move or be moved between the scrotum and canal is referred to as retractile. Cryptorchidism, hypospadias, testicular cancer, and poor semen quality make up the syndrome known as testicular dysgenesis syndrome.

Rhinophore-sheath with smooth margin. Branchial plumes 6, small, simply pinnate, completely retractile within a cavity with smooth margin. Foot produced behind in a fairly long tail, the anterior end abruptly rounded and simply labiate. Integument with spicules.
|
|
Dendrocometes is a genus of suctorian infusoria, characterized by the repeatedly branched attached body; each of the lobes of the body gives off a few retractile tentacles. It is parasitic on the gills of the so-called freshwater shrimp Gammarus pulex.
|
|
The rhinophores are simple and resemble the oral tentacles. They are distant, subulate, tapering and they project outward. They are not retractile, and are without pockets. The oral tentacles are shorter, thickened at the base, tapering, projecting laterally and horizontally and curved backward.
|
|
Genet Genets are slender cat-like animals with a long body, a long ringed tail, large ears, a pointed muzzle and partly retractile claws. Their fur is spotted, but melanistic genets have also been recorded. They have musk glands and anal sacs.Kingdon, J. 1997.

Scrotal ultrasonography of undescended testis: (a) Normal testis in the scrotum (b) Atrophic and decreased echogenicity of the contralateral testis of the same patient seen in the inguinal region The most common diagnostic dilemma in otherwise normal boys is distinguishing a retractile testis from a testis that will not descend spontaneously into the scrotum. Retractile testes are more common than truly undescended testes and do not need to be operated on. In normal males, as the cremaster muscle relaxes or contracts, the testis moves lower or higher ("retracts") in the scrotum. This cremasteric reflex is much more active in infant boys than older men.
|
|
Colonies range in length up to at least 240mm, with a symmetrical slightly tapering round-tipped cylindrical rachis and a tapering peduncle of between one fifth and one third of the total length of the colony. The rachis is covered all round with dimorphic polyps, radially arranged with respect to the longitudinal axis. Siphonozoids are packed between the bases of the retractile autozooids, which have inconspicuous non-retractile bifurcated calyces. Colour is variable and permanent; individual colonies may be entirely reddish brown, pink or mauve, yellow, white or cream, or the rachis may be purple to reddish purple, with a yellow, white, pink or brownish peduncle.

|
Cats have retractile claws, slender muscular bodies and strong flexible forelimbs. Their teeth and facial muscles allow for a powerful bite. They are all obligate carnivores, and most are solitary predators ambushing or stalking their prey. Wild cats occur in Africa, Europe, Asia and the Americas.
|
|
Knives are also mentioned. Hani and kif, as predators, also have sharp retractile claws and sharp teeth. The mahendo'sat have tough, non-retractable claws, which are often used for utilitarian purposes, but using these in a fight is seen as a sign of madness in their culture.
|
|
Another specificity of many species of Ceratosoma is the kind of "horn" covering the gills, which is like a lure and acts as a defensive chemical weapon that will scare any potential predator who dares to bite this part. The gills and the rhinophores are retractile in internal sheaths.
|
|
The external soft parts are similar to those of Ariophanta, but larger, and not fully retractile within the shell. The mucous pore is of moderate size, there is no distinct overhanging lobe or a small one. The sole of the foot is undivided and very smooth. There are no shell-lobes.

Sigmurethra is a taxonomic category of air-breathing land snails and slugs, terrestrial pulmonate gastropod molluscs. This is an informal group which includes the majority of land snails and slugs. The two strong synapomorphies of Sigmurethra are a long pedal gland placed beneath a membrane and retractile tentacles.Lunarejo. et al. 2008.
|
|
Colonies are cylindrical without axis, and the rachis is generally longer than the peduncle. The colony may be radially or bilaterally symmetrical. Autozooids have non-retractile, bifurcated calyces with many sclerites.The Pennatulacea of Southern Africa (Coelentrata, Anthozoa), Annals of the South African Museum Volume 99 May 1990 part 4, Cape Town.

|
The members of the Felinae have retractile claws that are protected by at least one cutaneous lobe. Their larynx is kept close to the base of the skull by an ossified hyoid. They can purr owing to the vocal folds being shorter than . The cheetah Acinonyx does not have cutaneous sheaths for guarding claws.
|
|
The surface of the mantle shows irregular dark reddish-brown blotches. Behind the rhinophores there is a large horse shoe shaped spot. There are no mantle papillae in front of the non-lamellate, non-retractile rhinophores. The mantle ridge is situated at either side of the anus and is reduced to three pairs of bifid tentacles.
|
|
The polyps are golden brown, brown or blackish, the ones on the pinnules being paler in colour; they may make the axis appear dark red. The size and shape of the polyps vary across the colony, with the polyps most distant from the holdfast being more elongate than the others. Each polyp has six, non-retractile, unbranched tentacles.
|
|
This is a multi-segmented worm of variable length, a worm with 300 segments being about long. The prostomium is roughly pentagonal. Like other members of the genus, the prostomium bears two pairs of antennae, a pair of eyes and a pair of large, retractile, nuchal organs. The proboscis is eversible and is divided into two distinct parts.
|
|
This taxon includes the majority of land snails and slugs. The two strong synapomorphies of Stylommatophora are a long pedal gland placed beneath a membrane and two pairs of retractile tentacles (Dayrat & Tillier). Several families in this group contain species of snails and slugs that create love darts. Stylommatophora are known from the Cretaceous to the Recent periods.
|
|
Nimravus was around in body length. With its sleek body, it may have resembled the modern caracal, although it had a longer back and more dog-like feet with partially retractile claws. It probably hunted birds and small mammals, ambushing them like modern cats, rather than chasing them down. Nimravus competed with other false sabre-tooths such as Hoplophoneus.
|
|
The three large pinnate branchial plumes on the dorsal surface are non-retractile and the anus is located between them. The colouring of this nudibranch is variable across the animal's range. The body colour is creamy-white with narrow longitudinal lines, some broken, in varying shades of brown. Sometimes these lines merge in places giving transverse bands of colour.

Range map of the three species of genus Lophotis Lophotis is a genus of bustard in the family Otididae. The genus contains three species, all found in Africa. All three species are sometimes placed in the genus Eupodotis, and are closely related to that genus and the genus Afrotis. One distinctive feature of the genus is a pink retractile crest.
|
|
Larvae are both terrestrial and aquatic, and feed primarily on algae and fungi. Some species are important pollinators of tropical crops such as the cocoa bean. Larvae of species in the Dasyheleinae subfamily are characterized by an anal segment with retractile posterior prolegs. Larvae are aquatic and adults do not feed on vertebrate blood, nor do they prey on other insects.
|
|
The tympanum is very distinct, oval, and slightly smaller than the eye; a glandular fold is present above it. Skin is smooth and shiny. Fingers and toes have slightly swollen tips; no webbing is present. The terminal phalange of all but the innermost toe have a sharp, curved non-retractile bony claw (a trait shared by all species in the genus).
|
|
This animal has an elongated slender body with eight short arms and two very long retractile tentacles, all of which have suckers. It has relatively long diamond-shaped fins, which run more than half the length of the mantle. Its mantle is up to long. Its eyes are covered with a membrane which is part of the skin covering the head.
|
|
Bohadschia marmorata is cylindrical in shape and grows to about long. The body wall is tough and leathery and has a rough texture due to the calcareous spicules it contains. It is covered in translucent papillae up to across and a few short spines. The anterior end of the body is somewhat narrowed and has a mouth surrounded by a ring of retractile tentacles.
|
|
Its peristomium is small and short, covering the posterior prostomium margin. Its tentacular cirri and antennae are alike but shorter, similar to papillae in length. The species dorsum and ventrum are covered by large papillae, forming between 3 and 4 rows, giving it a rough appearance. It counts with dorsal cirri on all parapodia, which is short and mamilliform to lemon-shaped, counting with a retractile cirrostyle.
|
|
There is some variation between individuals in this species, and the gills (retractile) and rhinophores (contractile) range in colour from a translucent straw-color, through to pink and light orange.Debelius, Helmut, 2001, Nudibranchs and Sea Snails: Indo-Pacific Field Guide, IKAN - Unterwasserarchiv, Frankfurt, Germany.P.L. Beesley, G.J.B. Ross, A. Wells, Mollusca - The southern synthesis, vol.5, CSIRO, 1998,David Behrens, Nudibranch behaviour, New World Publication INC.

Oncus planci is a cylindrically-shaped sea cucumber growing up to in length, and in diameter they have a brownish color, often with irregular dark brown patches. They have ten tentacles The eight large and two small feeding tentacles are branched, leaf-like, and lighter in colour than the body. They are suspension feeders. They have retractile tube feet arranged in five zigzag double rows.
|
|
Non-surgical stretching of the foreskin may be used to widen a narrow, non-retractable foreskin. Stretching may be combined with the use of a corticosteroid cream. Beaugé recommends manual stretching for young males in preference to circumcision as a treatment for non-retractile foreskin because of the preservation of sexual sensation. Paraphimosis can often be effectively treated by manual manipulation of the swollen foreskin tissue.
|
|
The mouth is large, muscular, strong and retractile. The respiratory tube is pretty stout. Its cavity is capacious, entirely open, provided with two branchiae placed on the left side, the larger of which, describes a pretty large semicircle. The trunk is cylindrical, very much developed, flexible, capable of being turned in every direction at the will of the animal, and of elongating itself in a remarkable manner.

Dial number plates were made from steel with a white vitreous enamel face. Black 302 telephone sets were equipped from the factory with straight brown textile-covered cords until 1952, when synthetic rubber (Neoprene) jacketed cords became standard equipment. Optional retractile coiled cords were available both in textile and rubber jackets since the early 1940s. The 302 was a rugged and easily repaired desk telephone.
|
|
The glowing arm tips are clustered together far above the animal's head, diverting attack away from critical areas. If a predator were to bite off an arm tip, the vampire squid can regenerate it. They have eight arms but lack feeding tentacles, and instead use two retractile filaments in order to capture food. They combine the waste with mucus secreted from suckers to form balls of food.
|
|
These sea cucumbers reach around in length and have ten branched oral tentacles ranging in colour from orange to black. This species has a football shape with a leathery skin ranging in colour from yellowish white to dark brownish-black and is covered with five rows of retractile tube feet.Gosner, K.L. 1978. This species of Sea Cucumber can move about two feet per day.
|
|
Their rims are stiffened with chitin and may contain minute toothlike denticles. These features, as well as strong musculature, and a small ganglion beneath each sucker to allow individual control, provide a very powerful adhesion to grip prey. Hooks are present on the arms and tentacles in some species, but their function is unclear. The two tentacles are much longer than the arms and are retractile.
|
|
The segments are not externally recognizable, and the seventeen body segments each comprise five outer annulations. In the pharynx, there are one or two retractile stylets on each of the three jaws. Between the male and female sex opening of the hermaphrodite animals there are five or fewer annulations. On the ventral surface, there is a central accessory copulation pore next to the gonopores, but this is absent in young animals.
|
|
Orchiopexy can also be performed to resolve a testicular torsion. If caught early enough and the blood supply can be restored to the testicle, this operation can be performed to prevent further occurrence of torsion. If the blood supply has been interrupted for too long, an orchiectomy must be performed. Sometimes orchiopexy is also done preventively in adults in cases in which the patient has the bell-clapper deformity, retractile testicles.
|
|
Ristella is a genus of skinks endemic to the Western Ghats of southwestern India. They are commonly known as cat skinks because of their retractile claws. This genus can be instantly identified by the presence of only four fingers in forelimbs in all the species (instead of the usual five). All the members look more or less similar and are drab dark brown to blackish in complexion with paler undersides.
|
|
The martens constitute the genus Martes within the subfamily Guloninae, in the family Mustelidae. They have bushy tails and large paws with partially retractile claws. The fur varies from yellowish to dark brown, depending on the species, and is valued by trappers for the fur trade. Martens are slender, agile animals, adapted to living in the taiga, and inhabit coniferous and northern deciduous forests across the Northern Hemisphere.
|
|
Genets are a member of the genus Genetta and are slim animals with features similar to cats. Their features include retractile claws and the ringed tail. Although true purring is exclusive to felids and viverrids, other animals such as raccoons produce purr-like vocalization. Animals that produce purr-like sounds include mongoose, bears, badgers, foxes, hyaenas, rabbits, squirrels, guinea pigs, tapirs, ring-tailed lemurs and gorillas while eating.
|
|
As an adult, Psychropotes longicauda has eighteen short feeding tentacles, each with a leathery terminal disc with retractile processes projecting around the margin. Its body is very flexible and can grow to a length of between . It is approximately cylindrical but broadest and somewhat flattened near the anterior end. At the posterior end there is a dorsal, tail-like appendage up to long, either pointed or with a pair of unequal-length tips.
|
|
A robust, medium-sized gecko, with a large, triangular head. It has a short, flattened, carrot shaped like tail, that ends in a knob. This tail can be autotomised to distract predators, however unlike other lizards they have only one cleavage point at the base, meaning it must sacrifice its whole tail in the event. It has long slender limbs with non-retractile claws on digits, of which the outer most one is opposable.
|
|
Physiologic phimosis, common in males 10 years of age and younger, is normal, and does not require intervention. Non-retractile foreskin usually becomes retractable during the course of puberty. If phimosis in older children or adults is not causing acute and severe problems, nonsurgical measures may be effective. Choice of treatment is often determined by whether circumcision is viewed as an option of last resort to be avoided or as the preferred course.

The Kdatlyno are chiefly known for their touch sculpture, their sonar "vision". Their race was formerly subjugated by the Kzinti until freed by the humans. In appearance they are a physically large and powerful bipedal species with muscular build, rough scaly skin, retractile claws and thick hides, growing up to eight feet tall. They have no eyes, having evolved on a world which instead drove the development of echolocation rather than vision.
|
|
The vampire squid (Vampyroteuthis infernalis, lit. "vampire squid from Hell") is a small cephalopod found throughout temperate and tropical oceans in extreme deep sea conditions. Unique retractile sensory filaments justify the vampire squid's placement in its own order, Vampyromorphida, as it shares similarities with both octopuses and squid, but is now known to be more closely related to octopuses. As a phylogenetic relict, it is the only known surviving member of its order.
|
|
He also found that 1% of those unable to fully retract experienced phimosis at ages 14–17, the remainder were partially able to. The findings were supported by further research by Kayaba et al (1996) on a sample of over 600 boys, and Ishikawa and Kawakita (2004) found that by age 15, 77% of their sample of boys could retract their foreskins. Beaugé (1997) reports that boys may assist the development of retractile foreskin by manual stretching.

L. glaberrima is an arborescent coral and grows in a sympodial manner; this means that the original axis stops growing after a while, with one or more side branches forking out randomly, only to stop growing as other branches take over. The skeleton is composed of a spiny keratin-like material, laid down in concentric layers. This is overlain by a layer of living tissue from which the polyps project. Each of these has six unbranched, non-retractile tentacles.
|
|
But the feet, with the pads, are considerably narrower, the carpals and metatarsals converging and meeting above so that a much larger area of the under surface is hairy. The area between the four main digits and the plantar pad is covered with short hair, and the pads of the third and fourth digits of the hind foot are separated as in the Viverrinae, not confluent as in the Paradoxurinae. The retractile claws are not protected by skin-lobes.
|
|
The different larval instars are fairly uniform in appearance. They have pinkish grey bodies with a maroon line down the dorsum, flanked by bluish green and regular reddish brown markings on the sides. The head is dark with yellow markings, while the neck and anal shields are likewise dark, but with a broad, yellow median line. The well-developed honey-gland is located on the seventh segment, and retractile white tubercles with protective spines are located on the eighth segment.
|
|
Anthopleura thallia typically has a base about wide, a column about long and an oral disc wide. The lower part of the column has many sticky, cup-shaped warts in about 36 vertical rows. The margin of the column has several outgrowths of the body-wall known as acrorhagi, which are well armed with cnidocytes (stinging cells). On the oral disc there are two to four whorls of thirty to sixty tapering, blunt-tipped, fully retractile tentacles and a central mouth.
|
|
The first one is around the head part and the second one is close to the gills. The purple margin of the mantle and foot is an unbroken line. Another specificity of the species is the kind of "horn" covering the gills, which is like a lure and acts as a defensive chemical weapon that will scare any potential predator who dares to bite this part. The gills and the rhinophores are retractile in internal sheaths and their basis has a purple margin.

A second duct of unknown origin and function entering portal of male copulatory organ. Male copulatory organ reniform, quadriloculate, with short tapered cone; walls of chambers comparatively thick; distal tube elongate; retractile filament not observed. Germarium pyriform, dorsoventrally looping right intestinal cecum; Mehlis’ gland not observed; uterus delicate, with variable diameter. Vaginal sclerite with distal tube having single recurve before its attachment to vaginal vestibule; pear-shaped chamber with thick walls and small cavity; vaginal canal and seminal receptacle not observed.

The single species in the family Amphibolidae is archaic and retains an operculum. It lives at such a high tidal level that it could perhaps be considered semi- terrestrial. Members of the family Chilinidae are confined to temperate parts of South America, and the Latiidae are limpet-like and confined to New Zealand. Basommatophorans are characterized by having their eyes located at the base of their non-retractile tentacles, rather than at the tips, as in the true land snails Stylommatophora.
|
|
The fossa has a large, prominent rhinarium similar to that of viverrids, but has comparatively larger, round ears, almost as large as those of a similarly sized felid. Its facial vibrissae (whiskers) are long, with the longest being longer than its head. Like some mongoose genera, particularly Galidia (which is now in the fossa's own family, Eupleridae) and Herpestes (of Herpestidae), it has carpal vibrissae as well. Its claws are retractile, but unlike those of Felidae species, they are not hidden in skin sheaths.

|
Even in those sea cucumbers that lack regular tube feet, those that are immediately around the mouth are always present. These are highly modified into retractile tentacles, much larger than the locomotive tube feet. Depending on the species, sea cucumbers have between ten and thirty such tentacles and these can have a wide variety of shapes depending on the diet of the animal and other conditions. Many sea cucumbers have papillae, conical fleshy projections of the body wall with sensory tube feet at their apices.
|
|
Viverra species are distinguished externally from the other genera of the Viverrinae by the structure of the fore feet: the third and fourth digits have lobes of skin, which act as protective sheaths for the retractile claws. The pads the feet are surrounded by hair. They have a long and narrow skull, with narrow, nearly parallel- sided, not strongly constricted waist. Their postorbital processes are small and a little in front of the middle point between the tip of the premaxillae in front and of the occipital crest behind.

According to some accounts, phimosis prevented Louis XVI of France from impregnating his wife for the first seven years of their marriage. She was 14 and he was 15 when they married in 1770. However, the presence and nature of his genital anomaly is not considered certain, and some scholars (such as Vincent Cronin and Simone Bertiere) assert that surgical repair would have been mentioned in the records of his medical treatments if this had indeed occurred. Non-retractile prepuce in adolescence is normal, common, and usually resolves with increasing maturity.
|
|
Skull of a common genet The common genet has a slender, cat-like body, a small head with a pointed muzzle, large oval ears, large eyes and well-developed whiskers up to in length. Its legs are short, with cat-like feet and semi-retractile claws. Its fur is dense and soft, and the coat is pale grey, with numerous black markings. The back and flanks are marked with about five rows of black spots, and a long black stripe runs along the middle of the back from the shoulders to the rump.

The pathophysiological process behind radiation's RILP nerve damage has been discussed since the 1960s and is still without a precise definition. Consensus does exist on a progression of RILP symptoms, with a stepping (a time delay) between two periods of plexopathy onset, the first from radiation injury and the later from fibrosis. Proposed mechanisms of the early nerve damage include microvascular damage (ischemia) supplying the myelin, radiation damage of the myelin, and oxygen free radical cell damage. The delayed nerve damage is attributed to compression neuropathy and a late fibro-atrophic ischemia from retractile fibrosis.

Around 40 years of age, the root of the Tree-of-Life plant begins to smell delicious to all Breeders, and they eat it and metamorphose into the Protector stage via a virus that lives in the plant. A Protector's joints expand to give his muscles a greater moment arm, his skin wrinkles into a tough armor, and his nails turn into retractile claws. A second heart develops near the groin, the mouth fuses into a beak, and all sexual characteristics disappear. The most important change is that the brain expands, giving a Protector a tremendous intellect.

The Summer Street Bridge over Fort Point Channel in Boston is a variant type called a retractile bridge. This bridge is oriented northwest–southeast, with the northwest-bound lanes of traffic retracting diagonally to the north, and the southeast-bound lanes retracting diagonally to the west. Some retractable bridges are also floating bridges, such as the Hood Canal Bridge. Two other floating bridges in Washington state used to have retractable spans but were replaced with new floating bridges without retractable spans: the Evergreen Point Floating Bridge (replaced in 2016) and Lacey V. Murrow Memorial Bridge (replaced after it accidentally sank in 1990).

A retractile testis high in the scrotum can be difficult to distinguish from a position in the lower inguinal canal. Though various maneuvers are used to do so, such as using a cross-legged position, soaping the examiner's fingers, or examining in a warm bath, the benefit of surgery in these cases can be a matter of clinical judgment. In the minority of cases with bilaterally nonpalpable testes, further testing to locate the testes, assess their function, and exclude additional problems is often useful. Scrotal ultrasound or magnetic resonance imaging performed and interpreted by a radiologist can often locate the testes while confirming absence of a uterus.
|
|
The most commonly used hormone therapy is human chorionic gonadotropin (hCG). A series of hCG injections (10 injections over five weeks is common) is given and the status of the testis/testes is reassessed at the end. Although many trials have been published, the reported success rates range widely, from roughly 5% to 50%, probably reflecting the varying criteria for distinguishing retractile testes from low inguinal testes. Hormone treatment does have the occasional incidental benefits of allowing confirmation of Leydig cell responsiveness (proven by a rise of the testosterone by the end of the injections) or inducing additional growth of a small penis (via the testosterone rise).

M. mitchellii is a robust and distinctive burrowing sea anemone. The column is pear-shaped with a rounded base, and is divided into a scapus, the main part of the column, and a scapulus, a smooth retractile region; the physa, or basal region, is able to adhere firmly to a hard surface but is not normally attached because the animal habitually burrows. The scapus often has sand grains sticking to it. The oral disc bears up to 36 tentacles in several cycles; the inner cycle contains seven tentacles which tend to be raised above the central mouth while the remaining tentacles are spread widely over the surface of the sediment.

Paired dorsal bar with enlarged medial end. Hook with elongate slightly depressed thumb, delicate point, uniform shank; FH loop nearly shank length. Testis subspherical, usually with indentation of posterior margin suggesting two posterior lobes; proximal vas deferens dorsoventrally looping left intestinal cecum; seminal vesicle a simple dilation of distal portion of vas deferens, lying just posterior to male copulatory organ; vas deferens entering large subspherical ejaculatory bulb; ejaculatory duct entering portal to male copulatory organ; large vesicle (prostatic reservoir?) lying to right of male copulatory organ. Male copulatory organ reniform, quadriloculate, with short tapered cone, elongate distal tube, and variable apparently retractile filament (usually not observed); walls of two distal chambers thick, walls of chambers becoming thinner proximally.

Larva adult in June, clothed with short thin hairs, green with a yellow line on back and sides, yellow subdorsal oblique spots and a brown retractile head; on certain Prunus and Amygdalus, more rarely on birch, hazel and cherry. Pupa very smooth, rounded everywhere, pale brown, with thin lighter and darker markings; although fastened only by the cremaster, not by a girth, it is closely applied with its underside to its support The butterfliesoccur from July until late in October near woods, in avenues and gardens. They rest concealed among the foliage, and can fly rather fast and without interruption. They visit flowers, particularly umbellifers, and have also been observed at bait.

The yellow-crested cockatoo (Cacatua sulphurea) also known as the lesser sulphur-crested cockatoo, is a medium-sized (about 34-cm-long) cockatoo with white plumage, bluish-white bare orbital skin, grey feet, a black bill, and a retractile yellow or orange crest. The sexes are similar. The yellow-crested cockatoo is found in wooded and cultivated areas of East Timor and Indonesia's islands of Sulawesi and the Lesser Sundas. It is easily confused with the largerBirdLife Species Factsheet, retrieved 10 February 2010Birds in backyards factsheets: Sulphur-crested Cockatoo and more common sulphur-crested cockatoo, which has a more easterly distribution and can be distinguished by the lack of pale yellow coloring on its cheeks (although some sulphur-cresteds develop yellowish patches).

The review concludes that topical steroids should be tried first, and praeputioplasty has advantages over surgical circumcision. This article also provides a good discussion of the difficulty distinguishing pathological from physiological phimosis in young children and alleges inflation of phimosis statistics for purposes of securing insurance coverage for post-neonatal circumcision in the United States. Some authors use the terms "physiologic" and "pathologic" to distinguish between these types of phimosis; others use the term "non-retractile foreskin" to distinguish this developmental condition from pathologic phimosis. In some cases a cause may not be clear, or it may be difficult to distinguish physiological phimosis from pathological phimosis if an infant appears to have discomfort while urinating or demonstrates obvious ballooning of the foreskin.

Paired dorsal bar with spatulate medial end. Hook with elongate depressed thumb, delicate point, uniform shank; filamentous hook (FH) loop nearly shank length. Testis ovate, lying sinistroposterior to germarium; proximal vas deferens, prostatic reservoir not observed; seminal vesicle an indistinct dilation of distal vas deferens, lying just posterior to MCO; ejaculatory bulb not observed. Male copulatory organ (MCO) reniform, quadriloculate, with short distal cone, elongate tube with comparatively thick walls, delicate apparently retractile distal filament; walls of two distal chambers thick, walls of proximal two chambers thinner but comparatively rigid. Germarium pyriform, shaped as an inverted comma; germarial bulb lying diagonally at body midlength, with elongate dorsoventral distal loop around right intestinal cecum; ootype lying to left of body midline, with well-developed Mehlis’ gland and giving rise to delicate banana- shaped uterus when empty.

Buried penis on a circumcised 30 year old male not due to obesity Buried penis in a circumcised 40 year old male due to obesity Buried penis (also known as hidden penis or retractile penis) is a congenital or acquired condition, in which the penis is partially or completely hidden below the surface of the skin. It was first described by Edward Lawrence Keyes in 1919 as the apparent absence of the penis and as being buried beneath the skin of the abdomen, thigh, or scrotum. Further research was done by Maurice Campbell in 1951 when he reported on the penis being buried beneath subcutaneous fat of the scrotum, perineum, hypogastrium, and thigh. A buried penis can lead to obstruction of urinary stream, poor hygiene, soft tissue infection, phimosis, and inhibition of normal sexual function.

Species of Sphaerosyllis, however, always exhibit papillae on the pharyngeal opening, their pharyngeal tooth is conical and is always located on or very near to the anterior margin of the pharynx. They usually count with a short proventricle, itself provided with large muscle cell rows, large posterior acicula (which is distally bent at 90°), blades of compound chaetae which are short and unidentate, and offspring developing ventrally, females without capillary notochaetae, only present on males. Sphaerosyllis horrockensis, Sphaerosyllis belizensis, and Sphaerosyllis centroamericana were transferred to Erinaceusyllis under these distinguishing characteristics. At the same time, Prosphaerosyllis is close to Erinaceusyllis, but its species' pharyngeal teeth are rhomboidal to oval and located near the middle of their pharynges; also their antennae are short, tentacular and their dorsal cirri have a bulbous cirrophore and retractile cirrostyle.

Instead of a rubber flap, saloon style doors are often made from plastic, acrylic, or plexiglass, and the panels are fitted with weather seal to help keep weather outside. Another common feature is an adjustable catch to restrict the opening of the device to either one direction or the other; for example, to allow the pet to come in for the night, but not go out again until the owner releases the catch the next morning. Some pets, mostly cats with their retractile claws and flexible paws, learn to circumvent one-way pet doors, especially the "flap-within-flap" design. Most also have a locking mechanism of some kind, and can be closed off by sliding a rigid plate into parallel rails on the left and right of the interior side of the pet door, useful during bad weather or when the owners are traveling with their pets.
