The phylogeny of gharials is significantly impacted by homoplasy. These endangered reptiles are made up of two different species: Gavialis gangeticus and Tomistoma schlegelii. An important distinction between the two is that under morphological analysis of extant species and fossils, Tomistoma is considered a true crocodile, while Gavialis is not, with the two species' shared characteristic of fish eating being a product of homoplasy. However, molecular data suggests that the gharials are sister taxa, with their shared fish eating trait being a result of homology.

Throughout the 1970s, 80s, and 90s, yellow perch and smallmouth bass have been the primary target of anglers. Today, there is a controversial effort to stock the lake with yellow walleye. Many fishermen are blaming the walleye stocking effort for the recent decline in yellow perch catches. However, both fishing pressure and the recent arrival of fish-eating cormorants certainly share some of the blame.

The fish may spawn several times in a season, and the timing of spawning is not fully understood. The spawning runs of the peamouth make an impressive natural spectacle as the brightly colored fish move into areas of warm, shallow, flowing water in large numbers. These schools attract many fish-eating predators. The newly hatched fry form schools near the shore, moving into deeper water later in the summer.

This environment had a large variety of lifeforms also present in Middle-Cretaceous North Africa, due to the connection of South America and Africa as parts of the supercontinent Gondwana. As a spinosaurid, the traits of Oxalaia skull and dentition indicate a partly piscivorous (fish-eating) lifestyle similar to that of modern crocodilians. Fossil evidence suggests spinosaurids also preyed on other animals such as small dinosaurs and pterosaurs.

Hadrosteus rapax ("Rapacious Strong-Bone") is a large arthrodire placoderm from the Late Frasnian Kellwasserkalk facies of Germany. It had large, double- pronged inferognathals, and serrated edges along its mandible, strongly suggesting that it was a fish-eating predator. The head had a triangular snout, and the trunkshield was short, but high, with a median dorsal plate that was broader than wide. The average skull length is about 16 centimeters.
|
|
Having variable teeth, a condition called heterodonty, is rare in modern reptiles but more common in primitive pterosaurs. The heterodont dentition in Dorygnathus is consistent with a piscivorous (fish-eating) diet. The fifth digit on the hindlimbs of Dorygnathus was unusually long and oriented to the side. Its function is not certain, but the toe may have supported a membrane like those supported by its wing-fingers and pteroids.

In general, crocodilians are stalk-and- ambush predators, though hunting strategies vary depending on the individual species and the prey being hunted. Terrestrial prey is stalked from the water's edge and then grabbed and drowned.Grigg and Gans, pp. 229–330. Gharials and other fish-eating species sweep their jaws sideways to snap up prey, and these animals can leap out of the water to catch birds, bats, and leaping fish.

Humans are one of the definitive hosts of Diphyllobothrium tapeworms, along with other carnivores; fish-eating mammals (including canids, felids, and bears), marine mammals (dolphins, porpoises, and whales), and (a few) birds (e.g. gulls) may also serve as definitive hosts. Definitive hosts release eggs in faeces; the eggs then mature in ~18–20 days if under favourable conditions. Crustaceans serve as the first intermediate hosts, and Diphyllobothrium larvae develop.

The eastern osprey (Pandion cristatus) is a diurnal, fish-eating bird of prey. They live in Oceania at coastal regions of the Australian continent, the Indonesian islands, New Guinea, and the Philippines. It is usually sedentary and pairs breed at the same nest site, building up a substantial structure on dead trees or limbs. The species resides in habitat close to coasts and estuaries that provide opportunities for fishing.

Piscivoravis is an extinct genus of fish-eating ornithuromorphs known from the Early Cretaceous Jiufotang Formation (Aptian age) of western Liaoning Province, northeastern China. Piscivoravis was first named by Shuang Zhou, Zhonghe Zhou and Jingmai O'Connor in 2013 and the type species is Piscivoravis lii. Phylogenetic analysis places Piscivoravis in a more derived position than Archaeorhynchus, in a polytomy with Jianchangornis, Patagopteryx, and the clade including all more derived ornithuromorphs.

Lifecycle of Opisthorchis O. viverrini is a hermaphroditic liver fluke. Similar to C. sinensis and O. felineus, it requires three different hosts to complete its lifecycle. Freshwater snails are the first intermediate hosts in which asexual reproduction takes place, and freshwater fishes belonging to the family Cyprinidae) are second intermediate hosts in which larval development occurs. Fish–eating (piscivorous) mammals, including humans, dogs, and cats, act as definitive hosts, in which sexual reproduction occurs.

The finished dish of koi pla made of raw fish accompanied by rice and vegetables. This dish is a dietary staple of many northeastern Thai villagers and is a common source of infection with O. viverrini. The metacercarial stage is infective to humans and other fish- eating mammals, including dogs, cats, rats, and pigs. Fish contain more metacercaria from September to February, before the dry season, and this is when humans are usually infected.

Rabbi Solomon Schonfeld brought in 300 children who practiced Orthodox Judaism, under auspices of the Chief Rabbi's Religious Emergency Council. He housed many of them in his London home for a while. During the Blitz he found for them in the countryside often non-Jewish foster homes. In order to assure the children follow Jewish dietary laws (Kosher) he instructed them to say to the foster parents that they are fish eating vegetarians.

Only the Peruvian pelican shares this active foraging style (although that species never dives from such a great height), while other pelicans forage more inactively by scooping up corralled fish while swimming on the water surface. It is an occasional target of kleptoparasitism by other fish-eating birds such as gulls, skuas, and frigatebirds. They are capable of drinking saline water due to the high capacity of its salt glands to excrete salt.
|
|
Many species have developed specialized salt glands to allow them to tolerate salt water but these are poorly developed in juveniles. Some of the species prefer riverine habitats. All but two of the 20 species in this group live in far northern latitudes. The fish-eating members of this group, such as the mergansers and smew, have serrated edges to their bills to help them grip their prey and are often known as "sawbills".

Mounted skeletal reconstruction at the Denver Museum of Nature and Science Charig and Milner had proposed a piscivorous (fish-eating) diet for the closely related Baryonyx in 1986. This was later confirmed in 1997 with the discovery of partially digested fish scales found in the Baryonyx holotype. In 1998 Sereno and colleagues suggested the same dietary preference for Suchomimus. based on its elongated jaws, spoon-shaped terminal rosette, and long teeth reminiscent of those of piscivorous crocodilians.

Adult male C. acutus American crocodiles are apex predators, and any aquatic or terrestrial animal they encounter in freshwater, riparian and coastal saltwater habitats is potential prey. The snout of the American crocodile is broader than some specialized fish-eating crocodilians (e.g., gharials and freshwater crocodiles), allowing it to supplement its diet with a wider variety of prey. In addition the snout gets even broader and bulkier as the animal matures, a sign for a shift in prey items.
|
|
Other animals shown are monitor lizards which prey on fallen eggs and chicks, fishing cats and endangered gharials, a fish-eating crocodile. Young gharials call to their mother as they hatch so she can dig them out of their underground nest. The females co-operate, taking turns to guard their vulnerable young in a crèche. As the monsoon draws to a close, more birds arrive, including sarus cranes, filmed conducting their courtship dances, and millions of waterfowl.
|
|
Tomistomines have narrow or longirostine snouts like gharials. The living false gharial lives in fresh water and uses its long snout and sharp teeth to catch fish, although true gharials are more adapted toward piscivory, or fish-eating. Despite the similarity with gharials, the shapes of bones in tomistomine skulls link them with crocodiles. For example, both tomistomines and crocodiles have thin postorbital bars behind the eye sockets and a large socket for the fifth maxillary tooth.
|
|
The diet of Tanystropheus has been controversial in the past, although most recent studies consider it a piscivorous (fish-eating) reptile. The teeth at the front of the narrow snout were long, conical, and interlocking, similar to those of nothosaurs and plesiosaurs. This was likely an adaptation for catching aquatic prey. Additionally, hooklets from cephalopod tentacles and what may be fish scales have been found near the belly regions of some specimens, further support for a piscivorous lifestyle.

The seals showed a strong response when they heard the calls of mammal-eating killer whales. However, they did not respond strongly when hearing familiar calls of the local fish-eating population. The seals, therefore, are capable of habituating to the calls of harmless predators, in this case harmless killer whales. While some researchers prefer to simply describe the adaptive value of observable habituated behavior, others find it useful to infer psychological processes from the observed behavior change.

In the 1960s, it was discovered that DDT was preventing many fish- eating birds from reproducing, which was a serious threat to biodiversity. Rachel Carson wrote the best-selling book Silent Spring about biological magnification. The agricultural use of DDT is now banned under the Stockholm Convention on Persistent Organic Pollutants, but it is still used in some developing nations to prevent malaria and other tropical diseases by spraying on interior walls to kill or repel mosquitoes.

In Venezuela it is found between in the Andes and Serranía del Perijá, most often in cloud forests between . It has low rates of reproduction and is threatened by hunting and destruction of habitat. Endangered mammals include Geoffroy's spider monkey (Ateles geoffroyi) and Musso's fish-eating rat (Neusticomys mussoi). grey- capped hemispingus (Hemispingus reyi) 25 endemic birds species with restricted ranges are reported in the ecoregion of which four are found only in the montane forest ecoregion.

Chambal Garden The Chambal Garden is located in southeastern Rajasthan, India on the banks of the Chambal River in the town of Kota (once part of the Rajput kingdom). The well-groomed garden's centerpiece is a pond replete with gharials, which used to house magars as well. The pond can be crossed via a suspension bridge or by boat to allow a closeup view of the fish-eating reptiles. The garden draws large number of couples .

An orca breaching in Hood Canal The Salish Sea is home to 253 fish species contained within 78 families and 31 orders. These species encompass one myxinid, two petromyzontids, 18 chondrichthyans, two chondrosteans, and 230 teleosts. In addition, the sea hosts 37 marine mammal species, most notably Steller sea lions, humpback whales, and orcas. While mammal-eating transient orcas are gradually increasing in population, fish- eating southern resident orcas have struggled to survive due to low salmon populations.

Lesser fish eagles are fish-eating birds that have feet adapted to aid in gripping slippery fish. They have strongly curved talons, and spicules along the underside of the birds' toes help to grip fish as they pull them from the water. There are two subspecies: Haliaeetus humilis humilis, which is native to the Malaysian Peninsula, Sumatra, Borneo, and Sulawesi; and Haliaeetus humilis plumbeus, which is native to Kashmir through southeast India, Nepal, and Burma towards Indochina.

The banded darter has a diverse range of temperatures it can tolerate; it can survive in water between 32 and 80 °F, but its preferred temperature range is between 72 and 76 °F.Crail. 2012. Banded Darter Care. 2012. btdarters.com. As a small fish, banded darters have numerous predators including larger fish such as smallmouth bass and largemouth bass, as well as fish-eating birds like herons and egrets. This darter will compete with other darters for habitat.

The osprey or more specifically the western osprey (Pandion haliaetus) — also called sea hawk, river hawk, and fish hawk — is a diurnal, fish-eating bird of prey with a cosmopolitan range. It is a large raptor, reaching more than in length and across the wings. It is brown on the upperparts and predominantly greyish on the head and underparts. The osprey tolerates a wide variety of habitats, nesting in any location near a body of water providing an adequate food supply.

Flying Spaghetti Monster emblem Advocates of the Church of the Flying Spaghetti Monster, or Pastafarianism, which was created in 2005 to protest the decision by the Kansas Board of Education to require the teaching of intelligent design, have designed their own version of the fish symbol, with the Flying Spaghetti Monster's characteristic "noodly appendages" and eye stalks. Another more complicated design features the previously-mentioned "Jesus fish eating Darwin fish" with the Flying Spaghetti Monster in turn attacking the Jesus fish.

Coelacanths are considered a poor source of food for humans and likely most other fish-eating animals. Coelacanth flesh has high amounts of oil, urea, wax esters, and other compounds that give the flesh a distinctly unpleasant flavor, make it difficult to digest and can cause diarrhea. Their scales themselves emit mucus, which combined with the excessive oil their bodies produce, make coelacanths a slimy food. Where the coelacanth is more common, local fishermen avoid it because of its potential to sicken consumers.

"Baby Shark" originated from a campfire song or chant. Some sources have mentioned traditional myths as a basis, others camping origins in the 20th century, and some see it as possibly developed by camp counselors inspired by the movie Jaws. It became a campfire song where each member of a family of sharks is introduced with different hand motions. Different versions of the song have the sharks hunting fish, eating a sailor, or killing people, who then go to heaven.

The mudflats are used by a wide variety of birds to feed on. Flocks of brent geese, Eurasian wigeon and Northern pintail use the estuary in the winter while waders such as dunlin, black-tailed godwit and grey plover feed on the mud and roost in the marshes and shingle ridges. sandwich and little terns nest on the shingle ridges alongside black-headed gulls. Together with great cormorants these fish eating birds hunt their prey in the rich waters of the area.

E. emlongi and Macrodelphinus (background) It had a short tail and developed limbs with webbed feet. Unlike modern sea lions, it had a set of slicing carnassials; the presence of slicing teeth (rather than purely piercing teeth as in modern fish-eating pinnipeds) suggests that Enaliarctos needed to return to shore with prey items in order to masticate and ingest them. Still, Enaliarctos had some sea lion-like characteristics, such as large eyes, sensitive whiskers, and a specialized inner ear for hearing underwater.

Both Quintus Curtius Rufus and Arrian refer to Alexander himself meeting with a tribe of fish-eating savages while on his Indian campaign.Bernheimer, p. 88. Distorted accounts of apes may have contributed to both the ancient and medieval conception of the wild man. In his Natural History Pliny the Elder describes a race of silvestres, wild creatures in India who had humanoid bodies but a coat of fur, fangs, and no capacity to speak – a description that fits gibbons indigenous to the area.

Over 400 bird species have been recorded in the Lake Nakuru/Lake Elmenteita basin. Elmenteita attracts visiting flamingoes, both the greater and lesser varieties, which feed on the lake's crustacean and insect larvae and on its suspended blue-green algae, respectively. Lake Magadi tilapia were introduced to the lake from Lake Magadi in 1962 and since that time the flamingo population has dwindled considerably. The tilapia attract many fish-eating birds that also feed upon the flamingo eggs and chicks.

During the night, the flukes settle down to the bottom of the eye, which allows the fish to have a sense of sight. A question that is then posed is why doesn't the parasite just stay in front of the retina all the time. In recent studies, it is shown that not all predators are the same for Tylodelphys. In the day time, the predators of the bullies are fish eating birds, but at night the main predators are longfin eels.

Because methylmercury is formed in aquatic systems and because it is not readily eliminated from organisms it is biomagnified in aquatic food chains from bacteria, to plankton, through macroinvertebrates, to herbivorous fish and to piscivorous (fish-eating) fish.reviewed in Wiener, J.G., Krabbenhoft, D.P., Heinz, G.H., and Scheuhammer, A.M., 2003, "Ecotoxicology of mercury," Chapter 16 in Hoffman, D.J., B.A. Rattner, G.A.

Jordanella after one month in normal water for the first batch, and in water containing 0.6PPB and 1.26PPB and 2.5PPB (parts per billion) of methylmercury for the three bottles at right. In recent years, there has been increasing recognition that methylmercury affects fish and wildlife health, both in acutely polluted ecosystems and ecosystems with modest methylmercury levels. Two reviews document numerous studies of diminished reproductive success of fish, fish-eating birds, and mammals due to methylmercury contamination in aquatic ecosystems.

They are commonly referred to as the "orcas of the Salish Sea", "fish-eating orcas", or the "SRKW" population. Unlike other resident communities, the SRKW is only one clan (J) that consists of 3 pods (J, K, L) with several matrilines within each pod. As of August 2019 there are only 73 individuals, making their population at a 30 year low. The world's oldest known killer whale, Granny or J2, had belonged to and led the J pod of the SRKW population.

About 250,000 people live on the plain with a similar number of cattle, migrating to grasslands at the edge of the floodplain when the flood arrives. The floodplain is one of the most productive areas for raising cattle in the country. The Lozi also catch fish, eating about five times as much as the national average. At the height of the flood they use fish traps and spears for fishing, and they use gill nets in the lagoons left behind by the falling flood.

The pale plumage is conspicuous from a distance at sea, and may attract other birds to a good feeding area for these fish- eating species. When seen against the sky, the white underparts also help to hide the hunting bird from its intended prey. The Inca tern has mainly dark plumage, and three species that mainly eat insects, the black tern, white- winged tern, and black-bellied tern, have black underparts in the breeding season. The Anous noddies have dark plumage with a pale head cap.

Direct fossil evidence and anatomical adaptations indicate that spinosaurids were at least partly piscivorous (fish-eating), with additional fossil finds indicating they also fed on other dinosaurs and pterosaurs. The osteology of spinosaurid teeth and bones has suggested a semiaquatic lifestyle for some members of this clade. This is further indicated by various anatomical adaptations, such as retracted eyes and nostrils; and the deepening of the tail in some taxa, which has been suggested to have aided in underwater propulsion akin to that of modern crocodilians.

Rather, it is more likely that they were adapted to browsing for food while swimming or standing in shallow water. The family, Palaelodidae, is the sister taxon of modern flamingos, and the order Phoenicopteriformes, to which both belong, probably evolved from a grebe-like ancestor. It is easy to see how a bird like Palaelodus represents an intermediate form between a diving, fish-eating grebe and a wading, invertebrate-filtering flamingo. This does not mean that the palaelodids are the ancestors of the flamingos.

A notable sign war occurs during the popular Shad Planking in Wakefield, Virginia. Every April, locals and politicians from all around the Commonwealth gather for some politicking, beer drinking, and fish eating. Nationally, in August 2007, Democrat presidential hopefuls John Edwards and Barack Obama each claimed victory for his side in the sign war that occurred at Drake University in Des Moines, Iowa. Probably one of the most famous sign wars occurs every presidential election year at the Jefferson Jackson dinner in Des Moines Iowa.
|
|
This is possibly a result of becoming more specialized for a piscivorous (fish-eating) diet, as has been suggested for the family based on fossil evidence and the semiaquatic adaptations exhibited by many species. They are also known to have fed on pterosaurs and other dinosaurs. Ostafrikasaurus lived in a subtropical to tropical environment alongside many other dinosaurs, as well as pterosaurs, crocodyliforms, fish, mammals, and invertebrates. Due to its age and location, Ostafrikasaurus indicates spinosaurids may have been globally distributed prior to the breakup of Pangaea.

Like in all spinosaurids, Siamosauruss teeth were conical, with reduced or absent serrations. This made them suitable for impaling rather than tearing flesh, a trait typically seen in largely piscivorous (fish-eating) animals. Spinosaurids are also known to have consumed pterosaurs and small dinosaurs, and there is fossil evidence of Siamosaurus itself feeding on sauropod dinosaurs, either via scavenging or active hunting. Siamosaurus' role as a partially piscivorous predator may have reduced the prominence of some contemporaneous crocodilians competing for the same food sources.

In 2003, D. renale eggs were discovered in six human coprolites in the neolithic site Arbon-Bleiche 3, Switzerland. This location is near a lake, which likely provided early humans with access to freshwater fish and frogs. The samples were dated from 3,384-3,370 BC, and is evidence that the prevalence of this infection was higher in early human history (before full understanding of proper cooking techniques). Eggs were also found in 2019 in a well-preserved largely fish-eating settlement in England dating to 900 BC.

The ears are unusually large for a member of its tribe, and are visible above the thick fur. Like other ichthyomyine rodents, montane fish-eating rats have feet adapted for swimming in water. However, the adaptations are less extreme in this species than in most others; for example, the feet are narrower, and the fringe of stiff hairs around the toes is less well developed. A short web, not quite reaching the first joint, connects the second and third and the third and fourth toes.

Fish-eating birds use beaver ponds for foraging and in some areas, certain species appeared more frequently where beaver were active than at sites with no beaver activity. Beaver modifications to streams in Poland have been associated with increased bat activity. While overall bat activity was increased, Myotis bat species, particularly Myotis daubentonii, activity may be hampered in locations where beaver ponds allow for increased presence of duckweed. These dead trees in Tierra del Fuego are a result of the construction of a dam by introduced beavers.
|
|
These adaptations may have been the result of a dietary change from terrestrial prey to fish. Unlike crocodiles, the post-cranial skeletons of baryonychine spinosaurids do not appear to have aquatic adaptations. Supplementary Information Sereno and colleagues proposed in 1998 that the large thumb-claw and robust forelimbs of spinosaurids evolved in the Middle Jurassic, before the elongation of the skull and other adaptations related to fish-eating, since the former features are shared with their megalosaurid relatives. They also suggested that the spinosaurines and baryonychines diverged before the Barremian age of the Early Cretaceous.

There are several genera, of which the most widespread is Podiceps with nine species, one recently extinct. The red-necked grebe's closest relative is the fish-eating great crested grebe of Europe and western Asia.Ogilvie & Rose (2002) 8–9 It is possible that the red-necked grebe originally evolved in North America and later spread to Europe, where a change of diet to include more insects helped to reduce competition with its larger cousin.Johnsgard, PA (1987) 130–135 Fossils of the species dating to the middle Pleistocene have been found in Italy.

A vampire bat feeding on a pig (taxidermy specimens) Vampire bats hunt only when it is fully dark. Like fruit-eating bats, and unlike insectivorous and fish-eating bats, they emit only low-energy sound pulses. The common vampire bat feeds primarily on the blood of mammals (occasionally including humans), whereas both the hairy-legged vampire bat and white-winged vampire bat feed primarily on the blood of birds. Once the common vampire bat locates a host, such as a sleeping mammal, it lands and approaches it on the ground.

Phytoplankton live just a few days, whereas the zooplankton eating the phytoplankton live for several weeks and the fish eating the zooplankton live for several consecutive years. Aquatic predators also tend to have a lower death rate than the smaller consumers, which contributes to the inverted pyramidal pattern. Population structure, migration rates, and environmental refuge for prey are other possible causes for pyramids with biomass inverted. Energy pyramids, however, will always have an upright pyramid shape if all sources of food energy are included and this is dictated by the second law of thermodynamics.

|
While other dromaeosaurids filled a variety of specialized ecological niches, mainly those of small predators or larger fish-eating forms, eudromaeosaurs functioned as large- bodied predators of often medium to large-sized prey. Aside from their generally larger size, eudromaeosaurs are characterized by several features of the foot. First, there were differences in the positions of the grooves which anchored blood vessels and keratin sheathes of the toe claws. In primitive dromaeosaurids like Hesperonychus, these grooves ran parallel to each other on either side of the claw along its length.

The tower on the summit elevates the hill to above sea level. The area is towards the east of the Surrey Hills AONB surrounded by the Greensand Ridge, including Holmbury Hill and Pitch Hill, as well as the nearby escarpment of the North Downs from Box Hill to Newlands Corner. A species of fish-eating dinosaur, Baryonyx walkeri, was discovered in clay pits just south of Dorking. The creature had a long curved claw on each hand and remains of its last meal were discovered fossilised in its ribcage.

Intensive aquaculture has brought humans in conflict with fish-eating birds such as cormorants. Large flocks of pigeons and starlings in cities are often considered as a nuisance, and techniques to reduce their populations or their impacts are constantly innovated. Birds are also of medical importance, and their role as carriers of human diseases such as Japanese encephalitis, West Nile virus, and influenza H5N1 have been widely recognized. Bird strikes and the damage they cause in aviation are of particularly great importance, due to the fatal consequences and the level of economic losses caused.

These cranes feed mainly on plants although they are omnivorous. In the summer grounds they feed on a range of plants including the roots of hellebore (Veratrum misae), seeds of Empetrum nigrum as well as small rodents (lemmings and voles), earthworms and fish. They were earlier thought to be predominantly fish eating on the basis of the serrated edge to their bill, but later studies suggest that they take animal prey mainly when the vegetation is covered by snow. They also swallow pebbles and grit to aid in crushing food in their crop.

The Stockholm Convention on Persistent Organic Pollutants, listed 9 of the 12 most dangerous and persistent organic chemicals that were (now mostly obsolete) organochlorine pesticides. Since chlorinated hydrocarbon pesticides dissolve in fats and are not excreted, organisms tend to retain them almost indefinitely. Biological magnification is the process whereby these chlorinated hydrocarbons (pesticides) are more concentrated at each level of the food chain. Among marine animals, pesticide concentrations are higher in carnivorous fishes, and even more so in the fish- eating birds and mammals at the top of the ecological pyramid.

Their decline and disappearance coincided with the spread of the Squalodontoidea and other primitive, fish-eating toothed whales, which certainly competed with them for food, and were ultimately more successful. A new lineage, the Paraptenodytes, which includes smaller but decidedly stout-legged forms, had already arisen in southernmost South America by that time. The early Neogene saw the emergence of yet another morphotype in the same area, the similarly sized but more gracile Palaeospheniscinae, as well as the radiation that gave rise to the penguin biodiversity of our time.

The calcar can assist the uropatagium in forming a basket or pouch to help catch and hold insects captured in flight. The calcar helps spread the uropatagium during flight, managing its camber. For species of bats that forage via trawling, such as the greater bulldog bat and the fish-eating myotis, the calcar is used to prevent the uropatagium from dragging along the surface of the water. In the hairy-legged vampire bat, the calcar is not used for flight, but rather as a sixth digit to aid in tree-climbing.

Baryonyx was the first theropod dinosaur demonstrated to have been piscivorous (fish-eating), as evidenced by fish scales in the stomach region of the holotype specimen. It may also have been an active predator of larger prey and a scavenger, since it also contained bones of a juvenile iguanodontid. The creature would have caught and processed its prey primarily with its forelimbs and large claws. Baryonyx may have had semiaquatic habits, and coexisted with other theropod, ornithopod, and sauropod dinosaurs, as well as pterosaurs, crocodiles, turtles and fishes, in a fluvial environment.
|
|
These adaptations may have been the result of a dietary change from terrestrial prey to fish. Unlike crocodiles, the post-cranial skeletons of baryonychine spinosaurids do not appear to have aquatic adaptations. Supplementary Information Sereno and colleagues proposed in 1998 that the large thumb-claw and robust forelimbs of spinosaurids evolved in the Middle Jurassic, before the elongation of the skull and other adaptations related to fish-eating, since the former features are shared with their megalosaurid relatives. They also suggested that the spinosaurines and baryonychines diverged before the Barremian age of the Early Cretaceous.

However, seldom, they will also take other aquatic animals such as frogs, crabs, mussels and large insects. In one case, a Pel's fishing owl was observed to predate a baby Nile crocodile (Crocodylus niloticus). While perched over the water, these owls detect the movement of fish from ripples in the water and swoop down to seize their prey with their powerful talons and then swoop back to their perch for consumption. Unlike many other fish-eating birds, Pel's fishing owl rarely submerge themselves or get particularly wet while hunting.
|
|
They also argued that the specimen showed a probable adaptation to a fish-eating diet: the good preservation of the mandible shows that the first three teeth were inclined anterodorsally, a character often associated with piscivory. Microraptor was an opportunistic feeder, hunting the most common prey in both arboreal and aquatic habitats. In 2019, a new genus of scleroglossan lizard (Indrasaurus) was described from a specimen found in the stomach of a Microraptor. The Microraptor apparently swallowed its prey head first, a behavior typical of modern carnivorous birds and lizards.
|
|
Once the predator has captured the prey, it has to handle it: very carefully if the prey is dangerous to eat, such as if it possesses sharp or poisonous spines, as in many prey fish. Some catfish such as the Ictaluridae have spines on the back (dorsal) and belly (pectoral) which lock in the erect position; as the catfish thrashes about when captured, these could pierce the predator's mouth, possibly fatally. Some fish-eating birds like the osprey avoid the danger of spines by tearing up their prey before eating it.

Myotis vivesi skull Myotis vivesi is the largest species in the genus Myotis in the Americas, and is similar in size to the Eurasian Myotis myotis (greater mouse-eared bat). The skull averages in length. The second largest Myotis species in the New World, Myotis velifer, has a skull long, and feet long; M. vivesi has greatly elongated hind feet, which average long. In common with other fish-eating bats, Myotis vivesi has long, efficient wings, with high aspect ratio and low wing loading, and large feet with sharp claws.

|
Secondly, serrated edges on the leading edge of owls' remiges muffle an owl's wing beats, allowing an owl's flight to be practically silent. Some fish-eating owls, for which silence has no evolutionary advantage, lack this adaptation. An owl's sharp beak and powerful talons allow it to kill its prey before swallowing it whole (if it is not too big). Scientists studying the diets of owls are helped by their habit of regurgitating the indigestible parts of their prey (such as bones, scales, and fur) in the form of pellets.

This newly transformed form of mercury (methylmercury) then begins to bio-accumulate in the many species inhabiting the contaminated waterways and ecosystems. Animals accumulate methylmercury in their body's faster, then it leaves their systems, resulting in each successive species in the food chain consuming higher levels of methylmercury. The bio-accumulation levels of toxic methylmercury are highest by larger predator fish species, fish eating animals, and humans which fish being a prominent food source for humans, causes much additional worry. Though methylmercury traces have also been found in reptiles, amphibians, invertebrates, flora, birds, and even the surrounding soil.

A5 Pod is a name given to a group of orcas (Orcinus orca) found off the coast of British Columbia, Canada. It is part of the northern resident population of orcas - a name given to the fish-eating orcas found in coastal waters ranging from mid-Vancouver Island up through the Queen Charlotte Islands of British Columbia and into the southeastern portions of Alaska. The orcas of the Northern Resident community are divided into vocally distinctive clans known as the A clan, the G clan, and the R clan. Members of the A5 Pod belong to the A clan.

DDT and polychlorinated biphenyls (PCBs) move from contaminated sediments into the water, so although the dumping of DDT stopped in 1983, the PVS remains contaminated DDT and PCBs enter the food chain through worms and micro- organisms living in the sediment. One fish may eat many of these organisms, causing the DDT and PCBs to accumulate in fish tissue. Fish-eating birds, marine mammals and birds of prey that feed on both, accumulate more of the toxins. Since 1985, fish consumption advisories and health warnings have been posted in southern California because of elevated DDT and PCB levels.

The Conservancy's long-range master plan for the Emiquon Project, meanwhile, included restoration of the parcel's natural drainage patterns to the maximum extent possible, including reconstruction of a free-flowing connection between the Illinois River and Thompson Lake. As of 2008, the refilled lakes were stocked with more than 30 species of fish, including largemouth bass, bluegill, bullhead, channel catfish, crappie, and sunfish. Several dozen fish-eating black-crowned night herons had also arrived. In addition to game fish, heritage fish were also planted in Flag Lake and Thompson Lake, such as the state-endangered redspotted sunfish and the state- threatened starhead topminnow.

Saint Lawrence is shown with the grill of his martyrdom, and the alms purse attribute as the patron of the poor. His border shows fresh fish ready for grilling, and the big fish eating the little fish, representing the rich devouring the poor, a common literary and pictorial theme of the 15th and 16th centuries. These fantastic trompe l’oeil borders were to influence the work of the Master of Mary of Burgundy 30 years later. The Cleves Master was a superb realist who showed scenes of 15th-century Utrecht, especially in the small bas-de-page pictures.

Consequently, CCAMLR campaigned for compliance with MARPOL provisions relating to waste disposal at sea, and for cutting of any material jettisoned which could form collars to entangle seals. Subsequent monitoring of entangled fur seals confirmed that entanglement is still a persistent problem, but it has halved in recent years. Trawling activities developing around Macquarie Island may affect the prey base of the primarily fish-eating Antarctic fur seals that breed on those islands. Recent work indicates that there is significant overlap between foraging areas and fisheries activities, suggesting a potential for competition for prey resources may exist.

A dusky dolphin on the Cape Peninsula west coast 51 species, or more than 50%, of the recognized species of cetaceans are present in the southern African subregion (between the equator and the Antarctic ice edge), of which 36 have been sighted in South African and Namibian waters. A vulnerable population of fish-eating killer whales are present offshore on the Agulhas Bank. Observations peak in January while few are sighted in April and May. The killer whales move in pods of 1-4 individuals and are mostly sited over the shelf edge off the south-east coast.

Only the liver was not used, as its high concentration of vitamin A is poisonous. As a carnivore, which feeds largely upon fish-eating carnivores, the polar bear ingests large amounts of vitamin A that is stored in their livers. The resulting high concentrations cause Hypervitaminosis A, Hunters make sure to either toss the liver into the sea or bury it in order to spare their dogs from potential poisoning. Traditional subsistence hunting was on a small enough scale to not significantly affect polar bear populations, mostly because of the sparseness of the human population in polar bear habitat.

Wintering adult white-tailed eagle in Hokkaido, Japan. The white-tailed eagle is a member of the genus Haliaeetus, a monophylic group comprised by 11 living species, including the closely related Ichthyophaga fish eagles which may or may not be part of a separate genus. The latter group, comprised by the lesser (Haliaeetus humilis) and the grey-headed fish eagle (Haliaeetus ichthyaetus), differ mostly in life history, being more fully devoted to fish eating and habituating wooded areas, especially in mountainous areas. In appearance the two Ichthyaetus are slenderer, longer tailed and more uniform and grey in colour than typical sea eagles.

The schelly (Coregonus stigmaticus) is a living fresh water fish of the salmon family, endemic to four lakes in the Lake District, England. Its taxonomy is disputed with some recognizing it as a distinct species and others as a variant of the widespread Eurasian whitefish species Coregonus lavaretus. It is present in Brothers Water, Haweswater, Red Tarn and Ullswater, and the population seems stable in all of these except for Haweswater where it seems to be declining. The main threats it faces are seen to be water abstraction and cormorants, and the fish-eating birds are being culled from Haweswater.

By 2007 dramatic improvements were noted in water clarity, insect populations, and the trout catch. The ODFW has captured golden shiners, another invasive species of bait fish illegally introduced to the lake. Although shiners are less successful than tui chubs at multiplying in Diamond Lake, the ODFW works to remove them and to discourage more from being added. In January 2016, Oregon revealed their plan to release up to 25,000 fish-eating tiger trout into the lake after the appearance of a single tui chub in an effort to prevent it from, once again, harming the lake.

Nile crocodile attacking wildebeest Human Crocodile Conflict Even a cruising crocodile is difficult to locate Crocodiles are ambush predators, waiting for fish or land animals to come close, then rushing out to attack. Crocodiles mostly eat fish, amphibians, crustaceans, molluscs, birds, reptiles, and mammals, and they occasionally cannibalize smaller crocodiles. What a crocodile eats varies greatly with species, size and age. From the mostly fish-eating species, like the slender-snouted and freshwater crocodiles, to the larger species like the Nile crocodile and the saltwater crocodile that prey on large mammals, such as buffalo, deer and wild boar, diet shows great diversity.

The direct impacts of salt production on waterbirds have not been widely assessed as of 2009. Although the shallow ponds created for salt production may provide suitable feeding habitats for fish-eating birds, it has also reduced the exploitable area available to the birds feeding exclusively on invertebrates. The Journal of African Ornithology has conducted comparative studies into two saline coastal wetlands that have been developed into saltpans and two others that are also saline but have no saltpans and as evaluated their findings. They reported on the quality of lagoon water, benthic macroinvertebrates and waterbird communities characterising these wetlands obtained from samples collected between September 2005 and April 2006.

Though bats can have a diet ranging from fruit to meat, M. macrophyllum is insectivorous, meaning that their diet mainly consists of insects. Stomach content analysis of these bats has revealed mainly winged insects, indicating that the majority of the insects that M. macrophyllum consumes are aerial insects. Although flying insects are the main food source of the long-legged bat, these bats have also been known to supplement their diet with animal blood, but not with fruit. Due to the prominence of its posterior extremities and large feet, researchers have suggested aquatic hunting in these bats similar to Noctilo fish-eating bats, but this has yet to be proven.

The Nile perch (Lates niloticus) was introduced into Lake Victoria in the 1950s with the objective of making the lake fisheries more productive. It is a fish-eating predator and since its introduction, many species of cichlid in the genus Haplochromis have suffered significant declines in number, and Haplochromis vonlinnei is one of these. The fish was already uncommon in the 1970s, and it has not been recorded since 1980, when several specimens were caught by trawling during a survey undertaken by Tanzania. The IUCN has listed Haplochromis vonlinnei as being "Critically Endangered" and suggests it is either exceedingly rare with very few individuals remaining, or may already be extinct.

Head of an Indian gharial, which has similarities to the head of Irritator In 1996, Martill and colleagues theorized that Irritator challengeri, with its elongated snout and unserrated conical teeth, likely had at least a partly piscivorous (fish-eating) diet. Although much of the holotype's morphology turned out to be greatly different than they thought, later studies supported these observations. Spinosaurids had very narrow and elongated jaws with relatively homogeneous pointed teeth, an arrangement found particularly in animals like the Indian gharial—the most piscivorous extant crocodilian. The long conical teeth, which in spinosaurines did not possess serrated edges, were suitable for grabbing and holding prey.

Charolais cattle, Sierra Nevada, Venezuela A capybara native to Venezuela, the largest rodent Notable mammals include the giant anteater, jaguar, howler monkey, venezuelan fish-eating rat, and the capybara, the world's largest rodent. More than half of Venezuelan avian and mammalian species are found in the Amazonian forests south of the Orinoco. Some of the more unique mammals endemic to Venezuela include the howler monkey, capybara, giant anteater, giant otter, white-bellied spider monkey, crab-eating fox, sloths and jaguars. Sloths are typically found in Venezuela's tropical rainforests, crab-eating foxes live in the vast southern region, while giant anteaters can be found in different habitats across the country.

Yacoubi met the American composer and writer Paul Bowles in Fez in 1947, and later in Tangier. Yacoubi then began doing translations for Bowles. Bowles and his wife, novelist and playwright Jane Bowles, encouraged Yacoubi to draw and paint the characters in his own stories after seeing Yacoubi's illustrations of his translations. Bowles was interested in recording music from different cultures, and invited Yacoubi to translate for him in Spain, Italy, Turkey, India, Malaysia, Hong Kong, and Japan. Bowles then transcribed Yacoubi's own stories from Maghrebi into English: "The Man and The Woman" (1956), "The Man Who Dreamed of Fish Eating Fish" (1956), and "The Game" (1961).

Aerial view of Oyster Bay National Wildlife Refuge (the near left water areas) The Congressman Lester Wolff Oyster Bay National Wildlife Refuge formerly known as the Oyster Bay National Wildlife Refuge on the north shore of Long Island consists of high quality marine habitats that support a variety of aquatic-dependent wildlife. The refuge's waters and marshes surround Sagamore Hill National Historic Site, home of Theodore Roosevelt - father of the National Wildlife Refuge System. Subtidal (underwater up to mean high tide line) habitats are abundant with marine invertebrates, shellfish and fish. Marine invertebrate and fish communities support a complex food web from waterfowl to fish-eating birds, to marine mammals.

One of the fish-eating species, the geography cone, Conus geographus, is also known colloquially as the "cigarette snail", a gallows humor exaggeration implying that, when stung by this creature, the victim will have only enough time to smoke a cigarette before dying.NIGMS - Findings, September 2002: Secrets of the Killer SnailsGeographic Cone Snail, Geographic Cone Snail Profile, Facts, Information, Photos, Pictures, Sounds, Habitats, Reports, News - National Geographic Symptoms of a more serious cone snail sting include intense, localized pain, swelling, numbness and tingling and vomiting. Symptoms can start immediately or can be delayed for days. Severe cases involve muscle paralysis, changes in vision, and respiratory failure that can lead to death.

Pachypanchax patriciae is a species of killifish from the family Aplocheilidae. It is endemic to Madagascar where it occurs in the basins of the Mananjeba, Mahavavy du Nord, Ifasy, Manehoko and Ampandra rivers in the north west of the island. The specific name of this fish honours the Malagasy conservationist Patricia Yazgi (1946-2006), who ran the charity Friends of Fishes and who supported efforts to document and conserve the freshwater fish fauna of Madagascar. This species appears to feed mainly the adults and nymphs of terrestrial insects and on the larvae of aquatic insects and its most important predators are fish-eating birds and dragonfly nymphs.

The Cheboygan River descends in its length, from above sea level, the level of Mullett Lake, to Lake Huron at above sea level. The river and other sections of the Inland Waterway are made accessible by locks maintained by the United States Army Corps of Engineers. The mouth of the Black River, south of Cheboygan, is a noted spot to look for bald eagles and other fish-eating raptors. In Cheboygan itself, U.S. Highway 23 is carried across the Cheboygan River by the Cheboygan Bascule Bridge, a Scherzer rolling lift bridge built in 1940 and added to the National Register of Historic Places in December 1999.

The infrastructure is designed to help establish full wetland habitat with a wide range of water levels. The infrastructure also allows water transfer among different areas within the NSEA to minimize the need to discharge waters to the lake. As each new phase is flooded and naturally populated with wildlife, fish samples are routinely collected and analyzed to ensure that pesticide levels in their tissues are below established safe levels for fish-eating birds. Newly flooded phases are carefully monitored for at least one year to ensure that any accumulation of pesticides through the aquatic food web do not present a risk to water birds.

The bizarre cranial morphology of Spathicephalus suggests that its feeding habits differed greatly from those of other Carboniferous tetrapods. Most stem tetrapods including baphetids were most likely piscivorous (fish-eating) given their large teeth and deep skulls, which provided attachment points for strong, fast-acting jaw muscles. The small chizel-shaped teeth of Spathicephalus would have been ill-suited for catching fish. Moreover, the flattened shape of its skull means that the depressor mandibulae, muscles that attach to the back of the skull and are responsible for opening the lower jaw, would not have had much room to anchor and therefore would have had poor mechanical advantage.

Small juveniles of in standard length may form in large schools in shallow backwaters and among cobbles and boulders near stream banks. Adult hardhead normally occur in schools in the deepest part of pools, where the slowly cruise around during the day, becoming more active in early morning and evening when they feed. In some reservoirs large adults have been observed sitting close to the surface on warm summer days which makes the vulnerable to predation bt large fish- eating birds such as the Western osprey and the bald eagle. They are predominantly bottom feeders, consuming invertebrates and aquatic plants from stream beds although they will also feed on insects and algae drifting higher in the water column.

While some areas of the river with heavily contaminated sediments have not been remediated, there is significant remediation of sediments about to start in Homebush Bay. These include the dioxin contaminated sediments near the former Union Carbide plant and the lead contaminated sediments near the former Berger Paints plant. The former AGL site has been analysed, a remediation plan developed and approved, remediation completed and construction commenced on medium to high density residential development, but the sediments, which independent research shows to be contaminated with pollutants from the AGL operations, have not yet had the investigation stage finalised (). Other areas have had sediments covered with concrete to prevent the fish eating the benthos.

Terapon jarbua is a euryhaline grunter which can tolerate a wide range of salinities from pure freshwater to up to 70% and so can live in a variety of habitats from purely marine areas through costal waters, into estuaries, coastal lagoons and freshwater. It is mainly a marine species bit it may move quite far up rivers where the water is fresh. Juveniles of T. jarbua can be numerous in intertidal area where there are sandy and are frequently recorded in tidal pools. This is a predatory species which feeds on smaller fishes but which also acts as a cleaner fish eating ectoparasites from larger fishes and is known to eat their scales which are high in calories.

The centra (vertebral bodies) of the sacrals are largely incomplete due to erosion, but preserved all of their accompanying spines with their upper edges intact. At the time of Ichthyovenators description, excavations at the site were still ongoing. Casts of the vertebrae at the Muséum National d'Histoire Naturelle, Paris After undergoing preparation in 2011, the skeleton was used as the basis, or holotype, for the type species Ichthyovenator laosensis, which was named and described in 2012 by palaeontologists Ronan Allain, Tiengkham Xeisanavong, Philippe Richir, and Bounsou Khentavong. The generic name is derived from the Old Greek word ἰχθύς (ichthys), "fish", and the Latin word venator, "hunter", in reference to its likely piscivorous (fish-eating) lifestyle.

The fish owls have large, powerful, and curved talons and a longitudinal sharp keel underneath the middle claw with all having sharp cutting edges that are very much like those of eagle owls. Unlike fish-eating diurnal raptors, they do not submerge any part of their body while hunting, preferring only to put their feet into the water, although fish owls wade into the shallows. The feathers of fish owls are not soft to the touch and lack the comb and hair-like fringes to the primaries, which allow other owls to fly silently in order to ambush their prey. Due to the lack of these feather-specializations, fish owl wing beats make sounds.

Ringed teal Worldwide, ducks have many predators. Ducklings are particularly vulnerable, since their inability to fly makes them easy prey not only for predatory birds but also for large fish like pike, crocodilians, predatory testudines such as the Alligator snapping turtle, and other aquatic hunters, including fish-eating birds such as herons. Ducks' nests are raided by land-based predators, and brooding females may be caught unaware on the nest by mammals, such as foxes, or large birds, such as hawks or owls. Adult ducks are fast fliers, but may be caught on the water by large aquatic predators including big fish such as the North American muskie and the European pike.

Cyprinodon desquamator, the only known scale-eating species of pupfish Most Cyprinodon species feed on algae, cyanobacteria and detritus, but may also supplement their diet with small crustaceans and aquatic insect larvae. Some species mainly feed on small animals like aquatic insects. C. variegatus, a species that otherwise has a diet typical of pupfish, will clean other fish by feeding on parasites on their body. In the two places where several species live together they have diverged into different niches, including the fish-eating C. maya (Lake Chichancanab), zooplankton-eating C. simus (Lake Chichancanab), amphipod- and bivalve-eating C. labiosus and C. verecundus (Lake Chichancanab), scale-eating C. desquamator (San Salvador Island lakes), and ostracod- and gastropod-eating C. brontotheroides (San Salvador Island lakes).

Due to its size, the bird is presumed to have been an excellently adapted dynamic soarer. It probably built its nest on high plateaus or similar places, where it could easily take flight by simply walking into the wind with wings spread. It was a seabird that apparently lived mainly off squid and other soft-bodied prey; the "teeth" were less saw-like than the horny serrations on the beak of the fish-eating saw-billed ducks (Merginae), pointing straight downwards instead and in the fossils often very abraded or broken. The downward-pointing "teeth" were ideal for digging into and holding slippery, soft-skinned pelagic animals such as cephalopods that were probably snatched out of the water in flight or while swimming.

Comparisons between the scleral rings of pterosaurs and modern birds and reptiles have been used to infer daily activity patterns of pterosaurs. The pterosaur genera Pterodactylus, Scaphognathus, and Tupuxuara have been inferred to be diurnal, Ctenochasma, Pterodaustro, and Rhamphorhynchus have been inferred to be nocturnal, and Tapejara has been inferred to be cathemeral, being active throughout the day for short intervals. As a result, the possibly fish-eating Ctenochasma and Rhamphorhynchus may have had similar activity patterns to modern nocturnal seabirds, and the filter-feeding Pterodaustro may have had similar activity patterns to modern anseriform birds that feed at night. The differences between activity patterns of the Solnhofen pterosaurs Ctenochasma, Rhamphorhynchus, Scaphognathus, and Pterodactylus may also indicate niche partitioning between these genera.

Also, unlike fish-eating diurnal raptors will not submerge any part of their body while hunting, preferring only to put their feet into the water, although fish owls will hunt on foot, wading into the shallows. Unlike most owls, the feathers of fish owls are not soft to the touch and they lack the comb and hair-like fringes to the primaries, which allow other owls to fly silently in order to ambush their prey. Due to the lack of these feather-specializations, fish owl wing beats make sounds. The brown fish owl in particular is said to have a noisy wing beat, sometimes described as producing a singing sound, but another description claimed they could be "as silent as any other owl" in flight.

The Ornithocheiromorpha was defined in 2014 by Andres and colleagues, and they made Ornithocheiromorpha the most inclusive clade containing Ornithocheirus, but not Pteranodon. Ornithocheiromorphs are considered to be some of the largest animals to have ever flown. Members of this group are also regarded to have some of the largest pterosaur wingspans, such as the one estimated for the huge Tropeognathus, though still not as large as those estimated for the azhdarchids, which may have reached up to . When ornithocheiromorphs first appeared, they were initially scavengers, consisting in a more terrestrial setting, but their success had made them the top predators of the skies, as well as the most common type of fish-eating pterosaur throughout the early Late Cretaceous.

8Bagwell, William, Director of Agronomy, Callawassie Island, International Society of Arboriculture Certified Arborist Despite the amount of surrounding salt water, Callawassie Island has thirty-three fresh water, man-made lagoons covering . In addition to providing irrigation water for the golf course, these same lagoons enhance the ecology of the island and the surrounding waters by reducing the rainwater run-off into the marsh and providing a source of food for alligators and fish-eating birds. Callawassie has a long history of human occupation. Indians used the surrounding waters for shell fishing and portions of the adjacent land for cultivation. Approximately 275 years ago, Europeans began to significantly impact the ecology of the island primarily through logging most of the pine trees from the interior of the island and later by farming the land.

The sting of many of the smallest cone species may be no worse than that of a bee or hornet sting,Marine wounds and stings but in the case of a few of the larger tropical fish-eating species, especially Conus geographus, Conus tulipa and Conus striatus, a sting can sometimes have fatal consequences. Other dangerous species are Conus pennaceus, Conus textile, Conus aulicus, Conus magus and Conus marmoreus. According to Goldfrank's Toxicologic Emergencies, about 27 human deaths can be confidently attributed to cone snail envenomation, though the actual number is almost certainly much higher; some three dozen people are estimated to have died from geography cone envenomation alone. Most of the cone snails that hunt worms rather than fish are probably not a risk to humans, with the possible exception of larger species.

The previous view that the Megaceryle kingfishers arose in the New World from a specialist fish-eating Alcedinid ancestor which crossed the Bering Strait and gave rise to this genus and the American green kingfishers Chloroceryle, with a large crested species later, in the Pliocene, crossing the Atlantic Ocean to give rise to the giant and crested kingfishers is probably wrong. Rather, it now seems that the genus probably originates in the Old World, possibly Africa, and the ancestor of the belted and ringed kingfishers made the ocean crossing Moyle, Robert G. (2006): "A molecular phylogeny of kingfishers (Alcedinidae) with insights into early biogeographic history". Auk 123(2): 487–499. The Megaceryle kingfishers were formerly placed in Ceryle with the pied kingfisher, but the latter is genetically closer to the American green kingfishers.

At least the latter two features are clear adaptations to aid these owls in capturing fish. Diurnal raptors who feed largely on fish have similar, if not identical, rough texture under their toes, which helps these birds grasp slippery fish. Unlike diurnal raptors who capture fish such as the osprey (Pandion haliaetus) as compared to most terrestrial raptors, the fish owls have large, powerful, and curved talons and a longitudinal sharp keel sitting under the middle claw with all having sharp cutting edges that are very much like those of eagle owls. Also, unlike many fish-eating diurnal raptors, fish owl will not submerge any part of their body while hunting, preferring only to put their feet into the water, although fish owls will hunt on foot, wading into the shallows.

The golden-backed uakari (Cacajao melanocephalus) is endemic to the Negro-Branco moist forests. There are 194 species of mammals, including a few endemic species such as golden-backed uakari (Cacajao melanocephalus), black bearded saki (Chiropotes satanas), Tschudi's slender opossum (Marmosops impavidus), least big-eared bat (Neonycteris pusilla), Guianan spear-nosed bat (Phyllostomus latifolius), Eldorado broad-nosed bat (Platyrrhinus aurarius), Venezuelan fish-eating rat (Neusticomys venezuelae), MacConnell's climbing mouse (Rhipidomys macconnelli), the guinea pig Cavia guianae and Simon's spiny rat (Proechimys simonsi). Common species include South American tapir (Tapirus terrestris), collared peccary (Pecari tajacu), pale-throated sloth (Bradypus tridactylus), long-tailed weasel (Mustela frenata), short-eared dog (Atelocynus microtis), bush dog (Speothos venaticus) and three species of small cats of the Leopardus genus. There are many reptiles and amphibians.

A cladistic analysis by the describers showed Feilongus as the sister taxon of a clade consisting of Gallodactylus and Cycnorhamphus, meaning it was a member of the Gallodactylidae sensu Kellner, a group of ctenochasmatoids, within the larger Archaeopterodactyloidea, the clade containing according to Alexander Kellner the most basal pterodactyloids. The Ctenochasmatoidea are known for having numerous small, thin teeth, possibly for straining food from water, as flamingos do today. However, in 2006 an analysis by Lü Junchang had as outcome that Feilongus was not an archaeopterodactyloid, but a member of the Ornithocheiroidea sensu Kellner, closer to the Anhangueridae. This means that using the alternative terminology of David Unwin they are close to the Ornithocheiroidea sensu Unwin, a group the members of which are typically more adapted to soaring and a piscivore, or fish-eating, diet.

The threatened gharial (Gavialis gangeticus) is a large fish-eating crocodilian that is harmless to humans The main sections of the Ganges River are home to the gharial (Gavialis gangeticus) and mugger crocodile (Crocodylus palustris), and the delta is home to the saltwater crocodile (C. porosus). Among the numerous aquatic and semi- aquatic turtles in the Ganges basin are the northern river terrapin (Batagur baska; only in the lowermost section of the basin), three-striped roofed turtle (B. dhongoka), red-crowned roofed turtle (B. kachuga), black pond turtle (Geoclemys hamiltonii), Brahminy river turtle (Hardella thurjii), Indian black turtle (Melanochelys trijuga), Indian eyed turtle (Morenia petersi), brown roofed turtle (Pangshura smithii), Indian roofed turtle (Pangshura tecta), Indian tent turtle (Pangshura tentoria), Indian flapshell turtle (Lissemys punctata), Indian narrow-headed softshell turtle (Chitra indica), Indian softshell turtle (Nilssonia gangetica), Indian peacock softshell turtle (N.

Freshwater crabs and secondarily frogs seem to be numerical as important, or sometimes more significant, as a source of food as compared to fish for the three smaller fish owl species, other than frogs during spring thus far this has not proven to be the case with the Blakiston's fish owl. The only owl species to which fish are more significant to their diet is the fishing owls of Africa. Blakiston's fish owls seem to co-exist with Steller's sea eagles (Haliaeetus pelagicus) and white-tailed eagles (H. albicilla) on the coasts of the rocky Kurile Islands but nothing is known how they relate with these larger fish-eating raptors, the presence of which has sometimes been theorized as partially the cause of the restricted range of the Blakiston's due to competition for similar food resources.

James Russell explains the toponymy of Arnold's name thus: > "Heron-hald", meaning the corner of the forest where Herons (large birds) > live. Which becomes over the centuries since 500 A.D. by "lazy" > pronunciation, Eron-ald, thence Ern-old and Arn-old. The local topography suggests that Arnold can never have been a haunt of eagles, because they inhabit areas of rocky outcrops, which have formed cliffs: the nearest such location is Creswell Crags, some north-west as the eagle flies. However, the fish-eating white-tailed eagle (also known as the erne) could have caught fish in the River Trent, which lies south-east of Arnold, on the other side of the Mapperley Plains ridge: these eagles might then have flown north-west in the evenings to roost in the ancient woodland area now known as Arnold.

Casts of the vertebrae seen from behind Though no skull remains have been found for Ichthyovenator, all known spinosaurids had elongated, low, narrow snouts that allowed them to reach far for food and to quickly close their jaws in a manner similar to modern crocodilians. The tips of spinosaurids' upper and lower jaws fanned out into a rosette-like shape that bore long teeth, behind which there was a notch in the upper jaw; this formed a natural trap for prey. Like those of other spinosaurids, Ichthyovenators straight, unserrated teeth would have been suitable for impaling and capturing small animals and aquatic prey. This type of jaw and tooth morphology, which is also observed in today's gharials and other fish-eating predators, has led many palaeontologists to believe spinosaurids were largely piscivorous (as implied by Ichthyovenators name).

These freshwater ponds and the planting of cabbage palmettos, live oaks, as well as beneficial bottomland shrubs and trees like red maple and green ash, were designed to lure a wide variety of migrant and indigenous birds, reptiles, and small mammals to the site. For the Baytown Nature Center's watery edges and its inland areas, Crouch Environmental Services and The SWA Group selected flora with high value for wildlife, like nesting areas and food. They also specified plant species like Smooth cordgrass, Sedge, Wiregrass, and live oaks that already thrived in this coastal area. As early as Fall 1995, with just one phase of construction largely completed, deer, fish, crustaceans, and 275 bird species had already appeared in the new wetlands, including two endangered species: the Osprey, a fish-eating hawk, and the three-foot-tall wood stork.

Their quadrate bone articulation with the lower jaw resembled that of a pelican or other birds that can open their beak widely. Altogether, the pseudotooth birds would have filled an ecological niche almost identical to that of the larger fish-eating pteranodontian pterosaurs, whose extinction at the end of the Cretaceous may well have paved the way for the highly successful 50-million-year reign of the Pelagornithidae. Like them as well as modern albatrosses, the pseudotooth birds could have used the system of ocean currents and atmospheric circulation to take round-track routes soaring over the open oceans, returning to breed only every few years. Unlike albatrosses today, which avoid the tropical equatorial currents with their doldrums, Pelagornithidae were found in all sorts of climates, and records from around 40 Ma stretch from Belgium through Togo to the Antarctic.

The floodplain is in the Zambezian flooded grasslands ecoregion, and is bordered by slightly higher sandy ground on which grow dry grasslands (Western Zambezian grasslands) with woodland savanna (Zambezian Baikiaea woodlands) to the east and south, and patches of evergreen forest (Cryptosepalum dry forests) in the north and east. The flood provides aquatic habitats for fish such as tigerfish and bream, crocodiles, hippopotamus, waterbirds, fish-eating birds, and lechwe, the wading antelope. After the flood, the plain is a habitat for grazing animals such as wildebeest, zebra, tsessebe and small antelope such oribi and steenbok, and their predators. These herbivores have been displaced in most areas by the cattle grazed by the Lozi, but they have provided a large game reserve on the dry grassland to the west, the Liuwa Plain National Park, once the Litunga's hunting grounds, established as a game reserve by Lewanika in the 19th century.

The salmon is diadromous, meaning that it changes from a freshwater to a saltwater lifestyle. Many species of flatfish begin their life bilaterally symmetrical, with an eye on either side of the body; but one eye moves to join the other side of the fish – which becomes the upper side – in the adult form. The European eel has a number of metamorphoses, from the larval stage to the leptocephalus stage, then a quick metamorphosis to glass eel at the edge of the continental shelf (eight days for the Japanese eel), two months at the border of fresh and salt water where the glass eel undergoes a quick metamorphosis into elver, then a long stage of growth followed by a more gradual metamorphosis to the migrating phase. In the pre-adult freshwater stage, the eel also has phenotypic plasticity because fish-eating eels develop very wide mandibles, making the head look blunt.

In 1986, Charig and Milner suggested that its elongated snout with many finely serrated teeth indicated that Baryonyx was piscivorous (fish-eating), speculating that it crouched on a riverbank and used its claw to gaff fish out of the water (similar to the modern grizzly bear). Two years earlier, Taquet pointed out that the spinosaurid snouts from Niger were similar to those of the modern gharial and suggested a behaviour similar to herons or storks. In 1987, the Scottish biologist Andrew Kitchener disputed the piscivorous behaviour of Baryonyx and suggested that it would have been a scavenger, using its long neck to feed on the ground, its claws to break into a carcass, and its long snout (with nostrils far back for breathing) for investigating the body cavity. Kitchener argued that Baryonyx jaws and teeth were too weak to kill other dinosaurs and too heavy to catch fish, with too many adaptations for piscivory.

Snout and teeth of NHMUK R3877 shown from the right side and above Based on his 1913 long-jawed reconstruction, Hooley found the beak of Istiodactylus similar to those of birds such as herons, storks, and skimmers, and suggested that Istiodactylus fed on fish, occasionally dipping in water in pursuit of prey. In 1991, the German palaeontologist Peter Wellnhofer compared the front ends of the jaws of Istiodactylus with those of a duck, while noting it was not a "duck-billed pterosaur" (as it has been popularly called), due to its strong teeth. He suggested that the alternately meshing teeth and the broad snout indicated a fish-eating animal. Howse and colleagues found that the distinctive teeth indicated a specialised diet or feeding technique, and instead suggested they could have been used to remove chunks of meat from prey or a carcass in the manner of a "cookie cutter" or by biting and twisting the skull.

Artist's impression of a group of Quetzalcoatlus feeding on the ground There have been a number of different ideas proposed about the lifestyle of Quetzalcoatlus. Because the area of the fossil site was removed from the coastline and there were no indications of large rivers or deep lakes nearby at the end of the Cretaceous, Lawson in 1975 rejected a fish-eating lifestyle, instead suggesting that Quetzalcoatlus scavenged like the marabou stork (which will scavenge, but is more of a terrestrial predator of small animals), but then on the carcasses of titanosaur sauropods such as Alamosaurus. Lawson had found the remains of the giant pterosaur while searching for the bones of this dinosaur, which formed an important part of its ecosystem. In 1996, Lehman and Langston rejected the scavenging hypothesis, pointing out that the lower jaw bent so strongly downwards that even when it closed completely a gap of over remained between it and the upper jaw, very different from the hooked beaks of specialized scavenging birds.

Mautner Schlössl, housing the District Museum, Floridsdorf The Museum of Local History, now known as the District Museum, founded in 1960 in the Floridsdorf Mautner Schlössl (Prague Street) building, is devoted principally to the emergence of the Danube landscape, the beginning of steam navigation, railway history, and the history of some of the more ancient places in the area. The Museum of Harness and Saddlery, Horseshoes and Veterinary Orthopedics, closed in 2014, but pertaining to everything equine, housed a collection of bone specimens, saddles, horse and beef dishes and an exhibit on the development of horseshoeing from the Romans to the present day. The Vienna Fisheries Museum presents its visitors with information on local fishing through the ages, featuring an exhibition of rare specimens of native fish, aquariums, ancient writings and exhibits, fishing gear and fish-eating animals. In Jedlesee, at the former estate of Countess Anna Maria Erdődy, a memorial to Ludwig van Beethoven was established.

Following the landmark High Court Mabo ruling handed down in 1992, which repudiated the prevailing doctrine that Australia had been a terra nullius, and recognized the common law validity of the concept of native title, the Karajarri moved to gather evidence for an application to secure legal acknowledgement and endorsement of their claim to the traditional Karajarri lands. At the same time Western Agricultural Industries (WAI), a private development company, was eyeing the Karajarri lands for the potential their abundant waters offered for establishing a vast irrigation scheme for cotton production, though subsidiary cultivations of sugar cane, leucaena, exotic hardwoods, hemp, viticulture and freshwater aquafarming were also envisaged. The earlier Camballin Irrigation Scheme, implementing similar aims, turned the region immediately to the north of the Karajarri lands into a dustbowl, the toxic wash out of chemical fertilisers leading to drastic losses of local fish-eating species like pelicans and ibis, and the disappearance of kangaroos. The principle of earlier law remains in place: the waters themselves are commonwealth property, and the indigenous peoples have only the right of usufruct.
