The tiger tail sea horse lives in Western Central Pacific: Malaysia, Singapore, Thailand, Vietnam, and the Philippines. It lives from 0-1.5 years in captivity and in the wild, 1–5 years. It is harmless. Its climate in water is tropical; 15°N - 1°N and Its maximum size is 18.7 cm. Its snout is 2.2"
"Hagfish Hagfish, the class Myxini (also known as Hyperotreti), are eel-shaped, slime-producing marine fish (occasionally called slime eels). They are the only known living animals that have a skull but no vertebral column, although hagfish do have rudimentary vertebrae. Along with lampreys, hagfish are jawless; they are the sister group to jawed vertebrates, and living hagfish remain similar to hagfish from around 300 million years ago. The classification of hagfish had been controversial. The issue was whether the hagfish was a degenerate type of vertebrate-fish that through evolution had lost its vertebrae (the original scheme) and was most closely related"

It has four hearts, two brains, and a paddle-like tail. Cartilaginous fish have a cartilaginous skeleton. However, their ancestors were bony animals, and were the first fish to develop paired fins. Cartilaginous fish don't have swim bladders. Their skin is covered in placoid scales ""(dermal denticles)"" that are as rough as sandpaper. Because cartilaginous fish do not have bone marrow, the spleen and special tissue around the gonads produces"

The largest confirmed individual had a length of and a weight of about . The whale shark holds many records for size in the animal kingdom, most notably being by far the largest living nonmammalian vertebrate. It is the sole member of the genus Rhincodon and the only extant member of the family Rhincodontidae which belongs to the subclass Elasmobranchii in the class Chondrichthyes. Before 1984 it was classified as ""Rhiniodon"" into Rhinodontidae. The whale shark is found in open"

Some fish, e.g. the spotted ratfish (""Hydrolagus colliei"") and batiform fish (electric rays, sawfishes, guitarfishes, skates and stingrays) use their pectoral fins as the primary means of locomotion, sometimes termed labriform swimming. Marine mammals oscillate their body in an up-and-down (dorso-ventral) direction. Other animals, e.g. penguins, diving ducks, move underwater in a manner which has been termed ""aquatic flying"". Some fish propel themselves without a wave motion of the body, as in the slow-moving seahorses and ""Gymnotus""."
"Molidae The Molidae comprise the family of the molas or ocean sunfishes, unusual fish whose bodies come to an end just behind the dorsal and anal fins, giving them a ""half-fish"" appearance. They are also the largest of the ray-finned bony fish, with the ocean sunfish ""Mola mola"" and southern sunfish, ""Mola alexandrini"", both recorded at up to in length and in weight. Molidae have the fewest vertebrae of any fish, with only 16 in ""Mola mola"". They also completely lack all caudal bones, and most of their skeletons are made of cartilage. No bony plates occur in the skin,"

"Atlantic tarpon The Atlantic tarpon (""Megalops atlanticus"") is a ray-finned fish which inhabits coastal waters, estuaries, lagoons, and rivers. Tarpons feed almost exclusively on schooling fish, shrimp and occasionally crabs. A tarpon is capable of filling its swim bladder with air, like a primitive lung. This gives the tarpon a predatory advantage when oxygen levels in the water are low. Tarpons have been recorded at up to in length and weighing up to . The Atlantic tarpon is also known as the silver king. In appearance, tarpons are greenish or bluish on top and silver on the sides. The large"

Pineapplefish The pineapplefish (""Cleidopus gloriamaris"") is a species of fish in the family Monocentridae, and the sole member of its genus. It is also known as the knightfish or the coat-of-mail fish, due to the armor-like scales covering its body, and the port-and-starboard light fish, as it has a pair of bioluminescent organs that are reminiscent of navigation lights on ships. Its specific epithet is from the Latin ""gloria"" and ""maris"", meaning ""glory of the sea"". The pineapplefish is native"
"Fish Fish are gill-bearing aquatic craniate animals that lack limbs with digits. They form a sister group to the tunicates, together forming the olfactores. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups. Tetrapods emerged within lobe-finned fishes, so cladistically they are fish as well. However, traditionally fish are rendered paraphyletic by excluding the tetrapods (i.e., the amphibians, reptiles, birds and mammals which all descended from within the same ancestry). Because in this manner the term ""fish"" is defined negatively as a paraphyletic group, it is not considered"
"Tiktaalik Tiktaalik is a monospecific genus of extinct sarcopterygian (lobe-finned fish) from the late Devonian period, about 375 MYA (million years ago), having many features akin to those of tetrapods (four-legged animals). Unearthed in Arctic Canada, Tiktaalik is technically a fish, complete with scales and gills - but it has the flattened head of a crocodile and unusual fins. Its fins have thin ray bones for paddling like most fishes', but they also have sturdy interior bones that would have allowed Tiktaalik to prop itself up in shallow water and use its limbs for support as most four-legged animals do."
"and using pectoral fins (located behind their eyes) to steer. The slowest-moving fish in the world is ""H. zosterae"" (the dwarf seahorse), with a top speed of about per hour. Since they are poor swimmers, they are most likely to be found resting with their prehensile tails wound around a stationary object. They have long snouts, which they use to suck up food, and their eyes can move independently of each other like those of a chameleon. Anatomical evidence, supported by molecular, physical, and genetic evidence, demonstrates seahorses are highly modified pipefish. The fossil record of seahorses, however, is very"

Unlike groupings such as birds or mammals, fish are not a single clade but a paraphyletic collection of taxa, including jawless, cartilaginous and skeletal types. Jawless fish were the earliest fish to evolve. There is current debate over whether these are really fish at all. They have no jaw, no scales, no paired fins, and no bony skeleton. Their skin is smooth and soft to the touch, and they"
"Monognathus Monognathus, or onejaw, is the only genus of the family Monognathidae of deep-sea, eel-like fishes. The name comes from the Greek ""monos"" meaning “one” and ""gnathos"" meaning “jaw”, a reference to the large mouth in comparison with the rest of the fish, and also the absence of an upper jaw (maxilla and premaxilla bones are absent). The dorsal and anal fins lack bony supports and the pectoral fins are missing. The snout has a fang which is connected to glands. Typical lengths are from 4 to 10 cm (1.5–4 in), the maximum length recorded is 15.9 cm (6.3 in)."
"Poacher (fish) The poachers are a family (Agonidae) of small, bottom-dwelling, cold-water marine fish. They are also known as alligatorfishes, starsnouts, hooknoses, and rockheads. Poachers are notable for having elongated bodies covered by scales modified into bony plates, and for using their large pectoral fins to move in short bursts. The family includes about 47 species in some 20 genera, some of which are quite widespread. The pelvic fins are nearly vestigial, typically consisting of one small spine and a few rays. The swim bladder is not present. At in length, the dragon poacher ""Percis japonica"" is the largest member"

They possess no pelvic fins, and many species also lack pectoral fins. The dorsal and anal fins are fused with the caudal fin, forming a single ribbon running along much of the length of the animal. Eels swim by generating body waves which travel the length of their bodies. They can swim backwards by reversing the direction of the wave. Most eels live in the shallow waters of the ocean"
"Taillight shark The taillight shark (""Euprotomicroides zantedeschia"") is a little-known species of shark in the family Dalatiidae and the only member of its genus. It is known from only four specimens collected from deep oceanic waters in the southern Atlantic Ocean and Pacific Ocean. A small shark with a laterally compressed body and a bulbous snout, this species has unusual adaptations that indicate a specialized lifestyle: its pectoral fins are paddle-like and may be used for propulsion, unlike other sharks and it has a pouch-like gland on its abdomen that emits clouds of luminescent blue fluid. This shark is likely"

The bowfin is the only species to survive today, although additional species in all four subfamilies of Amiidae are known from Jurassic, Cretaceous, and Eocene fossils. Bowfins are now found throughout eastern North America, typically in slow-moving backwaters, canals, and ox-bow lakes. When the oxygen level is low (as often happens in still waters), the bowfin can rise to the surface and gulp air into its swim bladder, which is lined with blood vessels and can serve as a primitive lung. The family is divided into four subfamilies, with 11"

". Snakes are also taken occasionally, especially partially aquatic ones, as are amphibians and crustaceans (largely crayfish and crabs). To hunt fish, the eagle swoops down over the water and snatches the fish out of the water with its talons. They eat by holding the fish in one claw and tearing the flesh with the other. Eagles have structures on their toes called spicules that allow them to grasp fish. Osprey also have this adaptation. Bald eagles have powerful talons and have been recorded flying with a mule deer (""Odocoileus hemionus"") fawn. This feat is the record for the heaviest"
