Ateleopodidae
The jellynose fishes or tadpole fishes are the small order Ateleopodiformes. This group of ray-finned fish is monotypic, containing a single family Ateleopodidae. It has about a dozen species in four genera, but these enigmatic fishes are in need of taxonomic revision. The scientific name means "''Ateleopus''-shaped", from ''Ateleopus'' (the type genus) + the standard fish order suffix "-formes". It ultimately derives from Ancient Greek ''atelēs'' (ἀτελής, "imperfect") + ''pous'' (πούς, "foot") + Latin ''forma'' ("external form"), the Greek part in reference to the reduced pectoral and ventral fins of the jellynoses. Description and ecology Jellynoses are deep-water, bottom-dwelling, marine fishes. They are known from the Caribbean Sea, eastern Atlantic, the western and central Indopacific, and the Pacific coast of Central America.Olney (1998), Nelson (2006): p.213 Their skeletons are largely cartilage (hence "jellynose"), although they are true teleosts and ...

Guentherus
''Guentherus'' is a genus of jellynose fishes, belonging to the Ateleopodidae family, with two recognized species: * ''Guentherus altivela'' Balthazar Osório, Osório, 1917 (jellynose, highfin tadpole fish) * ''Guentherus katoi'' Hiroshi Senou, Senou, Shinji Kuwayama, Kuwayama & Koichi Hirate, Hirate, 2008 The genus distinguishes itself from others in its family because of discrepancies in morphology. ''Guentherus'' has "3 free rays followed by 6–9 normal rays with membrane between them in the pelvic fins." Other genera in this family have "a single long filament or 1 relatively developed ray plus 0 to 3 rudimentary rays." , Family: Ateleopodidae The family Ateleopodidae is made up of four genera and within that thirteen species: Ateleopus, Ijimaia, Parateleopus, ''Guentherus''. Ateleopodids are located primarily near tropical and subtropical waters; with Ateleopus, Parateleopus, and ''Guentherus'' located in the Pacific and Ijimaia located in the Atlantic.

Ateleopus
''Ateleopus'' is a genus of ray-finned fish in the jellynose family Ateleopodidae. It is the type genus of its family, and the order Ateleopodiformes. For some time, it was known as ''Podateles'', because ''Ateleopus'' had been used to replace the frog genus name ''Atelopus'', which was deemed to be a spelling error. This was mistaken, however, and the fish and frog genera reverted to their original names. This genus occurs in the fossil record since the mid-Miocene. Species There are currently 4 recognized species in this genus. Several other species have been described, but these are synonyms.Kaga, T., Van Oijen, M.J.P., Kubo, Y. & Kitagawa, E.

Teleost
Teleostei (; Greek ''teleios'' "complete" + ''osteon'' "bone"), members of which are known as teleosts ), is, by far, the largest infraclass in the class Actinopterygii, the ray-finned fishes, containing 96% of all extant species of fish. Teleosts are arranged into about 40 orders and 448 family (biology), families. Over 26,000 species have been described. Teleosts range from giant oarfish measuring or more, and ocean sunfish weighing over , to the minute male anglerfish ''Photocorynus spiniceps'', just long. Including not only torpedo-shaped fish built for speed, teleosts can be flattened vertically or horizontally, be elongated cylinders or take specialised shapes as in anglerfish and seahorses. The difference between teleosts and other bony fish lies mainly in their jaw bones; teleosts have a movable premaxilla and corresponding modifications in the jaw musculature which make it possible for them to cranial kinesis, protrude their jaws outwards from the mouth.

Anal Fin
Fins are distinctive anatomical features composed of bony spines or rays protruding from the body of a fish. They are covered with skin and joined together either in a webbed fashion, as seen in most bony fish, or similar to a flipper, as seen in sharks. Apart from the tail or caudal fin, fish fins have no direct connection with the spine and are supported only by muscles. Their principal function is to help the fish swim. Fins located in different places on the fish serve different purposes such as moving forward, turning, keeping an upright position or stopping. Most fish use fins when swimming, flying fish use pectoral fins for gliding, and frogfish use them for crawling. Fins can also be used for other purposes; male sharks and mosquitofish use a modified fin to deliver sperm, thresher sharks use their caudal fin to stun prey, reef stonefish have spines in their dorsal fins that inject venom, anglerfish use the first spine of their dorsal fin like a fishing rod to lu ...

Chondrichthyes
Chondrichthyes (; ) is a class that contains the cartilaginous fishes that have skeletons primarily composed of cartilage. They can be contrasted with the Osteichthyes or ''bony fishes'', which have skeletons primarily composed of bone tissue. Chondrichthyes are jawed vertebrates with paired fins, paired nares, scales, and a heart with its chambers in series. Extant chondrichthyes range in size from the 10 cm (3.9 in) finless sleeper ray to the 10 m (32 ft) whale shark. The class is divided into two subclasses: Elasmobranchii (sharks, rays, skates, and sawfish) and Holocephali ( chimaeras, sometimes called ghost sharks, which are sometimes separated into their own class). Within the infraphylum Gnathostomata, cartilaginous fishes are distinct from all other jawed vertebrates. Anatomy Skeleton The skeleton is cartilaginous. The notochord is gradually replaced by a vertebral column during development, except in Holocephali, where the notochord stays intact. In some deepwat ...

Cartilage
Cartilage is a resilient and smooth type of connective tissue. In tetrapods, it covers and protects the ends of long bones at the joints as articular cartilage, and is a structural component of many body parts including the rib cage, the neck and the bronchial tubes, and the intervertebral discs. In other taxa, such as chondrichthyans, but also in cyclostomes, it may constitute a much greater proportion of the skeleton. It is not as hard and rigid as bone, but it is much stiffer and much less flexible than muscle. The matrix of cartilage is made up of glycosaminoglycans, proteoglycans, collagen fibers and, sometimes, elastin. Because of its rigidity, cartilage often serves the purpose of holding tubes open in the body. Examples include the rings of the trachea, such as the cricoid cartilage and carina. Cartilage is composed of specialized cells called chondrocytes that produce a large amount of collagenous extracellular matrix, abundant ground substance that is rich in pro ...
