Fish of the order are found in oceans worldwide, at depths from 120 to 4,900 metres (390 to 16,080 ft). They are elongated fish, although not as much so as the true eels , and have various feeding strategies, like hyperbenthic and detritus feeders, epifaunal browsers, and megafaunal croppers. [ 3 ]
Common names of fish can refer to a single species; to an entire group of species, such as a genus or family; or to multiple unrelated species or groups.Ambiguous common names are accompanied by their possible meanings.
This is a list of fish with common names that are based on the names of other animals. The names listed here may refer to single species, broader taxa ( genera , families ), or assortments of types. Where names are ambiguous, the various meanings should be listed here.
Spiny sharks (extinct) were the earliest known jawed fish. They resembled sharks and were ancestral to them. Spiny sharks, class Acanthodii, are extinct fish that share features with both bony and cartilaginous fish, though ultimately more closely related to and ancestral to the latter. Despite being called "spiny sharks", acanthodians predate ...
Some marine fish, like sharks, have adopted a different, efficient mechanism to conserve water, i.e., osmoregulation. They retain urea in their blood in relatively higher concentration. Urea is damaging to living tissue so, to cope with this problem, some fish retain trimethylamine oxide. This provides a better solution to urea's toxicity.
The Anguillidae are a family of ray-finned fish that contains the freshwater eels.They are the only modern taxon of the infraorder Anguillales.All the extant species and six subspecies in this family are in the genus Anguilla, and are elongated fish of snake-like bodies, with long dorsal, caudal and anal fins forming a continuous fringe.
Halosaurs are eel-shaped fishes found only at great ocean depths. As the family Halosauridae, halosaurs are one of two families within the order Notacanthiformes; the other being the deep-sea spiny eels, Notacanthidae. Halosaurs are thought to have a worldwide distribution, with some 17 species in three genera represented.
The gap saw the demise of the Devonian fish-like ichthyostegalian labyrinthodonts, and the rise of the more advanced temnospondyl and reptiliomorphan amphibians that so typify the Carboniferous terrestrial vertebrate fauna. The Carboniferous seas were inhabited by many fish, mainly Elasmobranchs (sharks and their relatives).
