Snailfish are Scorpaeniform Marine fish
Snailfish are Scorpaeniform Marine fish of the family Liparidae. Widely distributed from the Arctic to Antarctic Oceans including the northern Pacific. The snailfish family contains 30 genera and 361 species...
They are closely related to the sculpins of the family Cottidae and the lumpfish of the family Cyclopteridae. Snailfish are sometimes included within the latter family...
The snailfish family is poorly studied and few specifics are known. Their elongate, tadpole-like bodies are similar in profile to the rattails. Their heads are large with small eyes; their bodies are slender to deep, tapering to a very small tail. The extensive dorsal and anal fins may merge or nearly merge with the tail fin...
Snailfish are scaleless with a thin, loose gelatinous skin; some species, such as the spiny snailfish (Acantholiparis opercularis) have prickly spines as well. Their teeth are small and simple with blunt cusps. The deep-sea species have prominent, well-developed sensory pores of the head, part of the animals' lateral line system...
The pectoral fins are large and provide the snailfish with its primary means of locomotion. They are benthic fish with pelvic fins modified to form an adhesive disc; this nearly circular disc is absent in Paraliparis and Nectoliparis species. Snailfish range in size from Paraliparis australis at 5 centimetres (2.0 in) to Polypera simushirae at some 77 centimetres (30 in) in length. The latter species may reach a weight of 11 kilograms (24 lb), but most species are toward the smaller end of this range. Snailfish are of no interest to commercial fisheries...
