The Cottidae are a family of fish in the superfamily Cottoidea, the sculpins. It is the largest sculpin family, with about 275 species in 70 genera. They are referred to simply as cottids to avoid confusion with sculpins of other families.
The eelpouts are the ray-finned fish family Zoarcidae. As the common name suggests, they are somewhat eel-like in appearance. All of the roughly 300 species are marine and mostly bottom-dwelling, some at great depths. Eelpouts are predominantly found in the Northern Hemisphere. The arctic, north pacific and north Atlantic oceans have the highest concentration of species, however species are found around the globe.
The snailfishes or sea snails are a family of marine ray-finned fishes, these fishes make up the Liparidae which is classified within the order Scorpaeniformes.
The Cyclopteridae are a family of marine fishes, commonly known as lumpsuckers or lumpfish, in the order Scorpaeniformes. They are found in the cold waters of the Arctic, North Atlantic, and North Pacific oceans. The greatest number of species are found in the North Pacific. The family name Cyclopteridae derives from the Greek words κύκλος (kyklos), meaning "circle", and πτέρυξ (pteryx), meaning "wing" or "fin", in reference to the circle-shaped pectoral fins of most of the fish in this family.
The Lymantriinae are a subfamily of moths of the family Erebidae. The taxon was erected by George Hampson in 1893.
The fish family Psychrolutidae contains over 35 recognized species in 8 genera. This family consists of bottom-dwelling marine sculpins shaped like tadpoles, with large heads and bodies that taper back into small, flat tails. The skin is loosely attached and movable, and the layer underneath it is gelatinous. The eyes are placed high on the head, focused forward closer to the tip of the snout. Members of the family generally have large, leaf-like pectoral fins and lack scales, although some species are covered with soft spines. This is important to the species as the depths in which they live are highly pressurized and they are ambush/opportunistic/foraging predators that do not expend energy unless they are forced to. The blobfish has a short, broad tongue and conical teeth that are slightly recurved and are arranged in bands in irregular rows along the premaxillaries; canines are completely absent. Teeth are nonexistent on the palatines and vomer; which make up the hard palate. The blobfish also has a set of specialized pharyngeal teeth that are well developed and paired evenly along the upper and lower portions of the pharyngeal arch. These specialized teeth may aid in the breakdown of food due to the very strategic dependency on whatever food falls from above.
Stichaeidae, the pricklebacks or shannies, are a family of marine ray-finned fishes in the suborder Zoarcoidei of the order Scorpaeniformes. Most species are found in the North Pacific Ocean with a few in the North Atlantic Ocean.
Paraliparis is a genus of fish in the family Liparidae, the snailfishes. It is found in benthic, benthopelagic and pelagic habitats in all the world's oceans.
Paraliparis membranaceus is a species of snailfish only known from a single specimen of 57 mm standard length collected in Sarmiento Channel in the fjordlands of southern Chile.
Careproctus is a genus of snailfishes found in benthic and benthopelagic habitats in the Atlantic, Pacific, Arctic and Southern Oceans. Whether they truly are absent from the Indian Ocean is unknown and might be an artifact of limited sampling. They range from shallow coastal seas in the far north of their range to the abyssal zone, at depths of 6 to 5,459 m (20–17,910 ft). In the Northern Hemisphere they mostly live shallower than Paraliparis, but this pattern is reversed in the Southern Hemisphere. Although almost entirely restricted to very cold waters, a single species, C. hyaleius, lives at hydrothermal vents.
Liparis fabricii, commonly known as the gelatinous seasnail or gelatinous snailfish, is a benthopelagic species of snailfish from the Arctic Ocean. It has a tadpole-like body with a maximum length of about 20 cm (7.9 in). It is brown to black in coloration with a distinctive dark peritoneum. It preys on small crustaceans and marine worms. It is not commercially important, though it is a valuable food source for predatory fish and seabirds in the Arctic region.
Anatoly Petrovich Andriyashev was a Soviet and Russian ichthyologist, marine biologist, and zoogeographist, notable for his studies of marine fauna of the Arctic and the Northern Pacific.
Acantholiparis is a genus of marine ray-finned fishes belongong to the family Liparidae, the snailfishes. These fishes are found in the northern Pacific Ocean.
Crystallichthys is a genus of marine ray-finned fishes belonging to the family Liparidae, the snailfishes. These fishes are found in the northern Pacific Ocean.
Liparis atlanticus, the Atlantic snailfish or Atlantic seasnail, is a species of marine ray-finned fish belonging to the family Liparidae, the snailfishes. This species is found in the western Atlantic Ocean off the eastern coast of North America.
Liparis marmoratus, or the festive snailfish, is a marine ray-finned fish from the genus Liparis. It was first described by Schmidt in 1950.
Liparis alboventer is a species of marine ray-finned fish belonging to the family Liparidae, the snailfishes The species was originally described Careproctus alboventer by Zoya Valentinovna Krasyukova in 1984. Very little is known about the fish except from the type specimens caught. It may be found in marine habitats at ten degrees Celsius in the South Kuril Strait of the Northwest Pacific.
Lycodes is a genus of zoarcid fish in the subfamily Lycodinae. It is the most species-rich genus in its taxonomic family as well as in the Arctic Ocean and adjacent waters. They occupy both shallow waters and deeper waters down to 3000 meters. A few species can occur in brackish waters.
Cottinae is a subfamily of ray-finned fishes belonging to the family Cottidae, the typical sculpins. The subfamily has species throughout the northern hemisphere in both marine and freshwater habitats.
Cyclopteroidea is a superfamily of ray-finned fishes within the order Scorpaeniformes. The superfamily comprises 2 families, the Cyclopteridae, the lumpsuckers, of the cool northern seas and the widespread Liparidae, the snailfishes. A common feature shared by these families is that they typically have the pelvic fins modified to form a disc shaped sucker.
