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 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.
Cottus is a genus of the mainly freshwater ray-finned fishes belonging to the family Cottidae, the typical sculpins. They are often referred to as the "freshwater sculpins", as they are the principal genus of sculpins to be found in fresh water. They are native to the Palearctic and Nearctic.
The scaled sculpins, Icelus, are a genus of marine ray-finned fishes belonging to the family Cottidae, the typical sculpins. Most of the fishes in this genus are found in the northern Pacific Ocean but they also occur in the North Atlantic Ocean.
Clinocottus globiceps, the mosshead sculpin or globe-headed sculpin, is a species of marine ray-finned fish belonging to the family Cottidae, the typical sculpins. This sculpin is found in the northeastern Pacific.
Clinocottus is a genus of marine ray-finned fishes belonging to the family Cottidae, the typical sculpins. They are nearshore benthic fishes native to the northeastern Pacific Ocean. They are mentioned as sharpnose sculpins.
Clinocottus acuticeps, the sharpnose sculpin, is a species of marine ray-finned fish belonging to the family Cottidae, the typical sculpins. This sculpin is found in the eastern Pacific Ocean.
The Andriyashev largeheaded sculpin is a species of marine ray-finned fish belonging to the family Cottidae, the typical sculpins. This species is found in the northwestern Pacific Ocean. This monospecific genus, and therefore this species, are known from a single specimen, the holotype. This was collected from off Simushir Island in the Kuril Islands at a depth of 100 metres (330 ft). That specimen had a total length of 23.6 cm (9.3 in) long. FishBase classifies this taxon within the Cottidae but other authorities classify it within the subfamily Psychrolutinae of the family Psychrolutidae. The genus name Andriashevicottus includes a patronym, the person honoured was not identified by the describer Fedorov, however, it is almost certainly the Soviet ichthyologist Anatoly Petrovich Andriashev, the patronym is suffixed with Cottus, the type genus of the family Cottidae. The specific name megacephalus means "big head".
Artediellus is a genus of marine ray-finned fishes belonging to the family Cottidae, the typical sculpins. Most of the fishes in this genus are found in the northern Pacific Ocean but they also occur in the Arctic and North Atlantic Oceans.
