Cottunculus is a genus of marine ray-finned fish belonging to the family Psychrolutidae. These fishes are found in the Atlantic, Pacific and Arctic oceans.
There are currently 6 recognized species in this genus: [2]
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.
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.
Antipodocottus is a genus of marine ray-finned fishes belonging to the family Cottidae, the typical sculpins. These fishes are found in the western Pacific Ocean. This is the only genus of Cottids represented in the Southern Hemisphere, although their classification in the Cottidae is not universally accepted.
The pale toadfish is a fathead sculpin of the family Psychrolutidae, found on the continental shelf around New Zealand, between 250 and 1,000 metres deep. It is up to 30 cm long.
The frilled toadfish is a fathead sculpin of the family Psychrolutidae, found on the continental shelf around Australia's Macquarie Island.
Myoxocephalus is a genus of marine ray-finned fishes belonging to the family Cottidae, the typical sculpins. They are found in the norther Pacific, Arctic and Atlantic Oceans, with a few species in lakes.
Psychrolutes is a genus of fish of the family Psychrolutidae. Though found predominantly in the deep sea, a handful of species are present in the intertidal regions of the North Pacific rim. In June 2003, During the NORFANZ Expedition north-west of New Zealand, scientists trawled a specimen of P. microporos at a depth between 1,013 metres (3,323 ft) and 1,340 metres (4,400 ft) on the Norfolk Ridge.
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.
Archistes is a genus of marine ray-finned fishes belonging to the family Cottidae, the typical sculpins. the two species in this genus are found in the northern Pacific Ocean.
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.
Gymnocanthus is a genus of marine ray-finned fishes belonging to the family Cottidae, the typical sculpins. These fishes are found in the northern Pacific, Arctic and northern Atlantic Oceans.
Oligocottus is a genus of marine ray-finned fishes belonging to the family Cottidae, the typical sculpins. These sculpins are found in the northern and eastern Pacific Ocean.
Radulinus is a genus of marine ray-finned fishes belonging to the family Cottidae, the typical sculpins. These fishes are found in the eastern Pacific Ocean.
Triglops is a genus of marine ray-finned fishes belonging to the family Cottidae, the typical sculpins. These fishes are found in the North Pacific, Arctic and North Atlantic Oceans.
Malacocottus is a genus of fatheads native to the northern Pacific Ocean. Malacocottus are typically occupied in the benthic zone near the bottom of the northern Pacific Ocean.
Cottunculus microps, the polar sculpin, is a species of fathead sculpin, a deepwater fish found in the North Atlantic and Arctic Oceans. It was first described in 1875 by the Norwegian zoologist Robert Collett, curator of the Natural History Museum at the University of Oslo.
The pallid sculpin is a species of fish in the family Psychrolutidae (blobfishes).
The spinynose sculpin is a species of marine ray-finned fish belonging to the family Cottidae, the typical sculpins. It is found in the northeastern Pacific Ocean from Alaska south to Washington and the San Juan Islands. The spinynose sculpin is the only species in the monospecific genus Asemichthys. This sculpin lays its eggs on the egg masses of the buffalo sculpin, thought to be a strategy to take advantage of the larger fish’s egg guarding behaviour.
Cottunculus spinosus is a species of fish in the family Psychrolutidae (blobfishes) found in the Southeast Atlantic Ocean.
Cottunculus tubulosus is a species of fish in the family Psychrolutidae (blobfishes) found in the Northeast Atlantic Ocean.
