A sculpin is a type of fish that belongs to the superfamily Cottoidea in the order Scorpaeniformes. As of 2006, this superfamily contains 7 families, 94 genera, and 387 species.
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.
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.
The dark toadfish is a species of marine ray-finned fish belonging to the family Psychrolutidae, the fatheads and toadfishes. This fish is found on the continental shelf around New Zealand.
The frilled toadfish is a fathead sculpin of the family Psychrolutidae, found on the continental shelf around Australia's Macquarie Island.
Psychrolutes is a genus of marine ray-finned fishes belonging to the family Psychrolutidae, the fatheads and toadfishes. 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.
Bathylutichthys a genus of marine ray-finned fishes which is the only genus in the monotypic family Bathylutichthyidae, known as the Antarctic sculpins. These fishes are found in the Southern Ocean.
Toadfish is the common name for a variety of species from several different families of fish, usually because of their toad-like appearance. Dogfish is a name for certain species along the gulf coast.
Psychrolutes microporos is a species of deepwater marine fish in the family Psychrolutidae, commonly known as a blobfish or fathead. It is found in the abyssal zone in waters around Australia and New Zealand. A photograph of an individual taken in 2003 has become famous on the internet.
Joseph (Joe) Schieser Nelson was an Canadian ichthyologist. He is best known for the book Fishes of the World, which is the standard reference in fish systematics and evolution.
Ambophthalmos is a genus of marine ray-finned fish belonging to the family Psychrolutidae. These fishes are found in the southwestern Pacific Ocean.
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.
The spinyhead sculpin is a species of marine ray-finned fish belonging to the family Psychrolutidae, the fatheads. This species is found in the northern Pacific Ocean. This species is the only species in the monospecific genus Dasycottus.
Eurymen is a small genus of marine ray-finned fishes belonging to the family Psychrolutidae, the fatheads. These fishes are found in the northern Pacific Ocean.
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.
Neophrynichthys is a small genus of marine ray-finned fishes belonging to the family Psychrolutidae, the fatheads. These fishes are found in the southwestern Pacific Ocean waters around New Zealand.
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 nudus, the bonyskull toadfish, is a species of fish in the family Psychrolutidae (blobfishes) found in the Southwest Pacific Ocean off New Zealand at depths down to 1,123 m (3,684 ft).
