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.
There are currently two 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.
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.
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.
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.
Astrocottus is a genus of marine ray-finned fishes belonging to the family Cottidae, the typical sculpins. These fishes are found in the northwestern Pacific Ocean.
Bero elegans 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 species grows to a length of 20 centimetres (7.9 in) TL. It is the only known member of the genus Bero.
Bolinia is a monospecific genus of marine ray-finned fish belonging to the family Cottidae, the typical sculpins. This taxon is endemic to the northern Pacific Ocean around the Aleutian Islands of Amukta, Carlisle, and Semisopochnoi. It is found at depths of between 201 to 410 metres. This species grows to a length of 18.9 centimetres (7.4 in) SL. The only species in the genus is Bolinia euryptera.
Furcina is a small genus of marine ray-finned fishes belonging to the family Cottidae, the typical sculpins. This species is found in the northwestern Pacific Ocean from around Japan and the Republic of Korea.
Pseudoblennius is a genus of marine ray-finned fishes belonging to the family Cottidae, the typical sculpins. These fishes are found in the northwestern Pacific Ocean.
Stelgistrum is a genus of marine ray-finned fishes belonging to the family Cottidae, the typical sculpins. These fishes are found in the northern Pacific Ocean.
The sponge sculpin is a species of marine ray-finned fish belonging to the family Cottidae, the typical sculpins. It is the only species in the monospecific genus Thyriscus. This fish is found in the northern Pacific Ocean where it is found at depths from 100 to 800 m though usually in the range of 300 to 400 m. This species grows to a maximum published total length of 14.5 cm (5.7 in).
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.
Ebinania is a genus of marine ray-finned fishes belonging to the family Psychrolutidae, the fatheads. These fishes are found in the Southern, Indian, Pacific and Atlantic Oceans.
Gilbertidia is a genus of marine ray-finned fishes belonging to the family Psychrolutidae, the fatheads and toadfishes. 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.
