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. Along with that,the Cyclopteridae is known for its beauty and power.
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.
Monacoa grimaldii, also known as the mirrorbelly, barreleye, Grimaldi's barreleye, and flatiron fish, is a species of fish in the family Opisthoproctidae. Different sources express different views on its distribution. According to Poulsen and colleagues, it is known with certainty only from the Atlantic Ocean, with records from the Pacific Ocean representing other Monacoa species. However, FishBase and Catalog of Fishes include the Pacific, and in the case of the latter, the Indian Ocean in its range. It is typically mesopelagic, but it has been recorded from depths of 0 to 4,750 metres. It has a body length of 8 cm (3.1 in) SL.
The Alaska pollock or walleye pollock is a marine fish species of the cod genus Gadus and family Gadidae.
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.
Opisthoproctus soleatus is a species of fish in the family Opisthoproctidae. It was first described in 1888 by Léon Vaillant. The species lives in most tropical seas, but is more common in the eastern Atlantic, from western Ireland to Mauritania and from Sierra Leone to Angola, and also in the South China Sea. O. soleatus can grow to a standard length of 10.5 centimetres (4.1 in) and usually live from about 500 to 700 metres deep.
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.
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.
Myctophum punctatum is a species of mesopelagic fish in the family Myctophidae. Its common name is spotted lanternfish, sometimes spelled spotted lanterfish. It is found in the Northern Atlantic and in the Mediterranean at depths down to 1000m. It is one of the dominant species in midwater assemblages near the Mid-Atlantic Ridge.
Monacoa is a genus of fish in the family Opisthoproctidae found in Atlantic and Pacific Oceans. They are also known as long-nosed mirrorbellies or simply mirrorbellies, in reference to the bioluminescent organ in their intestines. The largest species, Monacoa grimaldii, can grow to 8 cm (3.1 in) standard length.
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.
Psychrolutes inermis is a species of marine ray-finned fish belonging to the family Psychrolutidae, the fatheads. This is a bathydemersal fish which is found in the eastern Atlantic from Mauritania south to the southwestern Indian Ocean from South Africa and Mozambique. It has been recorded at depths from 550 to 1,550 m.
Lampadena speculigera is a species of lanternfish in the subfamily Lampanyctinae. It is a mesopelagic fish that is found in the Atlantic, Indian, and Pacific Oceans. Its vernacular name is mirror lanternfish.
The pallid sculpin is a species of fish in the family Psychrolutidae (blobfishes).
Cottunculus spinosus is a species of fish in the family Psychrolutidae (blobfishes) found in the Southeast Atlantic Ocean.
Cottunculus granulosus is a species of fish in the family Psychrolutidae (blobfishes) found in the Southwest 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).
Cottunculus sadko is a species of marine ray-finned fish belonging to the family Psychrolutidae, the fatheads. This species is found from Greenland to the Norwegian and Kara Seas in the northeast Atlantic Ocean. However, some authorities regard this taxon as a synonym of the Polar sculpin.
