Hypsagoninae is a subfamily of marine ray-finned fishes belonging to the family Agonidae, part of the sculpin superfamily Cottoidea. These fishes are found in the North Pacific Ocean. [2]
Hypsagoninae was first proposed as a taxonomic grouping in 1861 by the American zoologist Theodore Gill. Some workers have regarded the genus Agonomalus as synonymous with Hypsagonus and place the two remaining genera in the subfamily Percidinae which was also named by Gill in 1897. [1] However, most authorities recognise the three genera and place them in the subfamily Hypsagoninae. [3] The 5th editiuon of Fishes of the World classifies the Hypsagoninae within the family Agonidae, part of the superfamily Cottoidea, the sculpins. [2]
Hypsagoninae contains following 3 genera: [4]
Hypsagoninae sculpins typically have deep, laterally compressed bodies with a termional mouth which has nearly equal jaws, The rear edge of the orbit is convex. The bony plates on the body are arranged in groups and rows which are bot clearly distinct and do not have exact margins and are made up of plates that differ in size and shape. There are plates on the first dorsal fin and the pectoral fin and there is no enlarged plate on the snout. The first dorsal fin is supported by strong spines. [3] The smallest species is the kelp poacher (Agonomalus mozinoi) which has a maximum published total length of 8.9 cm (3.5 in) while the largest is the dragon poacher (Percis japonica) ith a maximum published total length of 42 cm (17 in). [5]
Hypsagoninae sculpins are found in the northern Pacific Ocean from Japan north to the Chukchi Sea and south to California. [3]
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 Scorpaeniformes are a diverse order of ray-finned fish, including the lionfishes and sculpins, but have also been called the Scleroparei. It is one of the five largest orders of bony fishes by number of species, with over 1,320.
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.
Agonidae is a family of small, bottom-dwelling, cold-water marine fish. Common names for members of this family include poachers, Irish lords, sea ravens, alligatorfishes, starsnouts, hooknoses, and rockheads. They are notable for having elongated bodies covered by scales modified into bony plates, and for using their large pectoral fins to move in short bursts. The family includes about 59 species in some 25 genera, some of which are quite widespread.
Rhamphocottidae is a family of ray-finned fishes belonging to the superfamily Cottoidea, the sculpins. The species in this family occur in the North Pacific Ocean.
Hexagrammidae, the greenlings, is a family of marine ray-finned fishes belonging to the suborder Cottoidei in the order Scorpaeniformes. These fishes are found in the North Pacific Ocean.
The Hemitripterinae is a subfamily of the scorpaeniform family Agonidae, known as sea ravens or sailfin sculpins. They are bottom-dwelling fish that feed on small invertebrates, found in the northwest Atlantic and north Pacific Oceans. They are covered in small spines.
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.
Bothragonus is a genus of marine ray-finned fishes belonging to the family Agonidae, the poachers and related fishes. It is the only genus in monotypic subfamily Bothragoninae. These fishes are found in the northern Pacific Ocean.
Hemilepidotus, the Irish lords, is a genus of ray-finned fishes belonging to the family Agonidae, the poachers and sea ravens. These fishes are found in northern Pacific, northern Atlantic and the Arctic Oceans.
Pleurogrammus is a genus of ray-finned fishes belonging to the family Hexagrammidae, the greenlings, known as Atka mackerels. These fishes are found in the northwestern Pacific Ocean.
Cottoidei is a suborder of ray-finned fishes which, according to the 5th edition of Fishes of the World, is placed within the order Scorpaeniformes, alongside the scorpionfishes, flatheads, eelpouts, sticklebacks and related fishes.
Blepsias bilobus, the crested sculpin, is a species of sculpin belonging to the subfamily Hemitripterinae of the family Agonidae. This species is found in the North Pacific Ocean.
Opisthocentrinae is a subfamily of marine ray-finned fishes, classified within the family Stichaeidae, the pricklebacks or shannies. These fishes are found in the North Pacific Ocean.
Gymnelinae is a subfamily of marine ray-finned fish belonging to the family Zoarcidae, the eelpouts. Most species are found in the North Pacific Ocean but one genus is cosmopolitan, and another is endemic to the Southern Ocean.
Jordaniidae is a small family of marine ray-finned fishes belonging to the order Scorpaeniformes. These fishes are found in the eastern North Pacific Ocean.
Anoplagoninae is a subfamily of marine ray-finned fishes belonging to the family Agonidae, part of the sculpin superfamily Cottoidea. These fishes are found in the North Pacific Ocean.
Brachyopsinae is a subfamily of marine ray-finned fishes belonging to the family Agonidae, part of the sculpin superfamily Cottoidea. These fishes are found in the North Pacific Ocean.
Agoninae is a subfamily of marine ray-finned fishes belonging to the family Agonidae, part of the sculpin superfamily Cottoidea. These fishes are found in the Pacific and Atlantic Oceans.
Bathyagoninae is a subfamily of marine ray-finned fishes belonging to the family Agonidae, part of the sculpin superfamily Cottoidea. These fishes are found in the Pacific and Atlantic Oceans.
