Jordaniidae is a small family of marine ray-finned fishes belonging to the order Perciformes. These fishes are found in the eastern North Pacific Ocean.
Jordaniidae was first proposed as a subfamily, Jordaniinae, of the family Cottidae in 1898 by the American ichthyologists David Starr Jordan and Barton Warren Evermann. [1] The 5th edition of Fishes of the World classifies this family within the superfamily Cottoidea, in the suborder Cottoidei of the Scorpaeniformes. [2] Other authorities classify this family within the infraorder Cottales within the order Perciformes, as they suggest that Perciformes is paraphyletic if the Scorpaneiformes are excluded from it. [3] The cabezon (Scorpaenichthys marmoratus) is classified within the Jordaniidae by some authorities [4] but the 5th edition of Fishes of the World classifies this species in the monotypic family Scorpaenichthyidae. [2] This family is regarded as one of the more basal members of the Cottoidea grouping. [5]
Jordaniidae takes its name from its type genus, Jordania, which was named by Edwin Chapin Starks in 1895 and Stark's' name honours David Starr Jordan who was his "teacher in ichthyology". [6]
Jordaniidae contains two monotypic genera: [2] [4]
Jordaniidae sculpins have a single pharyngobranchial on the gill arch, 5 finrays in the pelvic fin a long body with a long based anal fin, 2 separate dorsal fins and reduced gills. [2] These fishes reach a maximum published total length of 15 to 20 cm (5.9 to 7.9 in). [7] [8]
Jordaniidae sculpins are found in the eastern Pacific Ocean from Alaska to California. They are demersal fish found from the intertidal zone to 138 m (453 ft) in rocky areas. [8]
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.
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.
Rhamphocottus is a genus of marine ray-finned fishes belonging to the family Rhamphocottidae. These fishes are known as grunt sculpins. The grunt sculpins are found in the North Pacific Ocean.
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.
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.
Zoarcoidei is a suborder of marine ray-finned fishes belonging to the order Perciformes. The suborder includes the wolffishes, gunnels and eelpouts. The suborder includes about 400 species. These fishes predominantly found in the boreal seas of the northern hemisphere but they have colonised the southern hemisphere.
Aulorhynchidae, the tube-snouts, is a small family of marine ray-finned fishes belonging to the suborder Gasterosteoidei in the order Perciformes. These fishes are found in the northern Pacific Ocean.
Cryptacanthodes is a genus of marine ray-finned fishes belonging to the monogeneric family Cryptacanthodidae, commonly referred to as wrymouths. Three of the four species are found in the Pacific Ocean with one species native to the western Atlantic Ocean where they are benthic fishes, tunneling through soft substrates. It is currently the only known genus in its family.
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.
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.
The longfin sculpin is a species of marine ray-finned fish belonging to the family Jordaniidae, a small family of sculpins. This species is found in the northeastern Pacific Ocean. This species is the only known member of its genus, Jordania.
Megalocottus is a small genus of marine ray-finned fishes belonging to the family Cottidae, the typical sculpins. These fishes are found in the western Pacific Ocean.
The spineless sculpin is a species of marine ray-finned fish belonging to the family Cottidae, the typical sculpins. This species is found in the Pacific Ocean where it is endemic to the waters around the Aleutian Islands, Alaska.
Ereunias is a monotypic genus of marine ray-finned fish belonging to the family Rhamphocottidae, the grunt sculpins. Its only species is Ereunias grallator which is a bathydemersal species found at depths of around 500 m (1,600 ft) in the northwestern Pacific Ocean off Japan. This species attains a maximum published total length of 30 cm (12 in). This species was first formally described in 1901 by the American ichthyologists David Starr Jordan and John Otterbein Snyder from Misaki, Sagami in Japan. Jordan and Snyder proposed the new genus Ereunias for the new species. The genus name is derived from ereunao, meaning "to explore" which may refer how it uses elongated pectoral-fin rays as feelers or “feet” to explore the substrate; suffixed with ias which is used in some Greek names for fishes. The specific name grallator is "stiltwalker" in Latin and is an allusion to the elongated pectoral fin rays. Along with the genus Marukawichthys this taxon was classified in the family Ereunidae but this was synonymised with the Rhamphocottidae in 2014.
Blepsias is a genus of marine ray-finned fishes belonging to the family Agonidae, the poachers and related fishes. These fishes are found in the coastal northern Pacific Ocean from Japan to California.
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.
The butterfly sculpin is a species of fish in the family Agonidae. It is found in the North Pacific Ocean.
Rhamphocottus nagaakii is a species of marine ray-finned fish belonging to the family Rhamphocottidae, the grunt sculpins. This species was first formally described in 2022 with its type locality given as off Minami-Sanriku cho in Miyagi Prefecture of Japan. It is thought to have evolved from a common ancestor to the grunt sculpin but the two species were thought to have been separated by a cooling event during either the Pliocene or Miocene. This species differs from the grunt sculpin genetically and morphologically. The specific name honours Nagaaki Satoh, a professional diving instructor, who was the first to observe the reproductive behaviour of R. nagaakii and passed these observations to the species' describers.
Cottus jaxartensis is a species of freshwater ray-finned fish belonging to the family Cottidae, the typical sculpins. This fish is endemic to the basin of the Syr-Darya in Uzbekistan, Kazakhstan and Kyrgyzstan. This species is classified within the nominate subgenus of the genus Cottus and it is closely related to the European bullhead of which it was considered as subspecies. The specific name, jaxartensis, means "of the Jaxartes", the ancient name of the Syr Darya River.
