Marukawichthys is a small genus of marine ray-finned fishes belonging to the family Rhamphocottidae, the grunt sculpins and deepwater bullhead sculpins. These fishies are found in the northwestern Pacific Ocean near Japan.
There are currently two recognized species in this genus: [2]
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 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.
The Abyssocottinae are a subfamily of ray-finned fishes in the family Cottidae, the sculpins. They are known commonly as the deep-water sculpins. The entire family is endemic to Lake Baikal in Siberia.
The grunt sculpin or grunt-fish is a small fish mainly found in the eastern Pacific Ocean. The grunt sculpin generally remains close to shore and is often found in empty giant barnacle shells. The common name comes from reports that the fish vibrate or "grunt" when held. Its defining feature is its tendency to “hop” along the ocean floor on its orange fins. The short, stout body of the grunt sculpin has a long, small mouth which is adapted for eating smaller prey.
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 mote sculpin, also known as the barehead scorpionfish, is a ray-finned fish, the only member of the monotypic genus Normanichthys, family Normanichthyidae and suborder Normanichthyiodei. Common names for the species in Spanish include camotillo and bacaladillo.
Scaled sculpins are a group of small benthic fishes living in cold waters. They are mainly found in the North Pacific, with some species in the North Atlantic. They are characterized by a large, laterally compressed head and small spines. The lateral line is present and the dorsal fin base are dotted with scutes (plates).
Myoxocephalus is a genus of fish in the sculpin family Cottidae. Most species live in marine waters, but there are also three freshwater species, including two that occupy northern lakes. The name is derived from Greek myos (muscle) and kephale (head).
Psychrolutes is a genus of fish of the family Psychrolutidae. 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.
Clinocottus is a genus of sculpins, nearshore benthic fishes native to the northeastern Pacific Ocean. They are mentioned as sharpnose sculpins.
Artedius is a genus of sculpins native to the Pacific Ocean. Identified by Charles Frédéric Girard in 1856, it was named after Peter Artedi, a fellow naturalist.
Gymnocanthus is a genus of sculpins, fishes in the family Cottidae.
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.
Triglops is a genus of sculpins.
Batrachocottus is a genus of fish endemic to Lake Baikal in Russia. This genus of sculpins (Cottoidea) is variously considered to belong either to the family Cottocomephoridae, Cottidae or Abyssocottidae.
Ereunias is a monospecific 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.
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.
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.
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.
