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.
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.
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.
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.
Hemitripterus is a genus of marine ray-finned fishes, sculpins, belonging to the subfamily Hemitripterinae which is part of the family Agonidae. These fishes are found in the North Pacific and Northwest Atlantic Oceans.
Blepsias cirrhosus, the silverspotted sculpin, is a species of sculpin belonging to the subfamily Hemitripterinae of the family Agonidae. This species is found the northern Pacific Ocean from the Sea of Japan and Alaska to San Miguel Island off southern California.
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.
