Gymnocanthus

Gymnocanthus is a genus of marine ray-finned fishes belonging to the family Cottidae, the typical sculpins. These fishes are found in the northern Pacific, Arctic and northern Atlantic Oceans.

==Taxonomy== Gymnocanthus was first proposed as a monospecific genus in 1839 by the English zoologist William Swainson with Cottus ventralis, which had been described in 1829 by the French zoologist Georges Cuvier from Kamchatka, as its only species. Cottus ventralis was later shown to be a synonym of Cottus pistilliger, a species which Peter Simon Pallas had described in 1814 from Alaska.The 5th edition of Fishes of the World classifies this genus within the subfamily Cottinae of the family Cottidae, however, other authors classify the genus within the subfamily Icelinae of the family Psychrolutidae.
