Scaled sculpin
The scaled sculpins, Icelus, are a genus of marine ray-finned fishes belonging to the family Psychrolutidae, the marine sculpins. Most of the fishes in this genus are found in the northern Pacific Ocean but they also occur in the North Atlantic Ocean.
Taxonomy
The scaled sculpin genus, Icelus was first proposed as a monospecific genus in 1845 by the Danish zoologist Henrik Nikolai Krøyer when he described Icelus hamatus as a new species from Belsund in Spitsbergen. L. hamatus has since been determined to be synonym of Cottus bicornis, which had been described by Johan Reinhardt in 1840 from East Greenland. The 5th edition of Fishes of the World classifies the genus Artediellus within the subfamily Cottinae of the family Cottidae, however, other authors classify the genus within the subfamily Icelinae of the family Psychrolutidae. Previously this genus was classified as the only genus in the family Icelidae which was proposed in 1923 by David Starr Jordan.Etymology
The scaled sculpin genus name, Icelus, is the name of one of the sons of Hypnus, a Greek god of sleep and is a reference to the sluggish movements of many northern sculpin species.Species
