Icelinusis a genus of marine ray-finned fishes belonging to the family Cottidae, the typical sculpins. These fishes are found in the northern and eastern Pacific Ocean.

Taxonomy

Icelinus was first proposed as a monospecific genus in 1885 by the American ichthyologist David Starr Jordan with its only and type species being Artedius quadriseriatus. 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 Oligocottinae of the family Psychrolutidae.

Etymology

Icelinus is a diminutive of Icelus, the genus I. quadriseriatus was thought to belong to.

There are currently 11 recognized species in this genus:

Icelinus borealis C. H. Gilbert, 1896 (Northern sculpin)

Characteristics

Icelinus sculpins are characterised by having the fourth uppermost spine on the preoperculum having a number of points like the antler of a deer. They have a single spine and 2 soft rays in the pelvic fin and there are two rows of ctenoid scales along the dorsal fin bases. These are small fishes, the largest species in the genus is I. filamentosus, which has a maximum published total length of 27 cm, while the smallest is I. piestchi which has a maximum published standard length of 4.2 cm.

Distribution

Icelinus sculpins are found in the northern and eastern Pacific Ocean. They are inshore fishes.
