From Wikipedia, the free encyclopedia
Clinocottus is a genus of marine ray-finned fishes belonging to the family Cottidae, the typical sculpins. They are nearshore benthic fishes native to the northeastern Pacific Ocean. They are mentioned as sharpnose sculpins.[2]

Taxonomy
Clinocottus was first proposed as a monospecific genus in 1861 by the American zoologist Theodore Gill with Oligocottus analis, which had been described in 1858 by Charles Frédéric Girard from Monterey, California, as its only species.[1][3] Molecular data indicate that this genus is polyphyletic or paraphyletic, it does not constitute a natural assemblage within Cottidae.[4] Workers have found that the lavender sculpin (Leiocottus hirundo) is the sister taxon to C. analis, a species which is not closely related to C. acuticeps. In turn, C. acuticeps is determined to be basal to Artedius,[5] or to the clade referred to as Oligocottinae.[6] The 5th edition of Fishes of the World classifies the genus Clinocottus within the subfamily Cottinae of the family Cottidae,[7] however, other authors classify the genus within the subfamily Oligocottinae of the family Psychrolutidae.[1]
Etymology
Species
There are currently five recognized species in this genus:[9]
- Clinocottus acuticeps (C. H. Gilbert, 1896) (Sharpnose sculpin)
- Clinocottus analis (Girard, 1858) (Woolly sculpin)
- Clinocottus embryum (D. S. Jordan & Starks, 1895) (Calico sculpin)
- Clinocottus globiceps (Girard, 1858) (Mosshead sculpin)
- Clinocottus recalvus (Greeley, 1899) (Bald sculpin)
Characteristics
Clinocottus sculpins are characterised by having the anus in a forward position between the anal fin and the pelvic fins, they have a heavy and blunt penis and in both sexes the anal fin is unmodified. C. analis and C. acuticeps have pointed heads, which is regarded as a basal feature and the remaining 3 species have sizeable, rounded heads. This is suggestive of the paraphyly of the group.[6] These are small sculpins, the largest species is the mosshead sculpin with a maximum published total length of 19 cm (7.5 in) and the smallest is the calico sculpin with a maximum published total length of 7 cm (2.8 in).[9]
