The fourspine sculpin (Cottus kazika) is a species of freshwater ray-finned fish belonging to the family Cottidae, the typical sculpins. It is endemic to Japan. It reaches a maximum length of 30.0 cm (11.8 in).[2]
The fourspine sculpin was first formally described in 1904 by the American ichthyologists David Starr Jordan and Edwin Chapin Starks with its type locality given as Niigata in Japan.[3] This species is placed in the monospecific genus Rheopresbe by some authorities, as molecular analyses indicated that this species was a sister taxon to Trachidermus fasciatus, another catadromous Japanese sculpin.[4] The specific name kazika is a Japanese word for river sculpins.[5]
