Smoothhead Sculpin

Artedius lateralis

The Smoothhead Sculpin is a small marine fish belonging to the family Cottidae. It is characterized by its smooth head, lacking scales, and a rounded caudal fin. It typically grows up to 14 centimeters in length. The species is equipped with 7 to 10 dorsal spines and 15 to 17 dorsal soft rays, while the anal fin contains 12 to 14 soft rays. The lower pectoral rays are notably thickened and exserted, and the pelvic fins are relatively small. This fish is commonly found in the northern Pacific, ranging from the Komandorski Islands in Russia and the Bering Sea coast of Alaska to northern Baja California, Mexico. It inhabits the intertidal zone and can be found at depths up to 13 meters, though it is most frequently encountered in shallower waters. The Smoothhead Sculpin is adapted to life in rocky coastal environments and can often be found under rocks or seaweeds, where it may remain out of water and breathe air. The Smoothhead Sculpin's breeding involves depositing eggs in a mass among rocks in protected locations. Divers encountering this species may find it in tide pools or shallow rocky reefs, where it exhibits bottom-dwelling behavior. The species has not been evaluated for conservation status by the IUCN.
