Description

The purplegray sculpin is a stocky cold-water sculpin of the family Cottidae reaching about 29 cm. Characteristic are the large, broad head with spines on the gill covers and the broad, fan-shaped pectoral fins with which the fish presses against the bottom; the body has a purple-grey tint with a marbled pattern. The species is adapted to cold water and lives on sand, gravel and stone bottoms of the northern Pacific, including the Bering Sea and the Sea of Okhotsk, from moderate to deep water. As an ambush predator it seizes small crustaceans, worms and molluscs from the bottom. The male guards the clutch laid on the bottom. Locally it comes up as bycatch, but it has little commercial importance.
