There are white spots on the flanks near the pectoral fin, and the fins are brown or black with large clear patches. The maximum published standard length of this species is 20 cm (7.9 in).
Blepsias cirrhosus occurs in the North Pacific Ocean, with a distribution ranging from the Sea of Japan north to the Bering Sea, and south along the western coast of North America as far as San Simeon in central California. It is a demersal fish that lives at depths between 0 and 150 m (0 to 492 ft), found in intertidal zones and more commonly in subtidal areas, typically no deeper than 37 m (121 ft).
