Description

The darter sculpin is a small sculpin (Cottidae) from the eastern North Pacific, from Alaska to California. The species reaches about 15 cm and, unlike many stocky sculpins, has a strikingly slender, elongate body. It lives demersally on soft sand and mud bottoms and is regularly taken as bycatch in shrimp trawls. The diet consists of small bottom invertebrates. Owing to its small size and inconspicuous habits the species has no direct fishery value.
