The head is small; eyes large, diameter greater than snout length. Color is yellow-fawn, with irregular oblique brown blotches on the sides. The operculum is silver-black; anus and gill cavity black; belly stippled black; caudal fin base and inner ventral fin rays black.
Found on the continental shelf and upper slope over mud and clay bottom. Catch data indicate a schooling habit. Feeds mainly on bottom-living invertebrates. Also known to feed on pelagic crustaceans like euphausiids, decapods and mysids (Ref. 27637). A hermaphroditic species. Marketed fresh and sometimes made into fishmeal (Ref. 6688). Young are pelagic, living near the surface, the adults are demersal, living between 50 and 1000 m depth (Ref. 47377).
