Short description

Dorsal spines (total): 0; Anal spines: 0. Head relatively broad, interorbital space 18-25% of head length. Generally dark shading to paler ventrally. Peritoneum dark.

Non-schooling (Ref. 28073). Lives close to the coast and is rarely found offshore, in deeper water (Ref. 1371). Benthic, shallows and deepwater to 400 m (Ref. 58426). Feeds on fishes (capelin, polar cod, smaller Greenland cod and Greenland halibut (Ref. 5951)), shrimps, crabs, euphausiids, squids, polychaetes, and echinoderms. There is probably competition between this species and Gadus morhua (Ref. 1371). Over 12 nucleotide substitutions in the 307 base pair region of the mitochondrial cytochrome b gene differentiate this species from Gadus morhua (Ref. 40214).
