Short description

Dorsal spines (total): 0; Dorsal soft rays (total): 83-108; Anal spines: 0; Anal soft rays: 62 - 79; Vertebrae: 60 - 64. Dorsal origin behind posterior edge of upper eye. Caudal slightly forked to truncate. Pectorals small.

Often caught pelagically (Ref. 4705). Adults prefer bottom temperatures of -0.5°C to 6.0°C (Ref. 5951). Epibenthic (Ref. 58426). Feed on crustaceans, fishes (Ref. 4705, 6885), eelpouts, capelin, redfishes, deep sea prawns and other bottom invertebrates (Ref. 35388). Batch spawner (Ref. 51846). Utilized dried or salted and frozen; can be steamed and fried (Ref. 9988). Size of the Greenland halibut collected from 400-599 m deep in eastern Bering Sea, ranged from 9 to 99 cm FL with a mean of 56 cm (Ref. 55110).
