Circumglobal: In arctic and temperate waters; northern hemisphere. Sea of Japan off Honshu north to Shishmaref, Alaska in the Chukchi Sea, throughout the Aleutian Islands, and southeast to northern Baja California, Mexico. North Atlantic: New Jersey, USA to Spitsbergen (Svalbard Islands) and the Barents Sea south to Ireland. Northwest Atlantic: Canada (Ref. 5951).
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).
