生態学
海 底生の漂泳性; 移住性ではない; 深さの範囲 100 - 1000 m (Ref. 1371), usually 300 - 500 m (Ref. 54573). Temperate; 0°C - 4°C (Ref. 1371); 82°N - 37°N, 95°W - 61°E (Ref. 54573)
North Atlantic: Norfolk Canyon and George Bank north to Labrador, Davis Strait, eastern and western Greenland, Iceland, and from the Irish Atlantic slope north to Faeroe Islands, Norwegian coast, to Spitzbergen, and to the Barents Sea.
Length at first maturity / サイズ / 重さ / 年齢
Maturity: Lm 54.3 range ? - ? cm
Max length : 110 cm TL オス/雌雄の選別がない; (Ref. 35388); 最大記録サイズ: 25 年 (Ref. 1371)
背面の脊椎 (合計): 0; 肛門の骨 0. Snout short, rather strongly pointed; mouth small, inferior. Underside of head almost entirely naked. Pyloric caeca about 19 or 20. Overall color is gray, darker ventrally on trunk; anal fin dark-edged, first dorsal and pectoral fins dusky (Ref. 1371). Front end of dorsal fin spine is serrated (Ref. 35388).
Epibenthic, in deep waters down to 2740 (Ref. 58426). Adults are commonly found in about 300-500 m depth. Temperature preferences appear to range from about 1-4°C, although bottom temperatures below 0°C have been recorded at capture depths. Amphipods predominate in the diet, although polychaetes and various natant crustaceans are also important. Also feed on bivalves, isopods, echinoderms (notably ophiuroids), and ctenophores (Ref. 1371). Batch spawner (Ref. 51846).
