簡単な記述
検索表 | 形態学 | 形態計測学
背面の脊椎 (合計) : 6 - 7; 背鰭 (合計) : 30 - 34; 肛門の骨: 0; 臀鰭: 30 - 36. No swim bladder (Ref. 128162),
Adults prefer deep waters but females and occasionally males may be found on the surface. Depth of distribution in January and February is 150-250 m; 100-120 m in March and April. Adults feed mainly on the amphipod Macrohectopus branickii. Mature individuals spawn in July to October. Fat content of the body is about 25%. The dead fish does not sink but float up to the surface and freeze into ice. In spring, they are cast ashore by the waves (Ref. 26334).
