背棘 (总数) : 6 - 7; 背的软条 (总数) : 30 - 34; 臀棘: 0; 臀鳍软条: 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).
偏爱深的水域但是雌性与雄性可能被发现于表面之上偶然地。 分布的深度在一月与二月是 150-250 公尺; 三月与四月时的 100-120 公尺。 主要吃片脚类动物 Macrohectopus branickii 。 产卵在七月到十月。 身体的脂肪含量是大约 25% 。 死的鱼不会下沉但是向上漂流到表面而且冻结成冰。 在春天，他们向岸地是外貌藉由波浪。 (参考文献 26334)
