簡短描述
檢索表 | 型態特徵 | 形態測量圖
背棘 (總數) : 6 - 7; 背的軟條 (總數) : 30 - 34; 臀棘: 0; 臀鰭軟條: 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).
偏愛深的水域但是雌性與雄性可能被發現於表面之上偶然地。 分布的深度在一月與二月是 150-250 公尺; 三月與四月時的 100-120 公尺。 主要吃片腳類動物 Macrohectopus branickii 。 產卵在七月到十月。 身體的脂肪含量是大約 25% 。 死的魚不會下沉但是向上漂流到表面而且凍結成冰。 在春天,他們向岸地是外貌藉由波浪。 (參考文獻 26334)
