生态学
海洋 居于水底的; 深度上下限 110 - 300 m. 極; 65°S - 79°S
Southern Ocean: Antarctic continental shelf. Probably circum-Antarctic.
南極海: 大陸棚南極圈。 可能 circum-南極圈。
大小 / 重量 / 年龄
成熟度: Lm ? range ? - ? cm
Max length : 45.3 cm TL 雄鱼/尚未辨别雌雄; (Ref. 124149); 49.1 cm TL (female); 最大体重: 404.20 g (Ref. 124149); 最大体重: 404.20 g
Specimens larger than 26 cm TL were breeding. Spawning seems to take place in autumn or early winter. Feeds mainly on benthic and benthopelagic organisms such as fishes (Trematomus spp.), the decapod Crangon antarcticus, mysids, gammarid amphipod and polychaete worms (Ref. 5192). Minimum depth from Ref. 58018.
标本大于 26 公分TL 被繁殖。 产卵似乎秋天时发生或初冬。 主要吃底栖性与大洋底栖性鱼种生物例如鱼 ( Trematomus spp.), 十足目的 Crangon antarcticus ，糠虾, 夜蛾片脚类动物与多毛类的蠕虫。
