生態學
海洋 居於水底的; 深度上下限 110 - 300 m. 極; 65°S - 79°S

大小 / 重量 / 年齡
Maturity: Lm ? range ? - ? cm
Max length : 45.3 cm TL 雄魚/尚未辨別雌雄; (Ref. 124149); 49.1 cm TL (female); 最大體重: 404.20 g (Ref. 124149); 最大體重: 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.
標本大於 26 公分TL 被繁殖。 產卵似乎秋天時發生或初冬。 主要吃底棲性與大洋底棲性魚種生物例如魚 ( Trematomus spp.), 十足目的 Crangon antarcticus ，糠蝦, 夜蛾片腳類動物與多毛類的蠕蟲。
