生態學
海洋 居於水底的; 深度上下限 70 - 550 m. 極; 60°S - 78°S
Southern Ocean: South Orkney and South Shetland Islands, tip of Antarctic Peninsula north of 65°S and the Antarctic continental shelf.

Length at first maturity / 大小 / 重量 / 年齡
成熟度: Lm 10.0 range ? - ? cm
Max length : 15.5 cm TL 雄魚/尚未辨別雌雄; (Ref. 124149); 15.3 cm TL (female); 最大體重: 17.00 g (Ref. 124149); 最大體重: 17.00 g
Adults spawn apparently during autumn and early winter. Hatching probably occurs in spring and size at hatching at about 12 mm TL. Main food items are polychaetes and benthic crustacean (Ref. 5192). Larval pelagic phase is short (Ref. 41551).
顯然地在秋天與初冬的時候產卵。 可能孵化出現於春天中而且於大約 12 mm TL 孵出的大小。 主要部份食物組成是多毛類與底棲的甲殼動物。
