生态学
海洋 底中水层性; 深度上下限 200 - 800 m (Ref. 5200). 極; 60°S - 78°S, 180°W - 180°E (Ref. 5200)
Southern Ocean: Circum-Antarctic on Antarctic continental shelf. Northernmost records from vicinity of South Orkney Islands and Antarctic Peninsula.

Length at first maturity / 大小 / 重量 / 年龄
Maturity: Lm ?, range 23 - ? cm
Max length : 43.0 cm TL 雄鱼/尚未辨别雌雄; (Ref. 5200); common length : 30.0 cm TL 雄鱼/尚未辨别雌雄; (Ref. 2805)
背棘 (总数): 5 - 8; 背的软条 (总数): 38-42; 臀棘 0; 臀鳍软条: 32 - 36. Supraorbital ridge not crenulated. Middle lateral line restricted to caudal peduncle; lower lateral line originating from in front of anal-fin origin to above sixth anal ray. Maxilla extending to below anterior third of eye. Opercular bones with 2 upper and 3 lower spines. Preopercular-mandibular canal not joined to temporal canal. Pelvic fins extending beyond anal-fin origin. In life, pale grey, whitish ventrally. Differentiated by the dorsoventrally oval shape; the prominent distally rounded rostrum, pseudo-rostrum and pseudo-antirostrum; the clearly defined excisura ostii and pseudo-excisura ostii; the acutely constricted collum; and the well developed colliculli.
Ontogeny: The excisura ostii and the pseudo-excisura ostii become deeper and the crista inferior becomes less distinct with an increase in the fish size.
不细齿状的眶上的脊。 中央侧线局限于尾柄了; 低的侧线在臀鳍前面起源方面起源于在第六个臀鳍鳍条之上。 在眼的前三分之一之下颚骨延伸至。 鳃盖硬骨有两个上面的与 3个下面的棘。 前鳃盖骨-颚骨管不连到了暂生管。 腹鳍延伸超过臀鳍起源。 活着时, 白灰色, 微白色的腹地。 藉由有背腹性椭圆形的形状区别了; 突出的末梢部圆形的喙, 假的-喙与假的-antirostrum; 界线明确的 excisura ostii 与假-excisura ostii; 尖锐地压缩的 collum; 而且发展良好的 colliculli。
个体发生: 变得比较深的 excisura ostii 与假-excisura ostii 与 crista 下方的变得较不明显有一个鱼大小的增加。
Common in shallower waters of the continental shelf, especially on banks less than 250 m deep in areas where local upwelling increase food supply (Ref. 6390). Postlarvae and pelagic juveniles are also found in the upper 100 m (Ref. 5200). Food consists of fishes and krill. Spawn in winter (Ref. 6390). Larval pelagic phase is long (Ref. 28915). Prey to penguins and seals (Ref. 6390). Utilized as a food fish (Ref. 5200).
大陆架的常见于较水浅的水域, 尤其在浅堆上在地方涌升流增加食物供应的区域中少于 250 公尺深。 (参考文献 6390) 食物由鱼与磷虾组成。 冬天时产卵。 (参考文献 6390) 企鹅与海豹的猎物。 (参考文献 6390) 作为食用鱼.(参考文献 5200)
