简单描述
型态特徵 | 形态测量图
背棘 (总数): 0; 背的软条 (总数): 0; 臀鳍软条: 13 - 16; 脊椎骨: 81 - 85. In adults, head depth 21.3-23.2% of lower jaw length; postorbital region 5.0-6.7% SL or 25.5-30% HL (1/3 of HL). Rear edge of gill cover overlaps with the vertical of the middle of the 4th vertebrae. Pectoral fins begin at the vertical of the end of the 4th to beginning of 5th vertebrae. Postadipose distance represents 4.6-5.9% SL (Ref. 31260).
当成鱼时, 头部深度 21.3-23.2% 的下颌长度; 眼眶后的区域 5.0-6.7% SL 或 25.5-30% HL(HL 的 1/3). 鳃盖的后缘与第 4个脊椎骨的中央的垂直者部分重叠。 胸鳍对第 5个脊椎骨的开始从第 4 个的末端的垂直者开始。 Postadipose 距离代表 4.6-5.9% SL 。 (参考文献 31260)
Inhabits the epimesopelagic layer of the southern ocean circumglobally. Only fry and juveniles were observed in subtropical waters; large adults encountered in sub-Antarctic and Antarctic waters. Capable of shedding teeth and reducing gastrointestinal tract prior to spawning. Monocyclic, that is, they die after the first spawning (a reproductive strategy that evolved as a result of the large distance between feeding and spawning areas). Main food is
Notolepis coatsi which are 15-38 cm in length and weighs to 57-90 g (Ref. 31260).
栖息于南方海洋 circumglobally 的 epimesopelagic 层。 只有鱼苗与稚鱼在亚热带水域被观察; 大的成鱼在亚南极与南极圈水域中见到了。 能够脱落齿而且在产卵之前减少肠胃道。 单周期的, ，那是, 他们死在第一次产卵之后.(进化的一个生殖的策略作为一个在觅食与产卵区域之间的长距离的结果) 主要部份食物是
考氏背鳞鱼［Notolepis coatsi］ 那是 15-38 公分长而且对 57-90 g 重量。 (参考文献 31260)
