生态学
海洋 深海区的; 深度上下限 1239 - 2000 m (Ref. 58018). 深水域; 25°S - 60°S
Subtropical to temperate waters in the southern hemisphere, probably limited by the subtropical convergence. Incidentally found in sub-Antarctic waters of the Southern Ocean.
亞熱帶的對溫帶的水域在南半球, 可能侷限於亞熱帶的集中。 附隨地發現於南極海的亞南極水域了。

简单描述
型态特徵 | 形态测量图
背棘 (总数): 0; 背的软条 (总数): 55-63; 臀棘 0; 臀鳍软条: 37 - 42. Pelvic fins with 6 rays (females), absent in males.
腹鳍有 6 鳍条 (雌性),不存在于雄性。
Mesopelagic species (Ref. 75154). Pronounced sexual dimorphism: females are black, with well developed canine teeth, barbel and pelvic fins with six stripes. Males are dark-brown, have no teeth on maxilla and neither barbel nor pelvic fins (Ref. 47377). Apparently, females live below 500 m during the day and perform vertical migration at night to shallower depths; males always in deep water, ca 1,000-2,000 m (Ref. 5169).
明显的性同种二形: 雌性是黑色的, 有发展良好的犬齿，触须与腹鳍有六条斑纹。 雄性是深褐色的, 已经没有牙齿在颚骨与没有一个触须也不腹鳍.(参考文献 47377) 显然地，雌性对深度较浅的地方在 500 公尺之下生活在白天期间而且在晚上执行垂直性回游; 雄性总是在深水中, ca 1,000-2,000 公尺.(参考文献 5169)
