生態學
海洋 深海區的; 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。

簡短描述
檢索表 | 型態特徵 | 形態測量圖
背棘 (總數) : 0; 背的軟條 (總數) : 55 - 63; 臀棘: 0; 臀鰭軟條: 37 - 42. Pelvic fins with 6 rays (females), absent in males.
腹鰭有 6 鰭條 (雌性),不存在於雄性。
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).
明顯的性同種二形: 雌性是黑色的, 有發展良好的犬齒，觸鬚與腹鰭有六條斑紋。 雄性是深褐色的, 已經沒有牙齒在顎骨與沒有一個觸鬚也不腹鰭.(參考文獻 47377) 顯然地，雌性對深度較淺的地方在 500 公尺之下生活在白天期間而且在晚上執行垂直性迴游; 雄性總是在深水中, ca 1,000-2,000 公尺.(參考文獻 5169)
