検索表 | 形態学 | 形態計測学
背面の脊椎 (合計) : 0; 背鰭 (合計) : 12 - 14; 肛門の骨: 0; 臀鰭: 26 - 29; 脊つい: 43 - 46. Distinct from closely related species in having a much greater distance between ventral and anal fins, a correspondingly larger number of photophores in the ventral and lateral series.
Mesopelagic, primarily at about 125-300 m depth at night and 520-700 m during the day (Ref. 35800). Oviparous, with planktonic eggs and larvae (Ref. 35800). Also Ref. 58302.
