Korte beschrijving
Determinatiesleutels | Morfologie | Morfometrie
Dorsale stekels (totaal) : 0; Dorsale zachte stralen (totaal) : 12 - 14; Anale stekels: 0; Anale zachte stralen: 26 - 29; Wervels: 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.
