Descrição breve
Chaves de identificação | Morfologia | Morfometria
Espinhos dorsais (total) : 0; Raios dorsais moles (total) : 9 - 12; Espinhos anais: 0; Raios anais moles: 14 - 16. Brownish above, sides silvery, iridescent, with black peritoneum showing through (Ref. 7344).
Body shape (shape guide): elongated.
Meso- and bathypelagic at 700-1830 m (Ref. 58302). Probably swift swimmers, which can avoid nets, captured singly or in small groups (Ref. 6692). Carnivorous, feed on squids and pelagic fishes (Ref. 6692). Oviparous and are synchronous hermaphrodites (Ref. 84733).
