Descrição breve
Chaves de identificação | Morfologia | Morfometria
Espinhos dorsais (total) : 0; Raios dorsais moles (total) : 17 - 21; Espinhos anais: 0; Raios anais moles: 18 - 24; Vértebras: 47 - 51. This species possess the following characters: in male, postorbital photophore (PO) 5.8-11.9% upper jaw length (UJL), 1.5-3.1% SL; female PO 2.8-8.1% UJL, 0.8-11.9% SL; IP photophores 3-5 in 3-5 clusters (Ref. 78501).
Body shape (shape guide): elongated.
Meso- and bathypelagic (Ref. 58302). It has been suggested that this species does not undergo substantial diel vertical migration and remains below 500 m (Ref. 78501). Feeds on crustaceans and fishes (Ref. 58426).
