Espinhos dorsais (total) : 0; Raios dorsais (total) : 10 - 12; Espinhos anais: 0; Raios anais : 22 - 30. Dark dorsum, flanks silver (Ref. 3988). Slender body, longer anal fin and tail set (Ref. 37473).
An oceanic and mesopelagic species, adults and juveniles usually found at 200-500 m by day and the majority of them migrate into upper 100-200 m at night. Feeds mainly on small crustaceans. Dioecious with peak spawning during summer. Adult photophore complement attained at about 25-27 mm SL (Ref. 4778).
