Issue
Research shows that this species is restricted to northwestern Pacific ; Austral-Indonesian records are considered to represent two or three undescribed species (see Ref. 87957); distribution will be resolved (linked to correct species) when publications are received.

Maturity: Lm ?, range 34 - ? cm
Max length : 55.0 cm TL macho/indeterminado; (Ref. 122636); peso máx. publicado: 775.00 g (Ref. 122636)
Espinhos dorsais (total): 2; Raios dorsais (total): 0; Espinhos anais 0; Raios anais : 0. Dark grey (Ref. 6577) or brown dorsally, black ventrally, with a distinct black streak above and behind pelvic fins; fins lighter; belly luminous (Ref. 26346). Small and slender with a moderately elongate caudal peduncle and with flank denticles mostly arranged in regular rows. The base of the pelvic flank marking is under the second dorsal-fin spine, the anterior branch is usually longer than the posterior branch, and the caudal marking is considerably longer than the precaudal marking (Ref. 6871).
Found on the outer continental and insular shelves and upper slopes (Ref. 247). Its luminescent belly may attract prey (Ref. 26346), which consists mainly of squid (reported to bite squid bigger than itself), small bony fishes, and shrimps (Ref. 247). Often caught in large schools which may suggest that the luminescence may also be used to keep the group together in the dark deep ocean (Ref. 26346). Ovoviviparous (Ref. 205), size at birth about 15 cm (Ref. 6871).
