Redlist Status

Characteristic

Operculum rounded posterodorsally, abruptly produced into a tapering projection posteriorly. Origin of dorsal fin behind vertical through base of outermost ray of ventral fin. Origin of anal fin under base of penultimate ray of dorsal fin. Base of adipose fin well in advance of vertical through end of base of anal fin. Pectoral fin long, extending to about second AOa, with upper end of its base about on level of ventral margin of orbit. Ventral fin short, not reaching anus. A very small Dn immediately posterodorsad to nasal apparatus. Op1 well developed, opposite middle of expanded portion of maxilla; Op2 somewhat behind vertical through posterior margin of Op1 and well above level of ventral margin of orbit. PLO midway between lateral line and base of pectoral fin or somewhat lower. PO1 through PO4 gently arched; PO5 abruptly displaced dorsalaterally to a position in front of base of outermost ray of ventral fin. VLO distinctly nearer to lateral line than to base of ventral fin, its distance from latter 2-2.5 times as great as that between it and lateral line. SAO series widely angular; SAO1 slightly behind vertical through center of VO3, on line connecting VLO with SAO2; second SAO about over origin of anal fin; SAO3 over AOa1-AOa2 interspace, in contact with lateral line. AOa1 slightly depressed, space between it and AOa2 usually a little wider than spaces between rest of organs of same series. AOp level and equidistant; AOp1 over or somewhat in advance of end of base of anal fin. Pol slightly behind vertical through center of last AOp and in contact with lateral line. Prc widely separated; Prc2 about its own diameter below level of lateral line. Mature males have a large SUGL and a smaller INGL. The former consists of four luminous scales, each completely surrounded by black pigment. INGL is located between the last AOp and the first Prc. INGL small, poor developed, luminous scale widely separated.

habitats

Benthopelagic and mesopelagic in slope and near continental and island waters. Found in 130-300 m during the day and in 10-200 m at night. Feeds in the evening. Feeds on mainly on copepods and various crustacean larvae.

Distribution

Off southern and eastern Taiwan; Indo-West Pacific; Southeast Atlantic.
