Các tia vây lưng cứng (tổng cộng) : 17 - 19; Các vây lưng mềm (tổng cộng) : 16 - 17; Tia cứng vây hậu môn: 1; Tia mềm vây hậu môn: 16 - 17; Động vật có xương sống: 34. Two lateral lines, originating above the upper angle of gill opening, branching below the 4th dorsal-fin spine or slightly behind it, upper line running along the first dorsal-fin base and ending below about the end of the first dorsal fin, lower line abruptly curved backward from bifurcation, running mid laterally to the base of the middle caudal-fin ray. Body color is dark brown with slightly metallic reflections, sometimes slightly paler on belly. Dorsal fin membranes with black markings.
Body shape (shape guide): elongated; Cross section: compressed.
Mesobenthopelagic, down to depths of 400 m or more, often at the surface at night around Okinawa, Japan (Ref. 6181). The largest populations are probably on the slope of seamounts or ridges (Ref. 6181). Feeds on a variety of mesopelagic fish, squid and crustaceans (Ref. 6181).
