Dorsale stekels (totaal) : 0; Dorsale zachte stralen (totaal) : 7 - 9; Anale stekels: 0; Anale zachte stralen: 18 - 21. Medial face of pectorals with dense black pigment (Ref. 6601).
Body shape (shape guide): fusiform / normal.
Oceanic and mesopelagic (Ref. 6601, 58302). Most adults are taken in hauls to depths exceeding 500 m, none in hauls to depths less than 250 m. Larvae are taken year-round throughout its range, chiefly in hauls to depths less than 200 and apparently not in hauls restricted to the upper 100 m (Ref. 10755). Adults are presumed to prey on other midwater fishes. Synchronous hermaphrodites (Ref. 6691).
