Short description Bestämningsnycklar | Morfologi | Morfometri

Taggstrålar i ryggfenan (totalt) : 0; Mjukstrålar i ryggfenan (totalt) : 7 - 9; Taggstrålar i analfenan: 0; Mjukstrålar i analfenan: 18 - 21. Medial face of pectorals with dense black pigment (Ref. 6601).

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).
