Taggstrålar i ryggfenan (totalt) : 0; Mjukstrålar i ryggfenan (totalt) : 12 - 14; Taggstrålar i analfenan: 0; Mjukstrålar i analfenan: 18 - 20; Ryggkotor: 31 - 32. Anal organs 10-11; mature males have large 3 to 5 translucent supracaudal gland and smaller infracaudal gland; mature females have small supracaudal gland and much smaller infracaudal patches (Ref. 39633).
Body shape (shape guide): fusiform / normal.
Benthopelagic and mesopelagic in slope and oceanic waters, but usually not high-oceanic. Occurs in the upper 200 m at night (Ref. 4066). Epipelagic in nearshore areas at 0-856 m (Ref. 58302). Occasionally seen during dark nights on slopes that are near very deep water. Attracted by light like moths, becoming disoriented and darting frantically in all directions (Ref. 48635).
