Anal organs 14; male supracaudal gland has 5-8, female infracaudal gland with 2-6 small, round to oblong spots, respectively; may be distinguished from all other Myctophum possessing cycloid scales by its angulate, non-serrate, posterodorsal margin of the operculum (Ref. 39633).

High-oceanic, nyctoepipelagic at the surface and to 950 m and generally found between 475-850 m during the day (Ref. 4479). Neustonic to mesopelagic (Ref. 58302). Oviparous, with planktonic eggs and larvae (Ref. 31442). Lipid content is 3.8 % in fresh body weight and wax ester is 10.6 % in total lipids (Ref. 9193).
