Comments: High-oceanic, mesopelagic species, found at 650-1,000 m during daytime, at 40-278 during the night (maximum abundance at 100 m at night) (Ref. 4479).  Feeds on amphipods, calanoid copepods, conchoecid ostracods, and euphausiid larvae and adults (Ref. 4775).  There are larger specimens reported for this species (11 cm by Gibbs et al. (1972) and 12.8 cm from the southwest Atlantic by Parin et al. (1974)) but these may be misidentifications (Ref. 36121).
