Taggstrålar i ryggfenan (totalt) : 0; Mjukstrålar i ryggfenan (totalt) : 13 - 15; Taggstrålar i analfenan: 0; Mjukstrålar i analfenan: 18 - 20.
Oceanic, precise depth range dependent upon developmental stage, latitude, season (Ref. 4769). Generally horizontally oriented (Ref. 4769). Feeds on small zooplankton, mostly copepods (Ref. 5162). Sexually dimorphic with large females and small males (Ref. 9503). Sex ratio vary with size groups but is about 1:1 around spawning. Length-frequency histograms are bimodal; has a two-year life cycle (Ref. 82363).
