Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 28.0 cm SL male/unsexed; (Ref. 4172)
A mesopelagic (Ref. 6808) at 300-600 m at night, 625-800 during day (Ref. 58302) and uncommon species. Swims in a vertical position, probably migrates over 200-300 m vertical distance each day-night cycle. Feeds on copepods (Ref. 6741).
