Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 6.0 cm SL male/unsexed; (Ref. 3988)
An oceanic and mesopelagic species, adults and juveniles usually found at 200-500 m by day and the majority of them migrate into upper 100-200 m at night. Feeds mainly on small crustaceans. Dioecious with peak spawning during summer. Adult photophore complement attained at about 25-27 mm SL (Ref. 4778).
