Environment: milieu / climate zone / depth range / distribution range
Marine; pelagic-oceanic; non-migratory; depth range 100 - 690 m (Ref. 4479), usually 510 - 550 m (Ref. 96467). Deep-water; 46°N - 27°S, 123°E - 14°E

Length at first maturity / Size / Weight / Age
Maturity: Lm ?, range 8 - ? cm
Max length : 9.0 cm SL male/unsexed; (Ref. 4479)
High-oceanic, found between 490-690 m during the day and from 100-200 m at night. Specimens larger than 30 mm are non-migratory (Ref. 4479). Mesopelagic (Ref. 58302). Sexual maturity at a length of 7,5 cm (Ref. 47377). In the Atlantic, gravid females were taken in February and April, suggesting a late summer spawning period (Ref. 96467).
