Environment: milieu / climate zone / depth range / distribution range
Marine; benthopelagic; depth range 10 - 300 m (Ref. 4066). Deep-water; 37°N - 33°S, 33°E - 154°E
Indo-West Pacific: From about 25°S off Mozambique to the Gulf of Oman, east to the Bay of Bengal, Indonesia and western Australia, and north to Japan. Southeast Atlantic: Larvae were present in cruise collections off the eastern coast of South Africa, however, adults have not been reported in this area (Ref. 41388).

Maturity: Lm ?  range ? - ? cm
Max length : 7.0 cm TL male/unsexed; (Ref. 9835)
Benthopelagic and mesopelagic in slope and near continental and island waters (Ref. 9835, 11230). Found in 130-300 m during the day and in 10-200 m at night (Ref. 4066). Feeds in the evening (Ref. 9191). Feeds on mainly on copepods and various crustacean larvae. Lipid content is 4.6 % in fresh body weight (Ref. 8966).
