Distribution Countries | FAO areas | Ecosystems | Occurrences | Point map | Introductions | Faunafri

Indo-West Pacific: Arabian Sea to about 25°S off Mozambique and to the western Pacific region. Occurrence in the northwest Pacific and eastern Indian Oceans need confirmation (Ref. 9835). 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).

Biology     Glossary (e.g. epibenthic)

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).
