Description Adults, bentho- to mesopelagic, dwell on the continental slope or underwater rises, migrate to midwater at night. Larvae and juveniles, epi- to mesopelagic, are rather common in oceanic ichthyoplankton and are only found in the tropics. Feeds on squid, fish and crustaceans. Reproductive year round in warmer seas (Ref. 9784). Consumed as food (Ref. 4537). [details]

Distribution Probably distributed worldwide in tropical and subtropical seas except in eastern Pacific and northern Indian oceans. Large-sized individuals stray in cold-temperate waters off Iceland, Norway, northern Japan and southern New Zealand; found in Canadian Atlantic 43.3°N to 30.45°N [details]
