Found on the outer continental and insular shelves and upper slopes (Ref. 247). Usually on or near the bottom but sometimes found well above it (Ref. 5578). Apparently in large schools (Ref. 5578). Feeds on pelagic bony fish, squid, octopus and shrimp (Ref. 5578). Ovoviviparous (Ref. 50449). Caught very rarely by demersal longline fisheries operating in deepwater of Indonesia. Utilized for its meat, fins (low value) and liver oil (very high value) (Ref. 58048).
