Occur on continental shelf, along its edge and upper slope down to 400 m (600 m in Australia), usually over sandy and muddy bottoms from 100 to 250 m (over 300 m in Australia). Depth range from 333-620 m in the eastern Ionian Sea (Ref. 56504). Migrate into midwater at night. Form schools; occasionally found inshore in upwelling of deep water when it appears at surface. Feed on crustaceans, small squid and fish (Ref. 6768). Eggs and larvae are pelagic (Ref. 6768).
