Inhabits inshore and near-shore areas, over sand or mud bottoms. Usually found alone or in small, loose aggregates. Adults are pelagic, but near continental margins; young are commonly found on coastal and offshore banks (Ref. 7251). Feeds on fish and shrimps (Ref. 28587). Minimum depth from Ref. 26912. Its flesh is very delicate; nevertheless, in certain region like the Pacific and the Indian Ocean, it is toxic (particularly the skin and the viscera) (Ref. 5377). Poisonous, should not be eaten (Ref. 36731).
