A pelagic (Ref. 26340) schooling species usually found in offshore reefs (Ref. 9710). Juveniles are encountered along shores of sandy beaches, also over muddy bottoms (Ref. 9626). May penetrate into brackish water and ascend rivers. Often approach divers (Ref. 9710). Roving predator which patrol while swimming near the surface or at mid-water, lunging mainly at small fishes. Feed on benthic, rocky dweller fishes (Ref. 43310), shrimps, and other invertebrates (Ref. 3277). Seems to forage mainly at twilight (Ref. 40396).
