A coastal-pelagic, semi-oceanic shark, found close inshore and well offshore, over the continental shelves, island terraces, and in passes and lagoons (Ref. 244, 58302). Often bottom and reef associated at 1-80 m (Ref. 58302). Prefers to feed on stingrays and other batoids, groupers and sea catfishes, but also preys on other small bony fishes, crabs, squid, other sharks, rays, and lobsters (Ref. 244, 13562, 1602). A viviparous species, with 13-42 of about 56 to 70 cm young in a litter (Ref. 26938, 1602). Potentially dangerous to people (Ref. 13562) but only few, if any, of the attacks on people can be definitely attributed to it because of the apparent difficulty of distinguishing large hammerhead species involved in attacks (Ref. 244). Caught occasionally by target shark longline, demersal tangle net and tuna gillnet fisheries (Ref.58048). Meat utilized for human consumption (fresh, fresh-frozen, dried-salted, and smoked), liver oil for vitamins, fins for soup, hides for leather, and carcasses for fishmeal (Ref. 244). Its large fins, including the tail, sail-like first dorsal fin, are prized in the Oriental sharkfin trade (Ref. 47737).
