IUCN status: endangered
Size: up to 6m
Easily identified by its broad, flat head, this large shark is found in northern Australian waters from Sydney to the Houtman Abrolhos, WA. While few attacks on humans have been recorded, the great hammerhead is considered dangerous. It feeds on fish, other sharks, crustaceans and cephalopods, but is best known for its appetite for rays, which it pins to the sea floor with its head before taking a bite out of the ray’s wing, incapacitating it.
