Description

The great hammerhead is the largest hammerhead shark (Sphyrnidae) and occurs circumtropically. The species is recognised by its broad, almost straight hammer-shaped head with the eyes at the tips and the tall, sickle-shaped first dorsal fin. It is a coastal to semi-oceanic shark of the continental shelf and open water. As an apex predator it hunts rays, other sharks, fishes and squid; it uses its head to pin stingrays against the bottom. It is critically endangered and is regarded as potentially dangerous to humans.
