The hammerhead shark is an easily recognisable fish species with large flat protrusions on its head & with its eyes on the sides. The shape of its head improves close-quarters manoeuvrability. It can measure up to 5 m in length & weigh up to 150 kg. The hammerhead shark is to be found in all tropical oceans & shallow coastal waters. It mainly eats squid, octopuses & crustaceans. Although the young often form groups, the adults are rather solitary.
