Scalloped Hammerhead Shark Sphyrna lewini

The Scalloped Hammerhead Shark has a large range, being native to temperate and tropical coastal waters around the world. Despite its range, it is critically endangered through overfishing for its fins, exacerbated by slow maturity.

Distinguished by the scalloped head shape, the eyes and nostrils are at the ends of the "hammer". The hammerhead, which has electroreceptors on the underside, is used for pinning prey down on the seabed; prey is mainly fish and invertebrates but includes other smaller sharks and rays.

The Scalloped Hammerhead can grow to some 4.3metres (14 feet).
