One of the most impressive animals is the Scalloped Hammerhead Shark (Sphyrna lewini). Specially the Hammerhead is unique in fauna and works like a radar system. During the shark swims close above sea bottom he detects any magnetic field of prey animals in the sand. The organ with this function is located at the underside and you will see the small dark spots with name Ampullae of Lorenzini.
