Scalloped hammerhead  (Sphyrna lewini)

The scalloped hammerhead is found in the warm temperate and tropical waters of the Atlantic, Indian and Pacific Oceans (1). It may also occur in the western Mediterranean Sea (2) (4).

Occurring mainly over continental and insular shelves and the deeper water around them, the scalloped hammerhead also regularly enters enclosed bays and estuaries. It swims at depths of between 0 and 275 metres, and is migratory in some areas, moving poleward in summer (1).
