Sperm whales are cosmopolitan animals. They inhabit the blue waters of all of the world’s oceans and are often found in deeper offshore areas around canyons and trenches. They can also be found close to shore around volcanic islands such as the Azores, the Galapagos and the Canary Islands, where steep drop-offs run along the coast.

Longer than wider, 3,800 kilometers separate the western most point from the distant eastern shore, while its greatest breadth does not exceed 700km. Its average depth is 1,429 meters, and its surface covers an area of 2.5 million square kilometers, about 1% of the total of the surface of the world’s oceans.
