The fin whale is the second largest mammal in the world, behind the blue whale.
Although it is still difficult to assess its population precisely, it is estimated that a thousand individuals live in the protected area of the Pelagos Sanctuary, whose purpose is to protect marine mammals in the western Mediterranean, between France and Italy.
The fin whale feeds mainly on krill, small shrimp that it traps in its baleen plates in large quantities. It is capable of diving to depths of over 1,000 metres.
