The entire life cycle of marine mammals is linked to the sea. 

Seals give birth on ice or on land, while whales live their entire lives at sea. Some marine mammals roam over large areas, others are more indigenous. Some whale species migrate from the Arctic to the Antarctic. The polar bear also has a life closely linked to the sea and hunts mainly on the ice.

Polar Bear 

The polar bear (Ursus maritimus) is distributed around the entire Arctic region and is the world's largest land predator. Polar bears live both in Svalbard and in the ice-covered waters around. They hunt mainly out on the sea ice, and are dependent on ice-covered sea to find sufficient food. Climate change and pollution are the main threats to the polar bear.
