Learn About Polar Bears


Polar bears are superbly adapted for life in a bitterly cold world of pack ice, tundra, coast and boreal forest. Their small ears and tail reduce heat loss, and they are the only bears that are completely covered in fur, except for the nose and pads of their feet. Their thick coat of guard hairs and underfur cover a layer of blubber up to 10cm thick, providing insulation against freezing winds and icy waters. In fact, polar bears are so good at staying warm that, when active, they can overheat when the temperature is only 0 degrees Celsius.

In the wild, polar bears spend the majority of their time travelling and hunting. They will travel many kilometres in a single day, climbing snow banks and steep ridges of ice, and leaping over cracks in th e ice that are more than 6 metres wide. A single bear may range over 3,000 kilometres in a year, covering a home territory that can be as large as 300,000 square kilometres. Polar bears are also adapted for life in the ocean and are expert long-distance swimmers. Their tapered head, streamlined body, and paddle-like feet, which have webbed toes, allow them to swim for many kilometres without stopping.

Wild polar bears are threatened by climate change because it is melting their Arctic home. Polar bears in captivity need help too because many of them are in poor conditions in zoos.
