The polar bear is the world's largest carnivore found on land. It is native to the Arctic Ocean and the surrounding area. The adult male weighs 880 to 1,500 lbs and the female weighs about half of that. Polar bears are closely related to grizzly bears. Although they look quite different, they are descendants from a common ancestor. Their warm fur and a thick layer of blubber protect them from the cold. They can use their huge paws as snowshoes when they walk and as paddles when they swim. We are constantly on the look out for Polar Bear tracks and other signs as we travel.
