The polar bear is a large, creamy white bear with a long body, long neck, narrow head and very small ears. Its foot pads are covered with fur, its claws and tongue are black, and its eyes are brown. Males are larger than females. In Canada, the polar bear occupies ice-covered areas from Labrador to the Alaskan border. Occasionally individuals are found in insular Newfoundland, usually on spring ice, but later move north again. The polar bear has inspired both awe and respect and in recent years and has become a symbol of the effects of global warming on northern species. Polar Bear
