Polar bears are the second largest species of bear alive today, smaller than only the brown bear. Their size helps them conserve heat; the larger the bear, the more slowly they loose heat. Their fur is a creamy color, not pure white, and they have black skin. Polar bears have a dense underfur and thick layer of fatty blubber to aid in insulation.
