Why do polar bears have black skin?

Quick Answer
Black skin absorbs heat from sunlight, while their seemingly white fur is actually made of transparent hairs that scatter light.
The Full Story
Under the thick coat, polar bear skin is black, which helps absorb warmth from the Sun. Their fur hairs are not white but transparent, and they scatter visible light, making the bear appear white against snow for camouflage. A layer of blubber up to about 11 cm thick provides further insulation. They are so well insulated that overheating is a bigger problem than cold when they run.
