A polar bear’s black skin absorbs and retains heat from the sun, helping them stay warm in their cold Arctic environment. Their fur, although appearing white, is actually transparent and helps in reflecting sunlight.
The black skin allows them to absorb more UV light to stay warm. The hair of the polar bear acts like a fiber optic cable directing the light to the surface of the skin. The clear hair reflects all wavelengths of light giving them a white appearance that blends with their surroundings.
