Did you know: Polar bears actually have black skin
Camouflage:
Polar bears have white fur to camouflage themselves in the Arctic, but their skin is actually black. The fur is translucent and hollow, and reflects light, making the bear appear white.
Absorb heat:
The black skin absorbs UV light from the sun to keep the bear warm. The fur acts like a fiber optic cable, directing the light to the skin.
Protect from UV radiation:
The dark skin protects the bear from the sun's harmful UV rays.
Other features:
Polar bears also have a thick layer of body fat to keep them warm, and a double-layered coat to insulate them from the cold. Their tongue and the inside of their mouth are also dark in color.
