Explanation:
Polar bears have white fur so that they can camouflage into their environment. Their coat is so well camouflaged in Arctic environments that it can sometimes pass as a snow drift. Interestingly, the polar bear's coat has no white pigment; in fact, a polar bear's skin is black and its hairs are hollow.

Answer:
A polar bear’s fur is transparent. It’s made up of hair which are hollow and reflect light. It varies depending on the environment and diet of the bear. Captive bears have been observed to turn green in colour due to growth of algae on its fur.
Under all that fur, a polar bear’s skin is actually black. This helps to maximise heat retention.
