Interestingly, the polar bear’s coat has no white pigment; in fact, a polar bear’s skin is black and its hairs are hollow.

Detailed explanation-4: -Polar bears live in one of the planet’s coldest environments and depend on a thick coat of insulated fur, which covers a warming layer of fat. Fur even grows on the bottom of their paws, which protects against cold surfaces and provides a good grip on ice.

Detailed explanation-5: -To live in an extremely cold climate, the polar bear has many adaptations, such as: (a) The layer of fat under the skin for insulation. (b) Long curved and sharp claws to walk and run on slippery ice. (c) Thick white fur.
