CAN POLAR BEAR HAIRS ABSORB ENVIRONMENTAL ENERGY?

ABSTRACT
A polar bear (Ursus maritimus) has superior ability to survive in harsh Arctic regions, why does the animal have such an excellent thermal protection? The present paper finds that the unique labyrinth cavity structure of the polar bear hair plays an important role. The hair can not only prevent body temperature loss but can also absorb energy from the environment.
