Answer

Answer:

blubber

Brief Explanation:

Blubber is a thick layer of fat that insulates polar bears, helping them maintain thermal homeostasis in cold - weather. Fur also helps but blubber is more crucial for heat retention. Finding shade underground is not typical behavior and white skin is for camouflage not heat - retention.
