Polar bears are supremely adapted to their environment—they have a number of traits that help them cope with snow, ice and below-freezing temperatures. They are more likely to overheat than to become hypothermic, because of the following characteristics: Their white fur gets camouflaged against the white background of snow protecting it from predators and also helps them catch their prey. Two thick layers of fur act as an insulator protecting them from the surrounding harsh climate. Large Anti-Slip Paws (long curved sharp claws) help a polar bear to walk in the snow. A polar bear has layer of fat under its skin which helps it stay warm. This layer of fat can be 4 inches (10 cm) think. The polar bear’s small ears and tail offer less surface area than large ears or tails, and help maintain body warmth.
