Have you ever wondered how polar bears survive in the icy Arctic wilderness ? Well, to begin with, their white fur camouflages them when they are out on the ice and in the snow. This makes it easier for them to sneak up on animals they hunt. Their hair filaments are actually transparent, which helps to trap solar energy and keeps the animal warm.
Another adaptation is fat. To protect them from the cold, polar bears have a fat layer which is up to 10 cm thick. The fat also helps the bear to stay afloat in water.
Polar bears have special adaptations to help them swim. Their fore paws are partially webbed to assist in swimming. the massive size of their forelegs helps as well. Moreover, their eyesight is especially adapted for underwater, and their body is streamlined for swimming.
The bear's feet are like snow shoes. The hair on the soles of its feet help the bear walk on the slippery ice and snow. their sense of smell is reported to be amazing! In fact, they can smell a seal 32 km away!
