White on White in the unreality of silence. Then a dark muzzle and here is a polar bear (or white bear o).
But in reality, the bear white is not white is black. You can see from the only places not covered by fur: the nose, lips and paw pads. The hairs that cover it, clear and cables, allowing the sun's ultraviolet rays to reach and warm the skin black. So the bear does not suffer from the cold. Indeed, his most serious problem is overheating. Often, after a long walk, has to stop and lie down on the pack to cool the stomach: the thick fur because it adds a layer of fat often up to 10 cm, which helps him stay warm and to float when dives into the icy sea.
The polar bear is an experienced swimmer. Its huge paws and fur waterproof allow him to swim, and hunt underwater for long.

are usually two and weigh only 600 grams, about 750 times less than their mother. The first out of the den is to April, and qu el moment the little family stays together for almost three years.
