The polar bear is a bear native largely within the Artic Circle encompassing the Arctic Ocean, its surrounding seas and surrounding land masses. It is the world's largest land carnivore and also the largest bear, together with the omnivorous Kodiak Bear, which is approximately the same size. A boar (adult male) weighs around 350–680 kg (770–1,500 lb), while a sow (adult female) is about half that size.
Life about Polar Bears
Polar bears find a seal air hole and sneak up on it slowly and sit there until a seal comes up to breathe and then they scoop him right out of the hole. Polar bears have fur that is made up of "hollow guard hairs." Sometimes when polar bears live in zoos that are in a warmer climate, they can have algae growing inside the hollow guard hairs of their fur. This makes them have a greenish tint to their fur. These hollow hairs also keep their hair from matting down when they swim in water
