The polar bear is one of the largest predators on Earth. These are residents of the harsh and snowy expanses of the Arctic belt, their southern boundary is the tundra zone. Description of a polar bear A polar bear has a heavy, massive body and large, powerful paws.Its weight is from 300 to 800 kg, and the length can reach up to three meters. The color of the fur coat can be from white to yellowish. Summer fur can turn yellow due to the constant exposure to sunlight. Wool stores subcutaneous fat and protects well from cold, so animals do not freeze either on land or under water. The tail of a polar bear is very short, has a length of 7 to 13 cm and is practically invisible from the dense fur. Interestingly, the skin of the bear under the coat is black, like the nose. Their feet have an unusual oblong form, which allows them not to fall under the snow and overcome distances of 30 kilometers.
