The polar bear is a species of large predatory mammal from the bearish family inhabiting the Arctic. It is a peak predator within its reach. Thick fur and a layer of fat protect it from the cold. Hair forming the bear's coat is translucent; the fur as a whole is usually white or cream-colored, which allows the animal to have good camouflage. The skin is black. The polar bear has a short tail and small ears, which helps him reduce heat loss. The relatively small head and long, tapered body give it a streamlined shape suitable for swimming. It is a mammal that leads almost a sea life, in need of survival only a piece of floating ice and food found in the water, and a place for the birth and rearing of the young. His systematic (Latin) name Ursus maritimus means "sea bear". He adapted to life on land, sea and ice.
