The polar bear is the largest land predator. It lives among the ice and cold seas of the Arctic and mainly feeds on seals.
The polar bear differs from the brown bear in white fur, longer neck, and adaptation to swimming in cold water. It is important as the main predator of the Arctic, helping to maintain balance in nature.
