The polar bear is the world’s largest land predator. They spend most of their lives on the sea ice of the Arctic Ocean. They are adapted to survive in one of the harshest environments on our planet. It is the largest species of bear as well. It is believed that this species evolved from a common brown bear ancestor approximately 200,000 years ago. These bears may appear white in color but their fur is transparent with a hollow core. It reflects light and this is the reason for its white appearance. Adults are incredible swimmers and can swim for several hours to get one piece of ice to another. Polar bears have black skin underneath the white fur.
