Polar Bears are the largest Bear species in the world. It lives in the far north on the ice sheets. It has been seen on land near human settlements. It mostly eats fish and seals. It is a endangered species because of the loss of habitat. It is believed that the polar bear is going to evolve into a aquatic species of bear.
