For eight months a year, the ice-covered water of Hudson Bay is the polar bear’s home.  How does the polar bear survive there for so long?  This drawing of ta polar bear is eight feet tall.  Some male polar bears can be ten feet tall when they are standing on their back legs.  Division 10 learned that the polar bears have bodies that are suited for living on the ice.  Their unique features, or adaptations, help keep them warm.  Polar bears have two layers of fur . . . an outer layer that sheds snow, ice and water and a layer of dense fur that keeps heat from escaping.  A polar bear also has black skin.  The skin helps to attract heat.  Under the skin is a thick layer of fat called blubber.
