  • Webbed toes help the polar bear swim, since they spend most of their time in the water. The smallest foot pad is the front track and the larger is the hind track.
  • There fur is so thick that you would never know they polar bear has black skin. They also have very thick (4 inches) layer of fat. Why do you think they need all that fur and fat?
  • These rules help keep the polar bear population where its at today.
  • The snow den is where the mother polar bear will give birth to her babies and where they spend the winters. Mother polar bears usually give birth to one to three cubs at a time. The babies are much smaller than human babies when born. Can grow to full size within a year if they have lots of food.  
  • When the weather outside gets cold the ocean water will freeze and the polar bears will head out onto the ice to hunt. *will travel hundreds of miles from shore. When the weather warms up and the ice begins to melt is when the polar bears begin to move back to shore.
  • *Fierce predators who eat mostly seals,
  • Polar bears communicate through body language and sounds. Different noises mean different things. A deep growl gives warning to other bears, usually used to defend food. When asking for food from another bear the polar bear will approach slowly, circle the food then offer a nose to nose greeting. When a polar bear wants to play he wags his head side to side, but when an adult bear wants to play he will stand on his hind legs, chin lowered and front paws hanging at his side. When a polar bear is made he will use loud growls and a chuffing sound, which is also what a mother bear usues with her cubs but at lower level.
