Let's take a plunge into the world of these arctic marine mammals. Here are ten super cool facts about polar bears.
1) Although they look white, polar bear's fur is actually made of clear hollow tubes. Their skin underneath is black, but they don't look black because their fur reflects all the colors from the light, much like snow.
2) Bears clean themselves by rolling in the snow. They also cool off by rolling in the snow.
3) A polar bear can smell it's prey from more than 1 kilometer away.
4) Polar bears have no natural enemies.
5) Polar bears can't hunt seals in open water, so they use the ice as a hunting platform and wait for seals to pop their head through the ice or show themselves around the edge of the ice.
6) Polar bears can fast for up to 8 months - how long a female bear spends denning, giving birth, nursing the cubs and hunting for them too.
7) Polar bears have a thick layer of blubber beneath their fur to serve as insulation and buoyancy.
8) Polar bears have been known to swim more than 60 miles without rest. Unfortunately, due to global warming, that distance has been increasing more and more. More and more polar bears starve to death because of this and the fact they have to hunt seal later in the year.
9) All living polar bears descended from the same female brown bear that lived in Ireland about 50,000 years ago.
10) Polar bears have massive, sticky, furry feet. The paws of a polar bear measure up to 30 centimeters across. The bottom of each paw is covered by small, soft bumps known as papillae - these grip the ice and keep the bear from slipping.
