Adaptations

A polar bear looks white but it is really black because some sunlight bounces off the transparent, hollow tube (hair) and makes it look white.This adaptation is is important because it helps them blend in with the snow. A polar bears paw is like a 25 pound sledge hammer that a polar bear can swing with a deadly force . || [[image:http://t3.gstatic.com/images?q=tbn:ANd9GcT0hkA3BeKQVEB8ERvMTvLcUSF80G8kE9KFeShkiVij10lnSgd0eE6nFTmd width="257" height="192" caption="In this picture you can see that a polar bear's head is bigger than a normal bear's heads"]] ||

Dangers

 * drop in body conditions
 * lower cub survive rates
 * increase in drowning
 * increase in cannibalism
 * loss in denning areas
 * declining populations size

There are about 20,000 to 25,000 polar bears world wide. Scientists believe in 2050 the number of polar bears will drop by a lot because of global warming and oil explorations. || ||

Habitat

 * Polar bears live in conditions that are around -45 degrees to -50 degrees! Over 40% of all polar bears live in Northern Canada. In the summer the ice in the southern part of the Arctic Ocean melts so most polar bears travel north to stay on the ice. Some polar bears travel head south to spend the summer on land. || [[image:http://t3.gstatic.com/images?q=tbn:ANd9GcS75z3M01A16Dp_djIGCVmfhwSFgmYq-n0q0bcVY_8VTn77dtcLHOuiITg width="250" height="186"]] ||
