Fun Friday Fact

Polar bear fur isn't white. Honest! Polar bear fur is made up of clear hollow tubes that help to insulate the bears and keep them warm. Their skin is black and it is a combination of their fur, skin and a thick layer of blubber or fat under the skin that all work to keep the bears toasty in the cold arctic home.

Now before anyone starts correcting their teachers (and getting ME in trouble) and saying that polar bears aren't white, they -look- white because the clear fur reflects the light from the snow and ice of the area. They look yellowish sometimes from the oils in the foods they eat.
