Bear flip flops for bear lovers - The coolest paw prints ever!!
Polar bears fur is see-through / clear!

Although polar bears appear white, their fur is actually transparent. It only appears white, because it reflects sun light. Under their fur, polar bear skin is actually black.
To humans and other animals that can see only in visible light, the bears appear to blend in with their snowy surroundings. But reindeer, which polar bears sometimes prey on, can see in ultra-violet light, which makes polar bears stand out from their snowy environment.

Cool Fact #1

Males can weigh as much as a dozen men
An adult male bears typically weighs between 775 and 1,200 pounds, or the weight of about five to seven men. The largest polar bear ever recorded was a male weighing 2,209 pounds.  By contrast, adult females weigh only half as much as males, or 330 to 650 pounds.

Cool Fact #2

Mother bears don't hibernate
The bears don't hibernate, but mother bears live in dens while they raise their cubs. While mama bears are in their dens (generally between January and March), they don't eat, drink or defecate.

Cool Fact #3

Wolves helping bears in Yellowstone
The wolves have kept the park's population of elks (prey for wolves) in check, which in turn limits how many berry-producing shrubs the elks consume. As a result, the bears have more tasty berries to eat, finds a study published in the Journal of Animal Ecology.
