Random Fun Facts About Polar Bears!

Did you know that the Polar Bear is my favorite animal? No, that's not the random fun fact, just a little more about me.

Polar bears are fascinating animals. Not only are they the world's largest land predators, but also one of the most enigmatic. Researchers believe that polar bears may be just as intelligent as apes, since they seem to be able to learn and modify behavior to match their environmental challenges.  

Polar bears are actually not white. The hair of a polar bear is transparent, made up of a thick hollow core that reflects light. As the light bounces on the air spaces between hairs, you see white, a reflection of all colors combined. This special feature of their hair has a double purpose: it helps them blend better with their environment and it insulates them from the cold and snow.  


And to follow up on that, they are obsessive about keeping clean. Following mealtime, they will spend 15-20 minutes grooming themselves, making sure there is no dirt or residue left on them that may interfere with the insulating properties of their fur.

They are so well padded with fat and thick fur that they can overheat quickly, even in subzero temperatures. To prevent this, polar bears tend to walk slowly, avoid running and spend lots of hours lying down and resting.

They’re excellent swimmers. In fact, they spend so much time in the water that some scientists prefer to classify them as marine mammals. Because their front paws have webbed toes, polar bears are able to paddle better through the water, generating enough momentum to swim for up to 70 miles at a stretch. The webbed toes, along with rough padded feet, are also essential to prevent slipping on the ice.


Unlike all other bear species, Polar Bears don’t hibernate. Pregnant females will curl up in their dens and become less active, but polar bears in general will keep hunting and eating throughout the whole winter. While land bears hibernate, their body temperature drops to about 32F. When polar bears sleep in winter, their body temperature never goes below 88F.  

 
There is a really big difference in size and weight between males and females. While males can reach up to 1500 pounds and 10 feet in length, females rarely exceed 600 pounds and average 6.5 feet in length.  
 
They have been known to have tantrums. Experts have observed frustrated polar bears throwing chunks of ice, kicking piles of snow or growling in disappointment after losing prey they'd been trying to catch.


Finally, one not so fun fact. But considering that Polar Bears are endangered due to global warming and the actions of man - Humans are the only species that preys on polar bears.

I'll leave you with a few links to check out, I encourage you to donate if you can to help save these majestic creatures.
