| TT - 13 Interesting Facts about Polar Bears |
Polar bears are the largest land predator in the world.
A polar bear’s fur is not white; it is colorless. A reflection off the bear’s fur shatters light and makes the fur look white.
If you plucked out a polar bear’s fur (which I don’t recommend) you would find that its skin is black. The black skin absorbs the light from the sun and keeps the polar bear warm when temperatures plummet to -50 degrees Fahrenheit
Almost five inches of blubber provides polar bears with an insulating blanket.
If temperatures plummet, polar bears dig a snow cave, curl up into a ball and cover their nose with a paw. Why? Because the bear’s muzzle radiates heat and helps it to keep warm.
A polar bear has small ears and a small tail in proportion to the rest of its body. Being so compact heat cannot be lost through these areas.
Polar bears can communicate with others of their species through body language and vocal sounds.
Adult polar bears love mock battles and fighting. It’s their form of entertainment.
Submissive polar bears always travel down wind of dominant polar bears in order to avoid confrontation.
Polar bears signal aggression by lowering their head, hissing and snorting. If a polar bear is planning to attack, its head will be down and its ears will be laid flat on its head.
Male polar bears, called boars, can weigh 770 to over 1,400 pounds. Female polar bears, called sows, weigh about 330 to 550 pounds. But the biggest polar bear ever known was a male weighing 2,209 pounds and measuring twelve feet long.
Their nostrils actually close up under the water and they can easily swim for many hours at a time.

I love polar bears, but I have never seen one outside of a zoo. Beautiful animals! Happy TT :)
-
I knew most of these! Why? I'm not sure...Aside from the fact that polar bears are beautiful and fascinating.
Happy TT!
-
Clear fur? Black tongue. That is fascinating. I wonder if the fur changes through the warmer months?
-
Very interesting facts. I do think I have some of that blubber though. Have a great TT. :)
-
Once again you are doing a good job of educating me! Fascinating...
-
I like polar bears but I never knew that their tongue was black. I like them because they're so white and furry and though huge, they're cute.
-
I always look forward to your TT. Thanks for doing such a great job.

My husband was just remarking that though they LOOK cuddly, they are actually very dangerous. And then I look at the footage of little Knut... So many animal advocates said he should have been destroyed, which I don't understand. He seems perfectly happy (I don't get the whole 'better off dead than domesticated' thing, but I'm sure there's a reason).
I have footage of animals at my blog (no politics this week) that you might enjoy. Some interesting behavior...might give you some ideas.The Flatland Almanack --Damozel

Can I claim the little extra blubber on me is for insulating too? LOL- my tt is up now.
