Due to sleepy Blake trying to convince me that there was polar bears in Antartica and they eat penguins, first "I got nothing, have facts and gifs" blog is on polar bears >>;

 

Polar Bears aren't really white. I'm like 90% sure everyone knows this one, but still. Their fur is colourless, and their skin black, and the white is from light reflecting off of the hollow pockets of hair inside each guard hair ouo

Their fur actually insulates them so well that they're more at risk of overheating than freezing.

Another thing about their fur? It makes them invisible to infrared cameras. They're so well insulated that they give off the same heat signature as the snow around them, save for their breath, nose and eyes.

Stealth mode activated.

The largest record polar bear weighed one ton. (2209 pounds for you crazy non-metric folks)

Keeping captive polar bears isn't a new thing either. The ancient Romans included them among the exotic animals for their gladiator sports, and Henry III kept a pet polar bear, which lived in the Tower of London, was led down to the Thames River to hunt for fish periodically, and came complete with a Norwegian keeper, courtesy of King Haakon of Norway.

They're amazing swimmers at 10kph / 6mph, and capable of going nonstop for over a week. As the sea ice melts they have to travel larger and larger distances to find land - the record is held by one female who crossed 687km / 426 miles in nine days. Her cub died during the swim, and she lost 22% of her body weight, something that will only become more common as the ice continues to melt.

Errrrmmmm, something less depressing than that... There are polar bear-grizzly hybrids? As the polar bears are forced south by the loss of ice, some are interbreeding with grizzly bear populations, producing fertile hybrids (as opposed to how many other cross-species offspring are infertile).

Which is awesome / terrifying. These hybrids aren't as suited to the Artic as polar bears, being less able swimmers and less suited to walking on ice, but may be better equipped to live on land.

 

Well, I think I've run out of facts but still have a few more gifs, so that'll do for this blog entry? Next one will either be an animal one or me having a rant about radical feminists and my adventures in finding out what TERFs and SWERFs are. Or maybe talking about games, idk.

So yeah. Bye guys!

Wow i didnt know about a lot of this stuff.  The interbreeding is wack.

My mom loves polar bears.  I am buying her a polar bear cookie jar for her birthday in two weeks.

Polar Bears also like to drink Coca Cola.  I saw it on TV. :)

No, actually I tried to convince you they were grumpy because their home was flooded and they didn't have insurance. You never listen :p

That was a fun read Bilbs. I like polar bears, but not as much as pandas. :)

You could do a panda blog next.

I want to play with those bears. Adult polar bears are enormous though and could accidentally kill a person quite easily.. Too bad they hunt and kill other animals I like. What a world.

Radical feminists on horseback, there's a blog I'd like to read.
