Last we heard a 'polar bear' is a warmly older guy with some snow on the roof -- and some on his chest as well: a silver-haired daddy-bear, in other words.  Now usually these fun white-haired daddies are easy to tell apart from, say, regular bears ... and especially girls.

Boy or Girl?

But it seems that with real polar bears it's a bit harder to tell girls from boys, just ask the staff of the Kushiro Municipal Zoo in Japan.  Seems they've been trying to get Tsuyoshi and Kurumi, two star polar bears, to mate - always unsuccessfully.  And no wonder: Tsuyoshi and Kurumi are both girl bears.

Apparently, with polar bears, separating the men from the errrr.... girls is more difficult than one might think.  We sincerely wish the staff of the zoo the best of luck in finding a male bear for Tsuyoshi and Kurumi.  Lucky for us, our kind of polar bears are pretty easy to spot -- and as for mating ... buy us dinner first and we'll talk.
