Kalluk, Tatqiq, and Chinook will have their own winter wonderland tomorrow, December 6! Snow Day at the Zoo, presented by WowWee AliveTM Cubs, brings mounds of shaved ice as a special treat for the Zoo’s polar bears. See the fun in person or on our Polar Bear Cam!
But don’t expect to be able to tell whether the bears are boys or girls.
Why is it so difficult to distinguish boy polar bears from girl polar bears? Because they’re so furry. The polar bear penis is similar to a dog’s: It is nublike, with a baculum (a bone) that extends when the animal is excited. But long hairs cover polar bears’ reproductive organs, making it hard to determine gender by sight alone. (Even scientists who observe polar bears having sex may find that fur obscures the penis.)
Yes, this entire post is an excuse to type “nublike.”
