Inside Nature's Giants - Polar Bear

Continuing with their exploration of the anatomy and physiology of the giants of nature, the team travels to the North Pole in search of a polar bear: the largest land mammalian predator in the world. Because of the difficulties of finding polar bears at all, never mind fresh carcasses, this episode requires the collaboration of a local hunting community whose survival depends on using every last scrap of these animals without wasting anything. And because of the weather conditions, every move is a race against the freezing clock.

Now, the first and most obvious question is just how these bears manage to withstand the intense freezing temperatures of their natural habitat. The answer, it turns out, and this should throw you for a loop, is that a polar bear is a black animal with transparent fur that looks (but isn't) white. Yeah, I was floored too.

But that's not the whole story. We also get to understand, among other things, exactly why there are polar bears to begin with and how they manage to cope with diets that would literally kill us.

Did you see the polar bear attacking that walrus that was probably twice its size?!?
