What color is the polar bear actually

I am sure that most of you have never thought about this. The polar bear in the human mind is white by default. And no other way. But actually it is not! And here it’s not even talking about the fact that it can be gray or yellow, everything is much more radical!

The skin of a polar bear is black. Yes Yes exactly. I am not confusing anything. As it usually happens in nature, the color for the skin was not chosen by chance. We are all well aware that the black surface is better than others in the sun. And that is why polar bears are black.

I think that, most likely, you just thought: "What does the author carry and how, with such a thick white skin, do the sun's rays fall on black skin?"

And here everything is also very simple: the hairs in the skin of a polar bear are actually hollow and the sun's rays easily reach the skin through them. Such is the analogue of fiber optic cable in the wild.
