What color is a polar bear's skin?
I have read repeatedly that polar bears are supposed to have a black hide under their fur. Their fur consists of tiny little tubes which act as very efficient fiber optic light pipes to capture sunlight and deliver it to the polar bear's skin, which is supposedly black to absorb the heat better. However, when I have encountered preserved polar bear hides in museums. the skin appears light brown. What is the reason for this? Did the skin lose pigmentation during the curing/preserving process? Did I just encounter hides from albino polar bears? Is the theory wrong?

- Their skin is brown. They have two layers of hair, one black and one white.
- ive heard it before that the color of a polar bear is white...
- You're probably right, I've heard the same thing.
- Black
- Their skin in black and their hair is like a fiber optic, channeling light and therefor heat to their black skin.
- They have 'dark' skin. Their hair is hollow to help capture heat. Maybe they are losing color after death?
- That a polar bear's skin color is actually black is correct. Any discoloring that you have seen may have been to drying or preservation effects on the carcass.
- Its white and brown!!!
