Polar Bear Trivia

  • Today, I will share some trivia about polar bears.


    The polar bear looks white, but the skin color is actually black, and the hair color is transparent.

    If the body hair color is transparent, the heat of the sun will be absorbed effectively because light is transmitted easily through the hair.

    Furthermore, the inside of the hair is hollow, and light is scattered, so it looks white, and it has an heat accumulation effect.

    Since the body temperature of the polar bear is hardly released, there are very little infrared light that is radiated from the body, and it’s really difficult to capture the figure using an infrared camera.

    Also, the body hair, which looks white, plays a role of protective coloration, and polar bears seem to hide their black noses when they have a hunt.
