The Color of a Polar Bear's Skin
What Color Is a Polar Bear's Skin?
A polar bear's skin is black. That's right - black! Despite their stunning white fur, polar bear skin is a dark color. This is because the skin underneath their fur absorbs and retains more heat than white skin. This helps them to stay warm in their cold Arctic environment.
Why Are Their Fur and Skin Different Colors?
The fur of a polar bear is actually transparent. While the fur appears white, the transparent hair shafts are filled with air, allowing sunlight to pass through them and reflect back off the snow. This creates the illusion of white fur – but the fur itself is actually clear. The skin, however, is black due to its higher ability to retain heat.
Do All Polar Bears Have the Same Skin Color?
No. Polar bear skin color can vary depending on their environment and the amount of sunlight they receive. Polar bear skin can range from a dark gray to a dark brown. But regardless of the shade, the skin is always darker than the fur.
Do Polar Bears Use Their Skin Color to Camouflage?
No. Polar bears are not trying to blend into their environment, as they are the top predator in the Arctic. Instead, they rely on their white fur to blend in with the snow and ice. This helps them to remain undetected by prey, as well as other predators.
