The abrasions form tiny holes in their hairs, opening a gateway for algae that can live and breed inside. In the Arctic, temperatures are too cold for these algae. But wild polar bear fur can still change color to yellow, thanks to oils from their prey that stain the fur.
Do polar bears have black fur?
2. Polar bears are actually black, not white. Polar bear fur is translucent, and only appears white because it reflects visible light. Beneath all that thick fur, their skin is jet black.
How do polar bears have white fur?
Polar bear hair shafts are actually hollow, which allows the fur to reflect back the light of the sun. Much like ice, this reflection is what allows these bears to appear white or even yellow at times. In a warmer environment (like in a zoo), algae can actually grow inside these tiny hollow hairs.
What makes polar bears white?
Unlike human hair, polar bear fur is hollow like a straw. These tubes are too small to see without a microscope, but there’s enough room for light to scatter inside. When the bears stand in the sun and all that light bounces off them, they look white.

How does the polar bear’s fur color help them survive?
Beneath this light colored fur though, lies the skin of a polar bear which is black in color; and that helps the species absorb heat from the surroundings. More importantly, the dense fur coat of this species is made up of thick, hollow fur which helps it survive the freezing cold climate – a characteristic trait of this region.
Are polar bears black under their fur?
But under their fur, polar bears have black skin—the better to soak in the sun’s warming rays. These powerful predators typically prey on seals. In search of this quarry they frequent areas of shifting, cracking ice where seals may surface to breathe air. They also stalk ice edges and breathing holes.
