Do polar bears have black hair?
1. Why do polar bears have white fur? Interestingly, the polar bear’s coat has no white pigment; in fact, a polar bear’s skin is black and its hairs are hollow. They have a thick layer of body fat, which keeps them warm while swimming, and a double-layered coat that insulates them from the cold Arctic air.
Why are polar bears black?
The outer layer of hair is clear – and a polar bear’s skin is black. Polar bears evolved to have black skin, as the colour is the best for absorbing energy from the sun. The clear fur allows this sunlight to get to the skin – but it still looks white, so that the bear can blend in with its environment of ice and snow.
How did polar bears get 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.
