Trivia: What type of bear has transparent fur?
Koala bear
Polar bear
Grizzly bear
Panda bear
The correct answer is Polar bear
So why is this answer correct? : While polar bear fur appears white, this is a bit of an illusion: Their fur is actually transparent, and their skin underneath is black. Each hair in a polar bear’s coat is hollow, and while these little tubes are microscopic, they cause all the colors in light to scatter, making them appear bright white. In fact, in other environments or weather conditions, polar bears can appear gray, yellow, and even orange.
