polar bear
Another photo of a polar bear from a trip I took to Svalbard after taking early retirement in 2013. I only just noticed the black tongue.
The polar bear's fur is transparent and holds no colour. It only appears white because it reflects visible light. They also have black skin, which is better able to absorb the Sun's energy.
