Do you know what color is a polar bear tongue? The polar bear tongue is actually pink and it is mottled with black that is why it sometimes looks black or even blue. The general properties of its tongue resemble dogs more than the cats. The polar bear tongue is smooth just like the dog’s tongue. Cats do not have a smooth tongue.
