Answer: A giraffe's tongue is colored in shades of blue. This unique hue serves a vital purpose in the giraffe's natural habitat. As these majestic creatures leisurely graze on tall trees and shrubs, their tongues, which can stretch up to 18 inches in length, are constantly exposed to the scorching African sun. The dark blue pigmentation of their tongue acts as a natural sunscreen, shielding it against harmful ultraviolet rays. Other animals with a dark-colored tongue include the polar bear, the impala, the okapi, and the llama. Happy World Giraffe Day!
