What is the approximate length of a giraffe's tongue in centimeters?

The average length of a giraffe's tongue is indeed about 50 centimeters. Giraffes have long, prehensile tongues that help them reach leaves and shoots high up in trees, which is essential for their feeding habits. The dark coloration of the tongue, which can appear bluish or purplish, helps protect it from sunburn as they spend a lot of time with their tongues extended while foraging. This length is specifically advantageous for giraffes, allowing them to easily grasp and pull foliage into their mouths. The other options, while close, do not accurately reflect the commonly accepted measurement for a giraffe's tongue.
