what colour is a giraffes tongue

The color of a giraffes tongue is best described as black, blue, or purple with a pink base or back. The front part of the tongue has such dark coloration to protect it during frequent sun exposure while eating and prevent the tongue from getting sunburned. The back and base of the tongue are pink in color. This unique coloration is due to the presence of melanin, which acts as a natural sunscreen, helping to protect the giraffes tongue from the suns harmful rays.
