How long, in inches, is a giraffe's tongue?

The length of a giraffe's tongue is notably long and can extend around 20 inches. This unique feature serves multiple purposes; primarily, it allows giraffes to reach high leaves and branches that other animals cannot, making it an essential adaptation for their survival in the wild. Their long tongues are also prehensile, meaning they can grasp and manipulate objects, which helps them strip leaves from trees efficiently. This length not only highlights the giraffe's evolutionary adaptations but also plays a significant role in its feeding behavior. Therefore, the choice of 20 inches accurately reflects the average length of a giraffe's tongue, making it the correct answer.
