Which animal's tongue is so long that it is anchored to its sternum?

The animal with a tongue so long that it is anchored to its sternum is the giraffe. This adaptation allows giraffes to reach high leaves and branches in trees while feeding. Their tongues can be up to 20 inches long and are prehensile, aiding in grasping foliage. This unique feature is essential for their survival in their natural habitat.
