Giraffe

The giraffe's tongue is about 50 cm (20 in) long and prehensile. It is purplish-black in color, perhaps to protect against sunburn, and is useful to gripping branches and stripping leaves as well as for grooming and cleaning the animal's nose. The upper lip of the giraffe is also prehensile and can grasp foliage. The lips, tongue and inside of the mouth are covered in papillae to protect against thorns.
