Source: Nat Geo. The camel gnawing on a prickly pear cactus. The animals’ tough, flexible lips move over the food, and each half of their split upper lips wiggle independently to get close to the vegetation. As you might be able to imagine, the six-inch needles on the cactus make the plant difficult to chew. So, the inside of a camel’s mouth is lined with raised, cone-shaped structures called papillae. Papillae can be found in the mouths, internal cheeks, and tongues of some species, and they manipulate food to flow in one direction, generally toward the stomach.
