The dromedary camel is distinguished from other camelids by the single hump on its back. This mound of fat can grow up to eight inches high. Watching them eat is fun but inside the mouth is scary. They have a series of raised pink structures resembling needles called papillae. These manipulate food while protecting the mouth and some contain taste buds. Many of their 32 teeth are enormous with yellow enamel and their lower jaw swings side to side. The result is not pretty but it is effective for consuming their main diet of grass and foliage.
