Diet

Like all camels, Guanacos are herbivores, grazing on grasses, shrubs, herbs, lichens, fungi, cacti, and flowers. The food is swallowed with little chewing and first enters the forestomach to be digested finally after rumination. This process is similar to that of ruminants, to which camels are not zoologically related. The camels' digestive system is likely to have developed independently of ruminants, which is evidenced by the fact that the forestomachs are equipped with glands.
