There the Koalas ranges and territories are usually overlapped and also the Koalas' population density is very high. As the word monogastric suggests, this type of digestive system consists of one ("mono") stomach chamber ("gastric"). The epiglottis stops food from entering the lungs through the trachea. Herbivores are animals whose primary food source is plant-based. The koala ( Phascolarctos cinereus) is an arboreal marsupial that has a unique diet consisting almost exclusively of Eucalyptus leaves.
