The strong jaw and large canines permit the dingo to procure and machinate rather tough prey, allowing . Larger Food particles Are Excreted via Large Intestine Learn interesting features about the koalas nose. Their digestive system is similar in working to other animals because just like all herbivores, koalas first chew their food, pass them to their stomach from where it first goes to the small intestine and then to caecum and finally to the large intestine for excretion. There are many factors for Koalas' Starvation. As the word monogastric suggests, this type of digestive system consists of one ("mono") stomach chamber ("gastric"). At the time of their birth baby Koala joeys are just around 19 millimeters. Maintaining genetic diversity is important because different animals can mount different responses to environmental threats and diseases such as chlamydia, a bacteria that affects koala reproduction and eye health.
