It helps Koala Joeys to spot their mothers' pouch and also teats as well to detect milk within the pouch. Stomach. Herbivores are animals whose primary food source is plant-based. The process is somewhat similar to the rumination process within the herbivore mammals. Even though Kangaroos are popular as Australia's national animals, but yet still Koalas still enjoy more popularity because of their cuteness and cuddliness. This phenomenon is very strange as both the male and female koalas almost habitat on the same food within any territory. It can be seen that the human digestive tract is relatively small.
