Koalas are extremely picky with their food, but will occasionally branch out (literally) and eat from other Australian natives. Copy. As the word monogastric suggests, this type of digestive system consists of one ("mono") stomach chamber ("gastric"). Whenever, the young Koala Joeys grow up, female Koalas do become aggressive towards them. This type of relationship is called a mutualism relationship. Therefore; the process of merycism specifically helps koalas to have proper digestion and extract maximum energy from the finely chewed Eucalyptus leaves. Marsupial females having a pouch is the key differentiation when compared with the females of Placental Mammals. The origin of the Marsupial animals goes back to almost 125 million years.
