    their individual modes of nutrition. It can be suggested that the foregut fermenters of the marsupials are very similar to the eutherian ruminants, as both types of adaptations are designed to increase fiber digestibility and increase nutrient absorption. However, there are many major differences between the two groups. Ruminants have developed a four-chambered stomach system, which is not seen in the marsupials, as well as a rumination cycle which allows for the rechewing of previously ingested
