Herbivores such as cows, koalas and kangaroos have a symbiotic partnership with these organisms. Koalas have been occasionally spotted on other trees as well and eating different leaves rather than Eucalyptus.

The stomach is used for storing, mixing and liquefying food and regulating its entry into the small intestine. The six activities involved in this process are ingestion, motility, mechanical digestion, chemical digestion, absorption, and defecation. During Summers Koalas may prefer slightly more fluid and water contents within Eucalyptus leaves, while in winters they might prefer less fluid and water contents. Finally dry leaves lack proper nutrition for the Koalas. Knowing the full set of koala genes deepens our knowledge of koalas (and other Australian mammals) in many ways. The koala digestive system is unlike that of most other animals.
