The Gray koalas, as the name suggest have a gray colored fur on their bodies. Their health and natural environment, however, have been under threat for a long time. Therefore, fertile lands are the core preference for spotting Koalas' habitat. The average ages of the female Koalas are around 16 to 17 years. They rarely drink water and rely on their food for water. Koalas like a change, too, and sometimes they will eat from other trees such as wattle, tea tree or paperbark. A DNA sequence derived from a retrovirus is present in different numbers and sites in different koala populations, testifying to its recent movement and amplification. The Eucalyptus leaves offer lower nutritional value for koalas and it is just a miracle that koalas rely on the Eucalyptus leaves during their entire lifespan. 34.2: Digestive Systems - Herbivores, Omnivores, and Carnivores Normally all the babies of the Marsupials are called as Joeys. All mammals have teeth and can chew their food. Climate change is also contributing to the decline of koalas.

Comparisons of digestive tract anatomy. How koalas exist on an exclusive low-calorie and toxin-laced diet of eucalyptus leaves has been somewhat of a science mystery. It wouldn't be wrong to consider them as defenseless. Koalas' each tooth grows steadily, however, after some time, because of grinding and combination of poisons and toxicants in Koalas food, their tooth decay starts.
