koalas live in the open eucalyptus forest, and spend most of their lives on eucalyptus trees. You can eat a lot of eucalyptus leaves every day and digest them well. Koalas' teeth are suitable for processing eucalyptus leaves. They chew the leaves into a fine paste with molars, and then these things will be fermented by microorganisms in the cecum. An adult koala eats about 5 grams of fresh leaves every day.

Koalas' habitat

Koalas are endemic to Australia, distributed in southeastern Queensland, eastern New South Wales, southeastern South Australia and Victoria. Koalas are solitary animals, and males who are used to settling down occupy a fixed nest area. The size of the nest area is related to the product richness of the habitat environment.

In the south with abundant products, the nest area is relatively small, with the male occupying .15-.3 square kilometers and the female occupying .5-.1 square kilometers; However, in semi-arid areas, the nest area is much larger, and males often occupy 1 square kilometer or more. The nesting areas of socially dominant males overlap with the nesting areas of up to 9 females.
