The koala is a marsupial that lives in Australia, they belong to the family of wombats in the order Anuranidae and are one of the oldest marsupials in the world.

The koala has a cylindrical body with a rounded head, small ears, large, round eyes, soft, gray, or brown fur, and shorter, sparser fur on the lower part of the body.

Koalas have longer forelimbs than hindlimbs and their thumbs can be separated from the other four fingers to facilitate their climbing of trees.

The koala's main diet is eucalyptus leaves and shoots, a rare food item, so koalas spend most of their time resting and digesting their food.

The koala is one of Australia's iconic animals and one of the most popular animals in the world.

The koala is Australia's national treasure and is featured in almost every Australian tourist promotion, attracting many visitors to Australia each year to see koalas.

With a history dating back some 25 million years, the koala is one of the oldest mammals on the planet. The ancestors of the koala were large marsupials, which differed greatly in size from the modern koala, weighing several tons.

Over time, this large animal evolved into the modern koala, which adapted to the Australian environment and developed a unique way of life.

Koalas live mainly in the forests and bushland of eastern Australia, where they prefer to live and move around in the trees. The koala is a nocturnal animal and spends most of the day in the trees sleeping and digesting its food.

Koalas have a very special digestive system and they spend a lot of time digesting their food. Koalas have a special bacteria in their gut that helps them digest the cellulose and lignin in eucalyptus leaves.

Koalas need to consume large amounts of eucalyptus leaves each day to get enough nutrients.

Koalas are very docile animals and they do not usually attack humans. However, when observing koalas in the wild, it is important to keep a distance and avoid disturbing them.

The destruction of koala habitats and disturbance by human activities threaten the survival and reproduction of koalas. To protect koalas, the Australian government has put in place measures to prohibit the hunting and killing of koalas and has established koala sanctuaries to help koalas survive and thrive.

Overall, koalas are a very special animal with a very unique lifestyle and digestive system. Koalas are not only Australia's national treasure but also one of the world's most popular animals.

The survival of koalas is under threat and we need to protect these lovely animals and allow them to live and breed freely in the forests of Australia.
