koalas generally belong to nocturnal animals, and they are active at night and at dusk, because it can save more water and energy consumption than when the temperature is high during the day.

During the day, I usually curl up and perch on eucalyptus trees, and then go out for activities at night, climbing up and down the branches and looking for eucalyptus leaves to satisfy my hunger. I live in eucalyptus for most of my life, but occasionally I fall to the ground because I change my habitat trees or swallow gravel that helps digestion.

They feed on eucalyptus leaves and twigs, and eucalyptus leaves are their only food. They hardly ever drink water in the fields because they can get enough water from eucalyptus leaves.

Their livers are very peculiar and can separate toxic substances from eucalyptus leaves, so koalas sleep for a long time to digest toxic substances. They need to sleep for 17-2 hours every day, leaving only 4 hours for food intake, activities, personal hygiene and communication with other koalas.

koalas are gentle and slow, and never pose a threat to other animals. The koala is very slow, and the reflex arc of this animal seems to be particularly long. Someone once tried to pinch the koala with their hands, and it took a long time for the koala to scream.

koalas have a well-developed nose, which can easily distinguish different kinds of eucalyptus leaves, find out which ones are edible and which ones are poisonous but not edible, and can also smell the warning smell left by other koalas.

koalas make various sounds to communicate with other koalas. Male koalas mainly show their dominance and dominance by roaring, so as to avoid energy consumption in fighting and show their position to other animals.

koalas can tell at a glance whether a tree belongs to them or to other koalas. Koalas leave their own globular droppings at the base of trees.

The living conditions of koalas in Australia are worrying:

The naive koalas are known as Australia's national treasures, which are mainly distributed in low-altitude and sparse eucalyptus forests in Queensland, New South Wales, Victoria and South Australia.

The natural enemies that koalas face in nature are mainly Australian wild dogs, foxes and eagles. However, human beings are increasingly becoming the number one killer threatening koalas' lives.

the koala foundation of Australia estimates that there were more than 1 million koalas in Australia before the British set foot in Australia in the late 18th century. At present, the number of wild koalas in Australia is less than 8,.

The loss and fragmentation of koala habitat caused by human activities is the biggest threat to koala population. The progress of urbanization in Australia's coastal areas and human activities such as jungle reclamation in inland areas have directly led to a sharp decline in the number of koalas.

Due to habitat loss, the koala population in Queensland has decreased by 53% and that in New South Wales by 26% in the past 15 to 2 years.

The destruction of habitats forced koalas to migrate to find new habitats. In this process, koalas are vulnerable to the impact of traffic and the attack of domestic dogs. At present, more than 4, koalas die every year under the wheels and attacked by domestic dogs.

An animal hospital in Queensland claims that more than 1, injured koalas were treated last year. Although the hospital has tried its best, it is still overwhelmed, and the continuous expansion of the city is the main factor for the sharp increase in the hospitalization rate of koalas.
