Is Australia's national treasure, but also Australia's unique precious primitive arboreal animals. English koala? Bear comes from the ancient aboriginal writing, which means "no drinking". Because koalas get 90% of the water they need from eucalyptus leaves, they only drink water when they are sick and dry. The locals call it "Kwale", which means "no water".

Extended data:

Koalas generally belong to Nocturnal Animals. They are active at night and 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, and then go out for activities at night, climb up and down the branches and look for eucalyptus leaves to satisfy my hunger.

I have lived under eucalyptus trees for most of my life, but occasionally I fall to the ground because of changing habitat trees or swallowing gravel to help digestion. Feeding on eucalyptus leaves and branches, eucalyptus leaves are their only food. They almost never 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 17 ~ 20 hours every day, leaving only 4 hours for feeding, activities, personal hygiene and communication with other koalas.
