Living habits of koalas

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, 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.

Koalas are gentle and slow-moving and never pose a threat to other animals. Koalas are slow, and the reflex arc of this animal seems to be particularly long. Someone once tried to pinch the koala with his hand, and it took a long time for the koala to scream.

Koalas have a well-developed nose, so they can easily distinguish different kinds of eucalyptus leaves, find out which are edible and which are poisonous but inedible, and smell the warning smells left by other koalas. Koalas make various sounds to communicate with other koalas. Male koalas mainly show their dominance and desire by roaring, so as to avoid consuming energy in the battle and show their position to other animals.

Koalas can tell at a glance whether a tree is their own or that of other koalas. Koalas will leave their own small spherical excrement at the bottom of the tree; Even one year after the death of a koala, other koalas will not move into this empty home, because during this time, the smell traces and claws left by koalas have not naturally weathered away.

When the young koala is sexually mature, it must leave its mother's home and find its own field. Its goal is to find and join another breeding population, which is more important than finding a habitable habitat. There are always some male koalas temporarily wandering outside the stable population, often staying on the edge of the breeding population, waiting to join them and become permanent residents.

Whether it is day or night, koalas will naturally assume different sitting and sleeping positions in the safe family tree, and at the same time, they will constantly move their positions on the tree because of avoiding the sun or enjoying the breeze. In hot weather, koalas spread their limbs and sway slightly to keep cool, while in cold weather, they huddle up to keep warm.
