They have nothing in common with teddy bears.

Koalas are very distinctive animals found only in Australia. They are known for their calm temperament. They live peacefully in the treetops, where they are protected from the danger of predators. They are endangered and need our help. The last major threat to this species was the huge fires that hit Australia in early 2020.


The Australian koala is the only living member of the koala family.

Contrary to popular belief, they have nothing to do with bears other than being mammals.

They live in eastern Australia and southern Victoria.

Their distribution area is only 1 million km2. In many parts of the continent they were extirpated and reintroduced in the second half of the XNUMXth century.

They live in open forests in tropical and temperate climates.

In hotter areas, they live near rivers and streams, where they retreat during extreme heat and drought.

Koalas are medium-sized mammals with a stocky body and a large head.

Adults reach sizes from 60 to 85 centimeters and weight from 4 to 15 kg. This makes them one of the largest arboreal marsupials.

Males are approximately 50% larger than females.

In addition to body size, males and females can be distinguished by their more rounded nose.

Their brains are very small and underdeveloped.

Of all mammals, the koala's brain is one of the smallest relative to its body weight. In addition, their cerebral cortex is not very folded and occupies only 61% of the surface of the skull.

They are herbivores and their favorite food is eucalyptus.

They can only digest the leaves of selected plant species. Most of their diet consists of eucalyptus leaves, but they also eat acacia, cypress and some other Australian plants. In the case of eucalyptus, they are quite picky, since out of the 600 available species of this plant, they choose about 30. They eat about 400 grams of leaves per day, usually in six separate meals.

They sleep up to 20 hours a day.

This is due to their diet, which is low in calories and forces koalas to conserve energy.

Koalas are active at night.

They spend most of their activity on the tree and feed during this time. It often happens that a koala sleeps and feeds in the same tree for XNUMX hours a day.

To cool off on hot days, koalas descend to the lower parts of trees and press their bellies against the branches.

During cold and wet periods, they curl into a tight ball to conserve energy.

Koalas live in small groups consisting of a male and several females, and in some cases - alone.

Their population is divided into “residents” and “guests”. The former live in this area permanently and are most often the dominant individuals. Visitors usually stay with a group of koalas for a while and then leave.

Although koalas create small social structures, they are solitary animals.

They spend no more than 15 minutes a day on social interactions.

Although female koalas often mark their fertile period through body language, male koalas may not always notice and will sometimes mate with infertile females.

It is the males who initiate copulation, sometimes even by force, since they are much larger than the females. The female may resist and make loud noises that will attract other males nearby. Then, before copulation, the male must drive away rivals and during fights the female has the opportunity to choose the dominant male. Ultimately, he is in any case subordinate to the dominant or most famous member of the opposite sex.

The mating season of these animals lasts from October to May.

After a gestation of 33 to 35 days, a single blind and hairless cub is born (in very rare cases, two cubs are born).

Young koalas grow in their mother's pouch for 6 months.

For the first 5 months they feed on their mother's milk, and after this period they feed on food partially digested by the mother from her intestines.

The koala is fully protected as it is considered a critically endangered species.

Protection of these animals was introduced in 1927. The factor that most threatens koalas is the prevailing drought.
