The koala is a herbivorous marsupial animal, it belongs to the koala family, the order of two-incisors. Koalas are mammals, they look like cubs in appearance, so Australian settlers called this animal the koala bear or sac bear. This name is still used today, although these animals have nothing in common with a bear.
The body length of the koala ranges from 60 to 80 cm, its weight is 5 - 15 kg. (depending on climate). The animals have a large round head and fluffy ears. They have rather long paws with tenacious claws. There is a papillary pattern on the koala's fingertips, its prints are similar to human ones. These “cubs” have thick gray or gray-brown fur and a lighter belly. Koalas do not have a tail. The paws of animals with fingers set to the side and sharp claws are perfectly adapted for climbing trees. The animals sleep on the tree and can hold onto the branches even with one paw.
The female koala has a pouch on her belly for her baby. These animals breed once every two years. There are more females than males, so during the mating season the male has a harem of 3-5 females. A newborn animal climbs into its mother’s pouch, where it is warm and has milk.
Koalas are nocturnal animals and live in trees. Calm and slow bears can sleep up to 20 hours during the day. But these animals can climb trees well, swim and deftly jump from tree to tree. In case of danger, the koala can gallop and quickly climb a tree.

Koalas live in eucalyptus forests, the leaves of which are eaten. These animals have adapted to feed exclusively on eucalyptus. It is fibrous and contains a lot of protein. But the disadvantage of this plant is that eucalyptus contains phenolic and terpene compounds that are poisonous to most animals. Besides koalas, the only animals that eat eucalyptus are the ring-tailed glider and the marsupial flying squirrel. There are many types of eucalyptus growing in Australia, but koalas only choose the edible ones. The animal eats up to one kilogram of leaves per day. Koalas do not drink water; they get it from eucalyptus leaves.
Local predators do not eat koalas, as their meat is soaked in eucalyptus. They can only be threatened by wild dogs. But slow and trusting koala bears have become easy prey for hunters. They were killed to obtain the thick, valuable fur of these animals. Koalas were also threatened by deforestation of eucalyptus forests and Forest fires. All this led to a reduction in the number of animals. The Australian government has banned koala hunting and opened koala reserves. Now their population is gradually recovering thanks to free living in their natural habitat.

Scientists have found that koalas, hanging on trees for hours, use tree trunks as refrigerators. Australian researchers from the University of Melbourne came to this conclusion. Observations also showed that in the heat, koalas prefer to hang on acacia trees rather than eucalyptus trees.

Animals during extreme heat descended into bottom part tree, where the trunk and branches are the coldest and the whole body pressed against them. Gradually, the koalas' body temperature dropped.
The study was published in the Royal Society journal Biology Letters. Scientists from the University of Melbourne used thermal imaging cameras to capture images of koalas descending to cooler parts of a tree in hot weather.
For example, when the air temperature reached 39 degrees, the temperature of the tree trunk was at least seven degrees lower.
“This got us thinking that koalas might be using trees as a heat sink,” said University of Melbourne professor Michael Kearney.
A similar observation was made by graduate student Natalie Brusco, who studied the behavior of koalas. In winter, animals are more likely to sit in the treetops near the leaves they eat, she said. In summer, koalas descend lower.
The koala (Phascolarctos cinereus) is a tree-walking herbivorous marsupial native to Australia. The only representative of the Koala family. They live in coastal areas in eastern and southern Australia, from Adelaide to the southern part of Cape York Peninsula, as well as on Kangaroo Island, where they were introduced in the early 20th century. They are also common in regions with enough moisture to support forests suitable for koalas. South Australia's koalas were largely wiped out during the first half of the 20th century, but with the help of individuals from Victoria, the koala population in South Australia has been restored.
Although koalas are not bears, they were called koala bears by English-speaking settlers of the late 18th century due to the similarity between koalas and bears. Although taxonomically incorrect, the name "koala bear" is still used outside Australia, but its use is discouraged due to inaccuracy in the name. Other names for this animal in English language, based on the word "bear" were "monkey bear", "native bear" and "tree bear".

Today we have prepared for you Interesting Facts about koalas, which will tell you about the amazing and funny marsupials that live in Australia.
Koalas are mistakenly called bears because of their external resemblance, although these animals have nothing to do with bears. The ancestors of koalas lived on Earth 34 million years ago.
The name koala comes from the Darak word gula, which was spelled koala in English. The Latin name of the genus koala comes from Greek words"bag" and "bear".
Although the name koala has been erroneously translated as "an animal that does not drink water", koalas are now increasingly coming into contact with people in search of water, especially during forest fires.
The weight of an adult koala can reach 15 kg and height - 80 cm.
A baby koala spends the first six months of its life in its mother's pouch. A newborn baby weighs only 3-5 grams.
Koalas have absolutely no time for games and entertainment, because they spend about 18 hours a day resting. The rest of the time, at night, they look for food. Koalas lead a solitary lifestyle.
But, by the way, despite their slowness and clumsy appearance, koalas quickly jump from one tree to another. And they swim well when they have to escape from danger, or just to freshen up.
According to research, koalas have an excellent sense of smell, which is many times better than their vision. They can smell different types eucalyptus trees that contain different quantity toxin.
In Australia, with the development of infrastructure, the authorities decided to prevent the death of animals under the wheels of cars. in an unusual way. Artificial vines connecting eucalyptus trees are stretched over the roads. Koalas willingly cross the road using these ropes.
Koala fingerprints are absolutely indistinguishable from human fingerprints, even when viewed under an electron microscope.
To prevent the baby in the mother’s pouch from getting hurt when the mother koala climbs trees, the “entrance” to her pouch is located not at the top, like a kangaroo’s, but at the bottom.
Although koalas are not aggressive animals, during the mating season the males start real wars among themselves and make loud noises.
In fact, in these times of disasters, when forest fires occur in the forests, koalas often come to people for water, as happened during the fires in Australia in 2009.
