Koalas, one of the most lazy and cute animals of the world, are herbivorous, marsupial animals living in Australia. Although the name Koala is commonly expressed in the Aboriginal language, it does not support it. Because the Koalas drink water very rarely. Eucalyptus leaves that make up the main nutrients of the koalas meet the basic water needs of the kolas. They only need water during drought periods when there is not enough moisture in the leaves and when they get sick.
In Australia, almost everyone comes to mind kangaroos that leap their heads with their offspring. Koala is also like a kangaroo; but people used to think that they were a bear species. Indeed, if you look at the old resources, you may find the koala bear name instead of the koala. Koalas look like a really cute little bear. But they are very different from them and they are a marsupial type. In other words, we can say that the offspring were born prematurely and settled in their mother’s bladder.
The duration of pregnancy is 35 days. The baby born at the end of this period is 2 cm tall and weighs 5 grams. Hairless and blindfolded offspring of the help of her mother’s back to the pose of the climbs into the opening. She clings to the nipple of the mother as soon as she climbs into the bag. But since it is much smaller breast milk Instead, the mother koala drains milk from the milk glands to the pup’s mouth. The puppy stays in the cuts until the feathers and the arms that they use to climb in the future develop. This maturation period is about 5 months. The pup is reborn at the end of this period! He lives on his mother’s back, clinging to his now growing arm until he is one year old. It should take three years for koalas to grow fully.
Eucalyptus leaves contain high amounts of fiber and very little protein. These leaves have strong odorous oils, phenolic compounds and cyanide substances which are not even edible or poisonous for many mammals. These substances, which are harmful to other animals, lose the poison effect in the body of the coals. Because koala has a digestive system with a very special anatomy and physiology. It can be said that Biochemical Factory with this property.
Like other herbivorous mammals, koala cannot digest cellulose, the main ingredient of eucalyptus. However, they do micro-organisms that can digest cellulose and live in the mollusk of the coalan. This blind intestine opens into the large intestine and is quite large. Thus, the blind intestine constitutes one fifth of the total bowel length. The blind intestine is the most interesting part of the digestive system of the coals. The passage of the leaves through the digestive system is delayed here. Thanks to this delay, micro-organisms in the gnaws become active and make cellulose to benefit the coals. In this case, the blind intestine of the cochlea can be compared to a biochemical factory. While cellulose is processed in this factory, oils and toxic chemicals (phenol compounds) are inactivated by infiltrating the liver in another factory.
At the end of these three years, koala, who can survive on its own, is fed with eucalyptus leaves. There are 600 kinds of eucalyptus trees in the region where the koalas live. But it is known that the koalas only enjoy 120 different types of eucalyptus. Eucalyptus tree is both their food and their home. They never get down unless they really need to. In fact, they just hit the ground to move from one tree to another. They drink almost no water. They sleep mostly during the day. Forks in the branches of eucalyptus are the most beautiful beds in the world for them. Koala sleeps 18 hours a day. While he gives the impression that he is too lazy to sleep with a lazy animal, it is only because of his eating habits. The energy they provide from the leaves they eat is only sufficient for the koalas to move from one tree to another. The energy in the leaves is obtained by digesting them in the digestive system. Such a common life would benefit both the microbes and the coin. Nevertheless, we can say that the offspring of koalas are sufficiently mobile and actors, just like their offspring of other mammals.
The only food source of the coals is eucalyptus leaves. This means that the animal needs to meet the carbohydrate requirement by microorganisms digesting the cellulose. This is clear proof that it is not possible for koalas to live without microorganisms.
the koalas who have no jobs other than labor and sleeping are now protected by law. Thanks to these laws, koala hunt is now prohibited. Between 1860 and 1920, the number of koalas hunting for their furs was greatly reduced. The fact that in 1927 600,000 koala furs were taken out of Australia is a sign of how many times they were hunting. Today, the number of koalas in Australia is estimated to be between 40 000 and 80 000. In short, they were hunted for their fur for years. 80% of the forests in which they live were destroyed by the white people who settled in Australia.
When they looked at these cute, delicate animals, people always wanted to feed them at home; but it wasn’t until they thought that separating this creature from the forests of Australia, which had their own wild environments, into a marsupial group, would make them unhappy. Even if we see them in zoos, we must make them live in their own wild environment where they will be happier. We can do this only when we fully gain our sensitivity to protect nature. This also applies to all other species of life that we destroy. Many living species in the world lose their living environment. Therefore, many species on Earth face danger of extinction.
