In general, many say that the word koala comes from the indigenous Australian language, which means not drinking. Koala actually drinking water but is very rare because of the food, eucalyptus leaves, already contains enough water so that the koala does not need to come down from the trees to drink.
Koala can be found along the east coast of Australia from Adelaide to Cape York Peninsula, and as far inland as there is adequate rainfall to support forests suitable for koala.
Physical description.
Koala similar to the wombat (their closest relatives), but has a thicker fur and soft, larger ears, hands and feet longer equipped with a large and long claws to help her climb.The severity varies from 14 kg to a large southern male, up to 5 kg for a small northern female. They are usually silent, but the male koala has a strong tailwind screams that can be heard almost a kilometer in the mating season.
Ecology and behavior.
Koalas live only on eucalyptus leaves. Eucalyptus leaves contain low amounts of protein, undigested substances in high levels, and contain phenol and terpene compounds that are toxic to other species. Such as wombats and lemurs, koalas have a low metabolic rate for a mammal and the rest motionless about 20 hours a day, on most of the time used for sleeping. They eat not depend on time, but usually at night. Koala generally consume 500 grams of eucalyptus leaves per day, chewing them until it becomes a smooth paste before swallowing. Heart separates toxic materials and ready to be discharged, and "hind gut" her (especially cecum) more likely to take the maximum amount of nutrients from food is low quality.Popular culture references.
The popular culture of the West, koala usually described as something innocent and fun to be embraced or as a stubborn old man who was not easily convinced by things around.The series of commercial advertisements, using the airlines Qantas Koala as a character who is always complaining about the reliability of flight.

Koala as a pet.
Although it looks funny, koala is not generally used as pets because the koala does not match the suburban neighborhood. The Australian made koala as a pet is against the law.Fingerprint.
Koala is one of only a few mammals that has a fingerprint. Koala fingerprints are very similar to human fingerprints; even under a microscope, it is very difficult to distinguish between them.Australian researchers Do Research Complete About Koala.
A group of researchers in Australia started researching who claimed to be the most detailed study about animals koala has ever done before. This research took place in the 'capital' koala in Gunnedah, New South Wales.

Gunnedah koala population is believed to have been reduced by more than half since 2008.
It is hoped this research can help to find out what the cause of the drastic decline. This study, among others, will investigate layers of soil and chemical, epidemic disease and koala movement in the region.
Owned mining company China Shenhua contributed funds amounting to $ 180 thousand for this research project. Other funds amounting to $ 400 thousand from the Australian Research Council and $ 30 thousand from the NSW Office of Environment Ministry also available.
The research team led by Dr. Mathew Crowher from the University of Sydney aims to uncover the cause of the decline in koala population.
"Researchers involved will be trying to ascertain what problems does that triggered the drastic decline in the koala population," he told ABC.
Later this research will develop recommendations on how the efforts to restore the animal population.
"We must protect the habitat of koalas and you also have to rehabilitate these habitats," he said.
"This research not only be able to know why koala numbers are declining in the region, but we are also to mitigate this decline in koala populations," said Dr. Crowher.
"We want to know how to rehabilitate the landscape and managing the landscape in the area that became the koala habitat," he added.
Koala, o 'the tree.
Koala is a tree-dwelling mammal that resembles a small bear gray. Koala including the types of marsupials, the female parent has marsupium (pouch). Koala brought her children were immature in the pouch. Koala is a plant-eating animals.The name comes from the Aboriginal koala. The word koala means not drinking. Koala meet 90% of the water needs in the body of eucalyptus leaves. Koala eating eucalyptus leaves and drink only when they are sick or in drought conditions.
The origins of the koala is unknown. So far scientists can only deduce relationships are with other marsupial creatures. Fossil koalas also rarely found. Once upon a time, koala fossils ever found in northern Australia, age approximately 20 million years.
20 million years ago, Australia is a land lush tropical rainforest. It looks koala adapt over millions of years to follow climate change Australia. Another fossil koalas were also found. Uniquely, this is a giant koalas are estimated to live in the south of Australia 50,000 years ago. It looks like a giant koala giant ground sloth in South America.
Koala characteristics.
Koala has a hairy body, soft, and gray or brown on its back. Fur on the belly is white. Koalas living in the south have thicker fur than koalas living in the north. Koala in the northern part inhabit warm climates throughout the year so that it has a thinner fur.Koala has a large hairless nose and round ears. Koala does not have a tail. Koala adult length of 64 to 76 cm with a weight of about 5 to 14 kg. Koala has long claws, powerful, and sharper to climb trees. Front paw has two thumb for grasping branches. The second and third claws are on the back foot.
Koala body shape more or less similar to the wombat, bandicoot is still one relative with a koala. It's just that koala fur is thicker, larger ears and longer legs and arms.
Koala is one of the few mammals that has a fingerprint. Koala fingerprints are similar to humans, even be seen under an electron microscope was still similar. Human fingerprints and koalas are difficult to distinguish.
He is silent nocturnal animals (live active at night). However, male koala like shouting to be heard in the distance of 1 km in the mating season. Female koala koala males measure the size of the volume of the voice screams. They tend to prefer larger males koala.
While under pressure, koala usually screaming and crying, much like a human baby. Koalas living in the wild is unknown period of his life, but koalas who live in captivity can live to the age of 18 years.
Types of Koala.
Koala actually do not have a scientific species variation. However, the Australian koala discriminate based on where his life, where life is different because of different physical characteristics as well. Here it is some kind of koala:1. The typical Victorian Koala.
Because living in southern Australia cooler, Victorian koalas have thicker fur and a long, gray color younger with the back and back of the hand color beige-brown. Brightly colored belly and ears covered with soft white fur.2. Koala typical New South Wales.
Koala who lives in New South Wales has a weight from 8.5 to 12 kg; which means that relatively larger than Victorian koalas. Its fur is thin and soft gray and a bit messy.3. Koala gold.
Koala koala is gold that has little golden color in their feathers. Koala gold is actually an albino koala. He needed (or did not have) the pigment melanin.Koala habitat and food.
Koala inhabits the region of Queensland, New South Wales, Victoria, and South Australia. Habitat varies from coast to eucalyptus forests. Koalas live in groups.Koala is a territorial animal. They require a large area in order to maintain the population and as a means of koala-young koala to expand. Koala communicate with the group by using a sound resembling snoring or burping.
Koalas eat the leaves and shoots of eucalyptus trees. In Australia there are more than 600 species of eucalyptus. However, koalas only eat about 20 species of eucalypts.
In certain areas, there are only three to four species of eucalypts are eaten regularly. Sometimes koala also eat other species and trees or simply used as a bed.
Because very fond of eucalyptus leaves, a koala can stay all day in a eucalyptus tree. Eucalyptus leaves has a low protein content, hard (old) digest, contains phenolic and terpenes are toxic to many species.
Such as wombats and lemurs, koalas have a very slow metabolism. He was a very rare move, could silence for 16-18 hours in a day and most of the beds. Koala can be very aggressive to others. Aggressive attitude shown by their front legs to kick and bite her enemies. Koala is also sometimes involved in a brief scuffle.
5-6 hours a day in the life koala spent on eating. They like to eat at any time, but most often in the evening. In one day, a koala usually takes 500 grams of eucalyptus leaves; chew until really soft and then swallow it. Liver koala can neutralize toxins contained on this leaf.
Koala Life Cycle.
Koala mating season ranges between August and February. In that season, koala males will "shout" to attract females. At that time also, the young koala from the previous year is ready to leave the mother and live independently.After mating, 35 days later, the baby koala is born. Baby koala called a joey. About 2 cm in length with a weight of less than 1 gram. Koala baby body pink, hairless, without ears, and blind. Instinctively, the baby koala will move towards its parent belly and finds its way into the pockets.
Inside the pouch, the baby koala paste mouth on the nipple parent. The nipple is then enlarged in the baby's mouth so that the nipple koala mother will not be released. The female parent is able to tighten the muscles of the stomach pouch openings so the baby koala will not fall out.
After birth, the baby koala is in its mother pouch for 6 or 7 months. Koala baby to suckle its mother from the stomach pouch. At the age of about 22 to 30 weeks, the mother feeding her baby with a kind of porridge that comes from the mother's food, undigested.
It aims to train a baby koala in order to adapt to the actual food, the leaves of eucalyptus. Once out of the pouch, the baby koala hanging on the back of the female parent. However, they are still breastfeeding until the age of one year.
Koala Conservation.
Koala now on the verge of extinction. In the wild, there are only about 100,000 koalas were still alive. Koalas are threatened with extinction due to being hunted in the 20th century for its coat or used as pets. Now, maintaining koala is unlawful. Live koala habitat loss also caused the presence of koala increasingly cornered.To protect it, the Australian government issued an announcement that the koala is no where else in Australia (especially in Queensland and New South Wales) is a protected animal as endangered.
