Koalas
Native to Australia and exclusive to the eucalypt forests of Eastern and South-Eastern Australia, there are only three subspecies of Koala. Solitary animals, Koalas sleep as long as long as 18 hours a day and have a low-energy diet of eucalyptus leaves.

Where are koalas in the food chain?
The term "kangaroo" covers over 60 species of macropods, so it varies.
Most kangaroos are herbivores but all species have both natural and introduced predators. Dingoes and wedgetail eagles are predators of kangaroos. Introduced predators such as foxes, wild dogs and feral cats are a threat to joeys. Smaller kangaroos, such as wallabies, rat-kangaroos (not kangaroo rats), potoroos, pademelons and bettongs are preyed upon by quolls and pythons.
Smaller varieties of kangaroos such as the musky-rat kangaroo are omnivores, eating fruits, seeds, fungi insect larvae and small invertebrates such as grasshoppers and beetles, so they occupy a different position in the food dhain.
Koalas are not poached for their fur. There was a time when the population of these animals dropped to dangerously low levels, due to the fur trade. this was in the late 1800s and early 1900s, but the fur trade was unfortunately quite legitimate. There was a great market in the US and the UK for koala skins. They are now protected by law.
What are some fun Koala Bear facts?
The Koala (Phascolarctos cinereus) is a marsupial mammal and is indigenous to Australia. Their closest relative is the wombat.
They live in eucalyptus trees and eat only a few types of gum leaves from which they get all nutrients and water requirements. Eucalyptus leaves are tough, toxic and low in nutrition, but the koala has developed a stomach which is capable of removing the toxins from where they are filtered out by the liver. The caecum completes the process by changing the eucalyptus leaves into digestible nutrients. The caecum is similar to the human appendix.
The koala must eat over a kilogram of leaves per day to meet its energy requirements. Eucalyptus leaves contain approximately 50% water, 18% fibre, 13% tannins, 8% fat, 5% carbohydrates, 4% protein and 2% minerals. Koalas have been seen feeding in 120 kinds of eucalypt tree including Manna Gum, Swamp Gum, Blue Gum, Forest Red Gum and Grey Gum.
- Although Koalas can sometimes be referred to "Koala Bears", they are NOT bears. They are Marsupials.
- Koalas are fully grown by their third or fourth year.
- When Koalas are born, they are about as big as a Jellybean
- Koalas also communicate with each other by making a noise like a snore and then a belch, known as a "bellow"
- Koalas are nocturnal (Sleep during the day, come out at night)
- Koalas are the only animal, other than a Possum, which can survive on a diet of eucalyptus leaves.
- Dogs and cars kill many Koalas per year.
- Koalas are protected by the law
Koalas are not vicious. For the most part, they prefer to be left alone. Some individuals may become very aggressive when touched or interfered with, but this is normal wild animal behaviour. Koalas are generally sedate creatures, and have been known to follow humans in their search for water during prolonged periods of hot weather.
When were Koalas put on the endangered species list?
Koalas have never been on the endangered species list. During the late 1800s, koalas became an export commodity for their fur, mostly for export to the USA. Due to koala numbers dwindling and public outrage, laws were enacted protecting the koala and imports were banned by the USA in the late 1920s. However, this was before conservation classifications were put into place.
The koala is not extinct, it is not even endangered. They are considered to be "Secure".
Where in the world do they cut down trees?
All over the world, trees are cut down to make paper, cardboard and to make wooden furniture. Look around you and see how much wood is around you, it all comes from trees. Usually the trees that they cut down are from forest areas.
What do koala's ears look like?
When a koala is first born, it resembles a kidney bean. Less than 2cm long, it is hairless, earless and blind.
Most of a joey's (baby koala's) development takes place in the mother's pouch. As it grows, it begins to actually look like a koala. By the time the young koala is old enough to crawl out of its mother's pouch, it is a miniature replica of its parents.
How did the Giant Koala become extinct?
The koala is not a bear; nor is it extinct.
It is a marsupial and, as of 2014, it is not even officially endangered.
During the late 1800s, koalas became an export commodity for their fur, mostly for export to the USA. Due to koala numbers dwindling and public outrage, laws were enacted protecting the koala and imports were banned by the USA in the late 1920s. By this stage, the koala had been driven to extinction in South Australia.
New colonies have been introduced in South Australia and Western Australia, and within these protected environments, the koala is thriving. Man is their biggest threat, causing loss of food source and habitat loss. Increasing urbanisation results in more koalas being killed by cars, unsupervised dogs, bushfires and even directly by cruel and irresponsible people. In particular, koalas have a range of home trees, and their territory is often split by roads through new urban developments. As a result, when koalas try to wander from one of their home range trees to another, they are hit by cars. Domestic dogs pose another major threat to koalas in suburban fringes.
Koalas have live births. They give birth like other animals but as they are marsupials their young are extremely small (bean-sized) so they grow up in the mother's pouch the same way a Kangaroo rears her young.
Are koalas prokaryotic or eukaryotic?
Rather than launch into a scientific explanation, it would be best to direct you to the following website for the answer: http://en.wikipedia.org/wiki/Eukaryote
Given that there is no such creature as a "koala bear", the answer is no country.
However, koalas, which are not bears, are common in Australia, specifically, the eastern half.
Are kangaroos found in Africa?
No. Kangaroos are native to Australia, while some tree kangaroos are also native to the island of New Guinea. While kangaroos have been introduced to some parts of the world, there have been no kangaroos introduced to any part of Africa.
Yes, non-ruminant means "having one stomach," if the koala wasn't ruminant, he would have four stomachs.
What is the koala population from 2000-2010?
The Threatened Species Scientific Committee of the Australian Government has put the koala population in the 'hundreds of thousands'. However, the Australia Koala Foundation believes a more realistic outlook is that koala numbers in the wild have dropped to below 80,000.
This depends upon the species. There are over 60 species of kangaroo, from the largest, the Red kangaroo, through many varieties of wallabies, and down to the smallest member of the kangaroo, the musky-rat kangaroo.
Because there are so many varieties, their colour varies from reddish-brown to grey, some having darker extremities (feet, nose, tail), such as the wallaroo.
Kangaroos of all species are known for their powerful legs, and all members of the kangaroo family share this characteristic of strong hind legs and short forelegs. The forelegs have no thumb. The female kangaroo has a pouch for the joey (baby). Kangaroos are well known for their jumping capabilities and use their long, powerful, muscular tails to help balance.
Where do koalas live besides Australia?
There are about 60 species of Kangaroo in Australia which are unique to Australia.
There are several species of Tree Kangaroo which are native to New Guinea and parts of Indonesia. These include the Matschie's tree kangaroo, Golden mantled tree kangaroo, Grizzled tree kangaroo, Ursine tree kangaroo, Doria's tree kangaroo, Seri's tree kangaroo, Goodfellow's tree kangaroo, Lowlands tree kangaroo, Dingiso and Tenkile.
However, some species of wallaby (a smaller member of the kangaroo family) have been introduced to other countries such as New Zealand and even Scotland.
How do koalas spend their days and nights?
Since koalas do sleep for around 22 hours a day, they spend most of their time sleeping.
Is a baby koala as big as a mouse?
No. A newborn koala joey is nowhere near the size of a mouse. In fact, even though adult koalas are very much bigger than adult mice, a koala joey when first born is about the size of a newborn baby mouse.
How many legs does a koala have?
A koala has 18 claws.
Although koalas have five digits on each of its four paws, they do not have five claws on each foot or hand. Each hand, or front foot, has five claws. However, there is no claw on the big toe of the hind foot. The second and third toes are fused together, but retain both claws, meaning that they have four claws on each hind foot.
What is another name for a koala?
The common name for a koala is "koala". The scientific name is Phascolarctos cinereus.
What would happen if humans slept like koalas?
They would fall out of the tree and never get any work done.
How many body parts does a koala have?
All body parts are used for survival in a Koala or anything else
How do koala bears adapt to savanna?
There is no such thing as a savanna koala bear. Koalas are not bears, and they do not live in the savannah.
Koalas are marsupials, and they only live in eucalyptus bushland, including bushland found within suburban areas. Savannah does not support the koala's food source.
How does the koala feed the babies?
Koalas feed by climbing certain species of eucalyptus trees which are their favoured types. They reach out to grab leaves (and occasionally, eucalyptus blossoms) with their paws, which have opposable thumbs and enable them to grip their food.
What kind of organism is a koala bear?
A koala is a marsupial, not a bear, which is a placental mammal.
