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.

What are some causes of koala endangerment?
Bush fires, deforestation, land development (urban sprawl) - habitat loss in general is one major threat to koalas. Chlamydia is another threat. In the past, hunting was a threat, but in 1920s laws were enacted to protect koalas. Since conservation efforts begun in the 1990s, the koalas have risen significantly in numbers, and on the whole, they are considered a "secure" species.
It should be noted that koalas are notofficially endangered, and are currently not in danger of extinction. They are at risk from numerous threats, however, as listed above. In addition, as a result of urban deveopment, not only do the koalas lose their sources of shelter and food, they are subject to dog attacks and being hit by cars as suburbia extends further outwards.
Koalas are territorial, and they live in complex social communities where each member has a certain number of trees within its territory. When access to these trees is cut off by new roads, the koalas will still try to cross the road, and risk being hit. Relocation of koalas is rarely successful because their territorial and social habits are largely misunderstood.
Another significant factor is predation by introduced species such as foxes.
Can a koala keep their baby in their pouch?
Yes, but there is more to it than that.
Koala joeys remain in the pouch because they are born extremely undeveloped, and this is where they feed on milk and develop fully. Like all marsupials, koala joeys are only about the size of a bean when born - approximately 19mm in length - and completely helpless. They must latch onto a teat which swells in their mouth, securing them in place in the pouch, until they are developed enough to live on their own. They are unable to survive independently of their mothers for several months.
Do koala bears need entertainment?
Koalas are not bears.
It depends on your definition of entertainment. If you like watching a smelly little furry grey animal sitting sleeping in a tree, then they are entertaining.
Koalas are not bears although they have a similar appearance. They are marsupials and as such they are born not long after conception because marspials have no placenta or umbilical through which to handle the growing offsprings needs. The tiny koala exits the birth canal and climbs through its mothers fur and into the pouch and puts its tiny mouth around a teat until it is developed enough to leave the pouch
Not especially. If you hold them, they tend to urinate on you.
Is a koala harmful or helpful to people?
They are neither helpful nor harmful directly to humans, as they eat a lot of grass etc. farmers will class them as a nuisance as they compete with cattle and sheep for food.
If they feel threatened they can be harmful.
If you want to meet a kangaroo there are tame ones in zoos and wildlife parks, but you should stay away from wild kangaroos.
Do koala bears eat meat or plants?
They don't.
Koalas feed almost exclusively on eucalyptus leaves and flowers.
They do not, and cannot, eat bamboo, which requires different types of teeth and a different digestive system from what the koala has.
How do koalas keep warm in winter?
Because Australian winters are relatively mild in the regions where koalas are found, koalas do exactly the same as they do in summer - climb trees and feed on eucalyptus leaves.
One is bush fires which burns the koalas habitats or can kill it and another one is greenhouse emissions that makes the eucalyptus leaves inedible for the koalas to eat.
Greenhouse emissions do not render eucalyptus keaves inedible for koalas. The chief danger to the koala is habitat loss. Koalas inhabit prime land which man has decided is better used for housing developments. Not only do the koalas lose their sources of shelter and food, they are subject to dog attacks and being hit by cars as suburbia extends further outwards. A prime example of this is southeast Queensland, where koala numbers have dropped to 60% less than what they were a decade ago, entirely due to increased development - and where they now face extinction by 2020.

How long is the koala's gestation?
Koalas breed from September to February. Females breed from 2 years of age, and males from 3-4 years after they have established their own territory. Males are extremely aggressive during mating periods.
Thirty-five days after mating, the female produces one joey weighing about 0.5 grams and about 2 cm long.
Koalas have a gestation period of around 35 days - one of the longer periods for marsupials.
Why is the koala bear endangered or threatened?
The koala is not on the endangered species list. The Australian Government has only very recently moved to even classify it as "Vulnerable".
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. The koala is now completely protected, and may not be hunted or killed, or even kept as a pet.
Having said that, however, just because the species is not officially threatened does not mean that they are free from threats to their future existence.

Another significant factor is predation by introduced species such as dogs and foxes.
Koalas are also subject to the disease chlamydia, which affects the koalas' fertility, and eventually leads to their death. Currently, there is no cure for this disease. At the best of times, the koala is a slow breeder, usually producing just one joey a year.
Koalas have incisors to cut the gum leaves off the tree and molars to grind the leaves. The front teeth of a koala are small and sharp in order to nip off the eucalyptus leaves which form the main component of their diet. The back teeth are larger and specially shaped to break down the tough eucalyptus leaves further.
Few US zoos have koala. They are a rare sight to see and be glad that you do get to see them. Learn about their environment and how to protect them.
San Diego is the best place to see them. Also, Albuquerque, San Francisco, Houston, Columbia SC, Cleveland, Jacksonville, and Los Angeles. I've also seen them at Lincoln Park Zoo in Chicago but I don't think they are there any more.
What is a description of a koala?
Koalas, like other marsupials, are very small when they are born. A new born koala is about the size of a bean and looks rather like a hairless grub. It climbs into its mother's pouch and suckles and grows in there. Click the link below for more information.
What is the average lifespan of the Australian koala?
There is not much scientific research into the life span of koalas in the wild, however they have been known to reach about 15 years of age in captivity. It is thought that, as animals tend to live a few years more in captivity than in the wild, a koala in its natural habitat would live anywhere from 8 to 14 years. == ==
What type of forest do koalas live in?
Koalas are indigenous to Australia and live in tropical to temperate eucalypt forest and woodlands and can be found along the eastern and south-eastern coastal regions. They live in eucalyptus trees and are mostly nocturnal and eat certain types of eucalypt leaves exclusively.
it would not be the basset hound for sure, it would be one of the breeds in the bull dog family. My opinion is the french bulldog, it is even to lazy to reproduce and is rated 32nd best city dog in America.
Do koalas eat the leaves of the spotted gum?
Yes.
While there are hundreds of different eucalyptus species in Australia, koalas eat from only about 60 of the species, consuming about half a kilogram of eucalyptus leaves every day. Koalas will not eat all types of eucalyptus, feeding on just 14 species as their primary food source, specifically, the subgenus Symphyomyrphus. Preferred eucalyptus species vary depending on their locality, so that the species eaten by Victoria koalas will be different to those eaten by north Queensland koalas. Koalas have been known to also eat the buds, flowers and bark of these particular species, while dirt also seems to supplement mineral deficiencies. Koalas have been seen feeding in eucalypt trees such as Manna Gum, Swamp Gum, Blue Gum, Forest Red Gum and Grey Gum.
Are koalas ONLY found in Australia?
Yes. The koala is native, and endemic to, Australia alone. It is not, however, found throughout the mainland, but occurs naturally in the eastern states alone. New colonies have been introduced to the far southwest of Western Australia.
They are not found anywhere else, except in selected zoos.
What biome do koalas live in in Australia?
The koala's biome is eucalypt woodland and bushland.
Koalas are particular to Eastern Australia, and can be found along the eastern and south-eastern coastal regions. They live in cool temperate zones, right up to hot, sub-tropical zones. Koalas live in a range of habitats, as long as there are abundant eucalyptus trees of the sort they prefer. They are found on coastal islands, tall eucalypt forests, bushland and low woodlands inland.
Koalas are not found in rainforests, nor in grasslands or deserts. These biomes do not support the eucalyptus trees which koalas favour. They are also not found in Alpine or snowy regions.
Koalas move regularly between eucalyptus trees in their home range. When they do come down from the trees in which they spend most of their time, they simply walk on all four legs. Their gait is a little awkward, but it serves them well, and they can move surprisingly quickly.
What adaptations have koalas made to their environment?
Koalas have very strong claws suitable for gripping trees and climbing. Between their first and second "fingers" is a large gap, which enables them to also grip tree branches comfortably, whilst their hind legs have one toe set at a wide angle. They also have toes with thick pads which enable them to sit comfortably in a tree all day. No Australian predator wants to wait that long for a meal.
Koalas' colouring also enables them to hide from predators. Their grey colouring is very difficult to see when they are high up in a tree and the leaves cast a dappled shade over them. They are effectively camouflaged.
