Why do koalas live in South Australia?

Answer 1

If wombats moved to other places, they would come into contact with placental mammals, which would eat all of the food that the wombat might eat, and perhaps eat the wombat, thus making it die out.

Answer 2

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.

Answer 3

Koalas do not live in South Australia because their habitat does not exist in South Australia, with the possible exception of the south east corner near the Victorian border. Further information: Koalas were wiped out in South Australia by the 1920s, due to habitat loss, land clearing and the fact that a strong trade in koala fur existed. New colonies have been introduced into parts of the Fleurieu Peninsula, and they are succeeding to breed and increase. Another colony was introduced onto Kangaroo Island, off the SA coast, and it has bred so successfully that overpopulation has become a concern.

Answer 4

One of the principal reasons why kangaroos are suited to Australian conditions is that they are drought tolerant marsupials, able to graze on the fibrous leaves of native Australian grasses with minimal water. One of their most unusual adaptations is that a kangaroo is able to "turn off" a pregnancy mid-term and reabsorb the foetus to provide valuable nutrients and reduce the extra energy demand in times of extreme drought.

Kangaroos are uniquely adapted to life in Australia, a country that suffers frequent droughts.

• The mother kangaroo spends most of her adult life pregnant, but in drought times, she has the ability to indefinitely "freeze" the development of the young embryo until food sources are replenished.
• The mother can also produce two different types of milk to suit the needs of two different aged joeys. She might have a more mature joey that spends less time in the pouch, while a very young embryo has attached itself to a teat. Each joey has different milk requirements - which the mother is able to supply.
• Kangaroos are able to travel long distances at a high speed, expending very little energy. They are very energy-efficient, and this is linked directly to the physical action of bringing their hind legs up with each hop. Every hop literally refills the lungs.
• Kangaroos have large, strong tendons in their hind legs which act as "springs". The springing motion requires less energy than running does, so kangaroos are able to bound for longer distances than other mammals with the standard four legs can run. They have strong back legs and elongated hind feet for bounding.
• Kangaroos are strong swimmers. Many parts of Australia are subject to seasonal flooding rains, but the kangaroo's body shape does not prohibit it from swimming. In fact, kangaroos have been observed swimming to offshore islands off the southern coast. This is the only time the kangaroo's hind legs move independently of each other.
• Kangaroos are more active in the cooler hours of the early morning and the late afternoon. During the heat of the day they are more sedentary, lying around quietly and chewing their cud.
• The teeth of the kangaroo are continuously being worn down by the tough grasses they eat. Instead of continuously growing, once a kangaroo's front teeth are worn down completely, they fall out, and the back teeth move forwards to take the place of the worn front teeth. Kangaroos have four such pairs of chewing teeth.
• Kangaroos have the ability to hear very well: kangaroos can twitch their ears independently around to determine the direction of specific sounds, much as a cat does

These adaptations are the same for most species of kangaroos, including Red Kangaroos, Grey Kangaroos, wallaroos and wallabies.

Answer 5

Because they are used to Australia and the temperature and food is just right for them, it's the same for the koala.

Peace out!

Answer 6

Because they can't swim from Australia, to the western coast.

Answer 7

Kangaroos live everywhere in Australia, including all parts of Queensland except for the dense tropical rainforest. In some parts of this tropical rainforest, tree kangaroos can be found.

Answer 8

because its a native animal
