The natural predators of koalas are: snakes, goannas, birds of prey, dingos. They are mostly nocturnal but sometimes you may see them moving around at dawn or dusk. They are not getting much nutrition from the leaves they eat, and it takes energy to digest the leaves, so they have to conserve their energy, which is why they sleep so much. They sleep about 18 hours a day, and no before you ask, they are not stoned. The size of these ranges depends on the habitat. Koalas are solitary animals who live in a network of overlapping ranges. This saves them having to climb down a tree and go looking for water. They eat about 500gms of leaves a day and they get most of their water from the leaves they eat. Then if they are a female, they tend to stay near their mums range, but if they’re male, have to go an find their own range. The joeys stay with their mums until they are about 12 months old. This process give the little koala the right bacteria in their tummies so they can digest eucalyptus leaves, which are quite toxic. When she’s ready to wean her joey the mumma koala excretes a substance called pap, which the joey eats.

It stays in her pouch, where is grows in size plus eyes, fur etc, until its about 6 months old, when you see them start to emerge out of the pouch for the first time. The gestation period is just 35 days, when the “jelly bean” comes out of its mums birth canal, climbs along her fur, enters her pouch and latches on to one of the two teats. koala with joeyįemale koalas give birth to one joey a year. The females become sexually active about 2 years old and the males about 3-4 years old. Each region where the koalas live, have different eucalyptus species, so despite then being essentially the same species, you can’t move koalas from Victoria to Queensland as they don’t recognise, their food trees. In saying that there are more than 700 species of eucalyptus in Australia, of those the koalas tend to eat about 30. Koalas live mostly on the east coast of Australia ( they have been introduced to other places such as South Australia and some islands). Source Save the koala Koala habitat Koala Phascolarctos cinereus victor – Southern or Victorian distribution – also includes Koalas in South Australia. Phascolarctos cinereus cinereus – Intermediate or New South Wales Distribution Phascolarctos cinereus adustus – Northern or Queensland distribution The koalas in the south are bigger and have thicker fur than those in the north. There is only one species of koala, however it is thought they may be as many as three subspecies, which explains the physical variations. It is thought that the koala and wombat diverged from the same ancestor in the Cenozoic era – sometime from 66 million years ago to the present day. These are the only marsupials whose pouches open downward rather than upward like a kangaroo. They are in the sub order Vombatiformes, which includes only the koala and wombat.
The koalas take this a step further and have two thumbs on each hand, which aids them when climbing. The other things the order Diprotodontia have in common (other than pouches), is that they have two large, procumbent incisors on the lower jaw (diprotodont – two teeth) they also have syndactyly (fused toes). They are in the order Diprotodontia, which also includes kangaroos, wallabies, wombats, possums, gliders. Which means they have a pouch and their young are called joeys (all marsupial babies are called joeys). Some people incorrectly call them koala bears – but they are not bears, they’re marsupials.
The koala ( Phascolarctos cinereus) only lives (naturally) in Australia. How on earth does something like that happen? I hear you ask, read on. Unfortunately due to the folly of white men, we could see the koalas extinction during our lifetimes. On this World Wildlife Day, I’ve chosen to highlight the plight of arguably one of the cutest animal on the planet- the koala.
