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.

How does the koala communicate?
Yes. Koalas communicate with each other via snorts, hisses, grunts and other similar sounds. Males also communicate with other koalas via their strong scent glands. They have a scent gland on their chest which they use to rub against the base of certain trees to indicate their home range of trees.
What is the classification of the koala?
The classification of the koala is:
COMMON NAME: Koala
KINGDOM: Animalia
PHYLUM: Chordata
CLASS: Mammalia
INFRACLASS: Marsupialia
ORDER: Diprotodonta
FAMILY: Phascolarctidae
GENUS SPECIES: Phascolarctos (leather-pouched bear) cinereus (ash-color)
Not "anything", no.
Koalas live exclusively on a diet of eucalyptus leaves and sometimes blossoms.
Kangaroos are nocturnal, so they are active at night. This means that they do not stay anywhere at night, but rather move around through the grasslands or open bushland where they live, feeding and mating.
What else do koalas eat besides leaves?
Very little.
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. Within these 60 species, there are about a dozen of the "preferred" variety. 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 baby koalas born with fur?
Koalas spend all of their time out in the opwn, in eucalyptus (gum) trees. Because of this, they need fur that will insulate them against both the heat and the cold, and also against wet weather. The nature of koalas' fur ensures that the water will not soak through to their skin, and it also has the insulating effects of keeping them warm in cold weather, and blocking out the heat in hot weather.
Why is the Virginia opossum considered a generalist and the koala is considered a specialist?
The koala is considered a "specialist" because it can only survive within a very specialised environment, specifically where there are certain species of eucalyptus trees. The koala has a limited diet, feeding on the leaves of those trees alone. This is what makes it a specialist.
The Virginia opossum is considered a generalist because it is able to survive in a variety of environments. It is not limited to a single food source or a single type of environment. It feeds on a variety of fruits, insects, plants, and small vertebrates. As it can easily find food almost anywhere in its environment, this is what makes it a generalist.
Do koalas like climbing trees?
Koalas climb eucalypt trees because that is where their food is.
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.
Does the mother koala only have a pouch or does the father have one too?
Yes. The males have nothing to do with rearing of young koala joeys.
Is a koala a predator or prey or both a predator and a prey?
Neither. The Koala (Phascolarctos cinereus) is a tree dwelling, herbivorous, mostly nocturnal marsupial mammal and is indigenous to Australia. They live in eucalyptus trees and eat only a few types of gum leaves exclusively, from which they get all nutrients and water requirements.
What way does the koala's pouch face?
The female koala has an "upside down" or backward-opening pouch for two reasons.
Firstly, the koala is built for climbing trees. It spends many of its waking hours climbing up and down trees and along tree branches, and this can mean that all sort of debris such as pieces of bark, twigs and leaves could accumulate in a pouch that opened at the top. Having the opening at the bottom (and an opening that is securely held closed by a sphincter-like muscle) means this does not happen.
Secondly, it makes it easier for the young koala to feed once it gets older.
After a baby koala is about 28-30 weeks old, the mother produces a substance called pap. This substance is actually a specialised form of the mother's droppings which, having passed through her digestive system, give the joey the enzymes it needs to be able to start digesting the tough gum leaves, making an easier transition for the baby koala to start eating eucalyptus leaves. The koala joey's head just needs to emerge from the backward-opening pouch to feed on this pap.
Do koalas breathe through their nose?
Koalas do have rather large and prominent noses. The reason koalas have large noses is that they need to be able to tell the difference between the eucalyptus leaves they eat. Koalas will not eat all types of eucalyptus, feeding on just 14 species as their primary food source, specifically, the subgenus Symphyomyrphus.
The other reason they need such a finely tuned sense of smell is that eucalyptus leaves vary in their toxicity levels, and koalas need to be able to differentiate, avoiding the leaves when they're at their highest toxicity levels.
Koalas are quite territorial, although they share trees in their home range with other koalas. they still need to be able to detect scent warnings placed on trees by other koalas.
Newborn koalas already have quite a large nose for the size of the embryo. It has been theorised that they have an acute sense of smell already when first born to enable them to find their way to the mother's pouch. They are completely blind at this stage, but it is thought they use the scent of the mother's milk on the teats in the pouch to find their way.
Were koalas named after the kola tree?
The name is believed to come from the Aboriginal word "gula", which means "no drink." Koalas get their water from the leaves they eat, so they don't require fluid sustenance (although they will drink water in a drought or in extreme heat).
There are a number of different names for the koala in various aboriginal dialects. Some of the other names are cola/colah, koolah, boorabee, kaola, burrenbong and koolewong.
The first written name for the koala was "koolah", given in an article in the "Sydney Gazette", around 1803.
Generally, yes, koalas are placid and docile. Males do become territorial during the mating season, and they are more aggressive then.
What colors is a baby koala when it born?
Being born undeveloped, baby koalas are initially pink and hairless. As they begin to develop fur, they take on the colours of the adult. Koalas are usually either grey (the phascolarctos cinereus adustus subspecies and the phascolarctos cinereus victor subspecies) or greyish brown (phascolarctos cinereus cinereus).
What type of home does a koala live in?
Koalas do not build nests, dig burrows or live in tree hollows. Their home is in the branches of gum trees, or eucalyptus trees. They are specially adapted to sit comfortably in gum trees for most of the day.
Yes. Like other mammals, koalas give birth to live young, they feed their young with milk, and they are warmblooded, all defining features of Mammals.
Koalas, specifically, are an order of mammals known as marsupialia, or marsupials. They are mammals in every sense of the word, but they also have a pouch in which most of the development of the young joey occurs.
Do male koalas have 2 penises?
Just one.
The male has a "bifurcated" or two-pronged penis to accommodate the females' two vaginas.
What is the difference between a grizzly bear and a koala bear?
Size and location...
Kodiak Bears are the largest of the brown bears and they are found in alaska.
Grizzly bears are a little smaller and found in the northwestern North America (US and Canada).
Is a koala a marsupial placental or monotreme?
The numbat is a marsupial. It is a small, native termite-eating marsupial found in Western Australia.
Unlike almost all other marsupials, the numbat does not have a pouch.
In which country would you find the largest koala habitat?
