Comprised of 9 orders, 23 families, and around 330 species, with the exception of opossums, the majority of marsupials are found in Central and South America, Australia, and Asia. Immediately after birth the young crawl to the mother's nipples and remain attached to them while continuing their development.

Why do koalas have upside down pouches?

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.


Why doesn't the male koala have a pouch?

The male koala does not have a pouch for the simple reason that the male koala has no part in the raising of the young joey.

The only male marsupial which had a pouch was the Thylacine, now extinct. The Thylacine, or Tasmanian tiger, had a pouch to protect its reproductive parts whilst running through thick undergrowth. The pouch had no puspose in helping to raise the young.

Sugar Gliders

Is it illegal to own a sugar glider in New Jersey?

As far as I know, yes. They are. It could also depend on your city or county laws. Check out for a ton of information on them.

What is the lifespan of the ringtail possum?

The average life span of a ringtail possum is 5-7 years. If they are not taken by dogs or hit by cars, they can live a few years longer.


Why is a springbok classified a marsupial?

It isn't. A springbok is a member of the antelope family, and thus is a placental mammal, not a marsupial

Although Springboks have the scientific name Antidorcas marsupialias, this in no way indicates they are in an order of marsupials (Superorder or Supercohort Marsupialia). The scientific name of "marsupialis" comes from the Latin "marsupium", meaning "pocket", but the springbok does not have a marsupium. The name came aout because this animal has a pocket-like flap of skin extending from about halfway down the back, to the tail.

Sugar Gliders
How To

How to make a pouch for a sugar glider?

two simple directions for making a bonding pouch and then a nesting pouch,, as follows:

for a bonding pouch:for a simple pouch with no see thru window its very easy altho u do need a zipper because without one your gliders can get out if not yet tame.

decide how large you want your pouch, then measure it and add a half inch on each side for seam allowance. for example, if you want your pouch to be 5 inches across and 5 inches wide, cut all sides 5 1/2 inches.(this size generally works well)

take a 7 inch zipper and using satin stitch, make the zipper to size, cutting off the unused bottom part. take the two pieces of fabric and add the zipper to each side, with turning down the half inch of seam allowance beforehand to sew the zippers to, now you should have one solid piece of fabric with zipper in middle. turn inside out and stitch all sides,pivoting at corners, backstitch on end of stitching, i like to stitch strap to the sides after so the gliders don't chew on the little bulk of fabric from within,and u can make your own straps with either fabric or strong bias tape.for bias tape, just cut desired length, keeping in mind that you will need a little extra to stitch to pouch. next stitch in a small box shape to pouch high up on sides of each side. if using fabric for strap, cut desired length, stitch in a long tube, right sides together, turn, stitch the same way, but turning down a tiny bit so frayed ends don't show. now you have a basic bonding pouch.

for a pouch your gliders can sleep in:, just omit the strap and the zipper, make dimensions slightly bigger if more than two gliders sleep in it and attach strong straps on four different places with hook clips to attach to top bars. i wouldn't recommend just attacheding fabric straps and tying four straps without clips as smart gliders can figure out how to untie them and that could hurt your pet.

Australia Animal Life

Where does the musky rat kangaroo live?

The habitat and locality of the tiny musky rat-kangaroo is in the tropical rainforests of north Queensland, Australia. These rat-kangaroos, the smallest of all the kangaroo species, need to live in the wet tropics. They are restricted to the regions around Crater Lakes National Park, specifically around lake Barrine and Lake Eacham.


Why do koalas have a pouch?

Koalas have a pouch for the development of their joey. Koalas joeys are born very undeveloped, and they need to complete their development in the mother koala's pouch, where they can stay attached to a teat for all their nutritional needs, and where they are protected.


Which marsupial macropods have embryonic diapause?

Embryonic diapause is, in layman's terms, the ability of a female kangaroo to suspend the development of the embryo during gestation so that it is not born when conditions might compromise its survival, e.g. during drought. Almost all marsupial macropods have the unique feature of embryonic diapause, especially the larger and mid-sized species, such as the red kangaroos, and also many species of wallabies. Even Gilbert's potoroo, a smaller macropod, exhibits embryonic diapause.

The smallest member of the kangaroo family, the musky-rat kangaroo, does not appear to have embryonic diapause; nor do some of the tree kangaroos.

Endangered, Vulnerable, and Threatened Species

Why are some marsupials endangered?

There are two major threats to many marsupials, most of which live in Australia.

The first threat comes from animals which have been introduced into Australia, such as foxes, dogs and feral cats.

The second threat comes from habitat loss. Since European settlement, much native land has been razed to make way for housing, industry and agriculture.


What are marsupials characterized by?

Most marsupials are characterised by a pouch, but not all of them are. The numbat, for example, is a marsupial without a pouch.

However, all marsupials are characterised by the fact that the young are born extremely undeveloped, and must find their way to the mother's teat which then swells in the young joey's mouth, attaching it firmly in place while it continues its development - either inside a pouch, or clasping the mother's underbelly.

Female marsupials have two vaginas, or what are called paired lateral vaginae. These are for the purpose of transporting the sperm to the womb, but there is a midline pseudovaginal canal for actually giving birth. As well as two vaginas and two uteruses, female marsupials have two fallopian tubes and two cervixes. Most male marsupials, with the exception of the largest species, the Red Kangaroo, Eastern Grey and Western Grey Kangaroos, have a "bifurcated" or two-pronged penis to accommodate the females' two vaginas.


What marsupials lay eggs?

Marsupials do not lay eggs. They give birth to live (although undeveloped) young.

The platypus and the echidnaare both egg-laying mammals, or monotremes, not marsupials. They are still classified as mammals because they feed their young on mothers' milk - a characteristic unique to mammals alone.

There are just three known species of egg-laying mammals, or monotremes. They are the platypus and short-beaked echidna (Tachyglossus aculeatus) of Australia, and the long-beaked echidna (Zaglosssus bruijni) of Papua New Guinea. The echidna is sometimes called the spiny anteater, and there are several sub-species of the long-beaked echidna: the Western long-beaked echidna, Sir David's long-beaked echidna and the Eastern long-beaked echidna.

Biggest, Strongest, Fastest and Other Extremes

What is The Largest Marsupial?

Which of these is not a marsupial Vicuna Chuditch Tasmanian Devil or Spotted-Tailed Quoll?

The chuditch (Western Quoll), Spotted-Tailed Quoll and the Tasmanian Devil are all marsupials, found in Australia. The Vicuna is also a mammal, but of the family camelidae, meaning it is a member of the camel family.


Is a gorilla a marsupial?

Australia Animal Life

How long does a male red tail phascogale live?

Male red tailed phascogales rarely live after their first mating: they often die from stress related reasons afterwards. Thus, the average life span for males is just under a year. Females can live for four years.

Cats (Felines)

Is a cat a marsupial?

No, a cat does not have a pouch, and its young are born fully developed. It is a placental mammal.

Bobcats (animal)

Are bobcats marsupials?

No. Bobcats are not marsupials, which are pouched mammals. Bobcats are placental mammals.


What are marsupials?

Marsupials are mammals and, like all mammals, they are warmblooded vertebrates, which breathe using lungs (rather than gills), and are covered with skin, fur or hair. Mammals, including marsupials, suckle their young on mothers' milk.

Marsupials are mammals with pouches in which they rear their young. Marsupial young are characterised by being extremely small and undeveloped at birth. At birth, they take a long, arduous journey from the birth canal, driven purely by instinct, grabbing hold of the mother marsupial's fur which she has cleaned and made easier to traverse with saliva, to reach the pouch. Upon reaching the pouch, they latch onto a teat which swells in their mouth to prevent them from being accidentally dislodged during the mother's movements. There they stay for months, to complete their development.

Not all marsupials have pouches, e.g. the numbat has a mere flap of skin, but in animals where the pouch is absent, the young are still born undeveloped, and they cling by instinct to the underside of their mother's belly, still firmly attached to teats which swell in their mouths.

Female marsupials have two vaginas, or what are called paired lateral vaginae. These are for the purpose of transporting the sperm to the womb, but there is a midline pseudovaginal canal for actually giving birth. As well as two vaginas and two uteruses, female marsupials have two fallopian tubes and two cervixes. Most male marsupials, with the exception of the largest species, the Red Kangaroo, Eastern Grey and Western Grey Kangaroos, have a "bifurcated" or two-pronged penis to accommodate the females' two vaginas.

Members of the marsupial family include (among others):

  • kangaroo

Where can marsupials be found besides Australia?

About 98% of marsupials are found in Australia.

The remainder of marsupial species are found in New Guinea, some islands of Indonesia, and many more are found in Central and South America. There is also one species of marsupial, the Opossum, in North America. Brushtail Possums and wallabies have also been introduced to New Zealand, but they are not native to the islands.
