How do marsupial reproduce?
Marsupials reproduce sexually. Female marsupials have two vaginas, or what are called paired lateral vaginae.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 does a kangaroo's reproductive system consist of?
Kangaroos do not have advanced placentas, and have epipubic bones. Epipubic bones are bones which project forwards from the pelvis. In the case of marsupials, these bones support the female's pouch, but there are other mammals which are not marsupials which also have epipubic bones. The excretory and reproductive systems of placental mammals and marsupials are also different.Female kangaroos, like other 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 kangaroo species, with the exception of the largest of the species (the Red Kangaroo, Western Grey and Eastern Grey) have a two-pronged penis to accommodate the females' two vaginas.
Are wallabies marsupials?
Yes. Wallabies give birth to undeveloped young, which then complete their development in the mother's pouch. Female wallabies, like all 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. 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.These characteristics make wallabies marsupials.
Do any marsupials not have bifubricated penises and two vaginas?
Yes. Large macropods such as kangaroos have a non-bifurcated penis. However some species still have bifurcated vaginae.
Do female kangaroos have two vaginas?
Female kangaroos have two vaginas and two uteruses. They also have a third canal that is used solely for birth.Female kangaroos have 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 kangaroos have two fallopian tubes and two cervixes. This is a feature of all marsupials, not just kangaroos. Wombats, koalas, possums and opossums, Tasmanian devils, quolls, wallabies - the females all have two sets of reproductive structures.Like most marsupials, male kangaroos, with the exception of the largest species, the Red, Eastern Grey and Western Grey, have a two-pronged penis to accommodate the females' two vaginas.
Why are koalas called marsupials?
Koalas are called marsupials, and not bears, because that is what they are - marsupials. They are not related to bears in any way; and bears are placental mammals, not marsupials. Like most (not all) marsupials, koalas have a pouch in which to keep their young. Most marsupials, including kangaroos, wallabies, possums, bandicoots and koalas, share this feature, but some marsupials such as the numbat have just a rudimentary flap of skin to protect the joeys. Like other marsupials, koala joeys 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 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. Female koalas, like other 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. Male koalas are like most male marsupials (except for the largest species, the Red Kangaroo, Eastern Grey and Western Grey Kangaroos), in that they have a bifurcated, or two-pronged penis, to accommodate the females' two vaginas.

What is unique about all the mammals in the Order Marsupialia?
Marsupials have pouches to carry their young. No other animal besides marsupials have pouches.Correction:It is not the pouch that makes marsupials unique. This is a common but erroneous belief. Not all marsupials have pouches, and some other creatures, such as echidnas, do carry their young in a pouch.What makes the marsupial different is the fact that the young are all born extremely undeveloped, after a short gestation period. Most species then nurture their joeys in a pouch, but the joeys of those that do not have a pouch cling to the mother's underbelly, secured by the mother's teat which has swollen in the joey's mouth.In addition, 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.
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 makes marsupials different from the other animals?
A marsupial is a mammal, but it is different to a placental mammal in several main ways.Marsupial young are born very undeveloped. Moving purely by instinct, the baby joey (the term for all marsupial young) makes its way to the mother's pouch, where the young joey latches onto a teat, remaining there to continue its growth and development.Many marsupials have the mammary glands enclosed within a protective pouch. Although a mammal with a pouch is always a marsupial (with the exception of the echidna, which develops a rudimentary pouch during breeding season), not all marsupials have pouches, for example, the numbat of Western Australia.All marsupials are mammals, but not all mammals are marsupials. Marsupials do not have advanced placentas, and have epipubic bones (with the exception of the marsupial mole). Epipubic bones are bones which project forwards from the pelvis. In the case of marsupials, these bones support the female's pouch, but there are other mammals which are not marsupials which also have epipubic bones. The excretory and reproductive systems of placental mammals and marsupials are also different.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 and one of the smallest species, the Honey Possum, have a two-pronged penis to accommodate the females' two vaginas.
Are Kangaroos are marsupials.?
Yes, kangaroos are marsupials. They are characterised by having very undeveloped young which continue their development in the mother's pouch. Like other marsupials, female kangaroos 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 kangaroos have two fallopian tubes and two cervixes.
What are the key differences in reproductive strategies of marsupials compared with that of placental mammals?
1. Marsupials give birth to undeveloped young after a shorter gestation period (depending on the size of the animal); placental mammals give birth to more fully developed young.2. Marsupials' placentas are not as advanced as placental mammals' placentas.3. Marsupials' young must attach to the nipple for many weeks to several months before they are developed enough to detach; placental mammals' young do not need to attach permanently to the nipple for any period of time.4. Most marsupials have pouches in which they carry their young; no placental mammals have pouches.5. Most male marsupials (with the exception of the largest species of angaroos) have a "bifurcated" or two-headed penis which is only used for reproduction; male placental mammals have a one-headed penis which is also used for urination.6. 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.
