What is some information about how kangaroos mate and give birth?

Answer 1

Kangaroos are mammals and they mate and give birth to their young just like any other mammal- the mother gives birth through the birth canal.

However kangaroo young (joeys) are born after only 31 days of gestation, and are only the size of a Lima bean. The joey climbs up the mother and into the mother's pouch, and remains sheltered there for up to 9 months. They feed on the teats in the pouch, and as they get older, they will exit the pouch and explore, returning for safety and food.

When the joey first enters the pouch, it by instinct puts its mouth on a teat which then enlarges to hold it in place and feed it.

Further information:

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. Unlike most species of marsupial, male kangaroos do not have a bifurcated penis. Female kangaroos can often be in a state of almost permanent pregnancy, with an embryo "suspended" until the mother's body is ready to release it - whether that be when another joey is sufficiently weaned, or feeding conditions have improved.

The gestation period lasts 31-36 days. Baby kangaroos are the size of a jellybean when they are born. They are born blind and hairless. A baby kangaroo is born from the female's uterus and then climbs up the outer fur of the female and into the upward facing pouch where it attaches itself to a nipple until it becomes stronger. The mother kangaroo licks a path to the pouch to help guide the joey. Baby kangaroos live in their mother's pouch and feed by drinking milk. The teat swells in the joey's mouth, securing it in place so it cannot be accidentally dislodged. The joey will usually stay in the pouch for about 6-9 months.

Answer 2

Mating usually takes place during the rainy season when the vegetation is green and food is abundant. The female is able to delay the attachment of the embryo to the fetus so she is able to control when she will be pregnant. The joey is born after 30 days.

Answer 3

Kangaroos do not make a nest of any sort where they have their joeys. They merely give birth out in the Bush, in a reasonably secluded place, or wherever their native habitat is, depending on the species. Tree kangaroos give birth in trees, where they are safest from predators, but these are the only kangaroos that do not give birth on the ground.

Most kangaroos have no set breeding cycle and are able to breed all year round. Because they are such prolific breeders, a kangaroo population can increase fourfold in five years if it has continuous access to plentiful food and water. However, conditions will determine how often they reproduce. Female kangaroos can often be in a state of almost permanent pregnancy, with an embryo "suspended" until the mother's body is ready to release it - whether that be when another joey is sufficiently weaned, or feeding conditions have improved.

There are over sixty species of kangaroo. Some of the smaller species do have a specific breeding season, and this is usually from Australia's Spring through to early Autumn, or September to March.
