"Joey" is a general term referring to all marsupial young. Therefore, it would depend on the species of marsupial. Even within the commonly known kangaroo family, there are over sixty species, so there is no single answer.
For the animals most commonly recognised as kangaroos (e.g. Red kangaroos and Grey kangaroos), the average is about 7 months. They may continue to suckle for several months longer, but are no longer dependent on the mother.
The joey is in the mother kangaroo's pouch for about eight months (235 days), depending on the species. The young Joey continues to suckle until it is about 12 months old.
For the animals most commonly recognised as kangaroos (e.g. Red kangaroos and Grey kangaroos), the average amount of time the baby kangaroo, or joey, stays in the pouch is about 7 - 8 months.
This time is fairly consistent also with some of the smaller species of kangaroos, such as the pademelons and wallabies.
Baby kangaroos, known as joeys, do not spend even one year in the mother's pouch. The joey is in the mother kangaroo's pouch for about eight months (235 days), depending on the species. The young Joey continues to suckle until it is about 12 months old.
Very young joeys are secured in place in the pouch for several months by the simple action of the mother's teats swelling in their mouths. When the joey first enters the pouch, it immediately latches onto a teat, which then swells in the joey's mouth. This is enough to secure it in place for the first few months of its development. After this, the joey's own weight and size is enough to keep it in the pouch, especially since the top of the pouch is quite tight.
No, they do not. Female kangaroos will do nothing to harm their joey. There have been instances of kangaroos throwing their pouch open when they are being chased, but this is not the case unless the joey has reached the age where it should be independent. Young joeys are not exposed to danger in this way. Older joeys have, on occasion, been known to fall from the mother's pouch when she is being pursued, but younger joeys would not survive outside of the pouch.
No, the pouches grow later
The pouch, or marsupium, is the sac where the young joeys of most marsupials continue to grow and develop.
The female Tasmanian devil can support up to four joeys each breeding season, as she has just four teats in her pouch. However, she can give birth to anywhere between twenty and forty joeys, which are only the size of a grain of rice, and these joeys must compete for a teat in the pouch. The rest fall off and die.
No. Newborn Tasmanian devils compete for a place in the pouch as up to forty rice-sized joeys can be born at a time, but there are only four teats available. The rest of the joeys fall off and die, but because they are so tiny, they are rarely eaten.
The Northern quoll's pouch is formed by folds of skin which protect the joeys.
Kangaroos usually pouch their Joeys (baby). When a Kangaroo gives birth it puts its Joey in their pouch.
Red kangaroo joeys leave their mother's pouch at about 7-8 months. However, for another couple of months, they will still return to drink, or when they are alarmed.
Joeys are the generic name for the young of any marsupial. Marsupials are characterised by giving birth to very undeveloped young, unlike placental mammals. The joeys are blind, hairless and must stay attached to their mother's teat for several months while they continue the development that placental mammals have in the womb.Depending on the species, joeys may stay in the pouch for a few weeks or a few months. the larger marsupials keep their young in the pouch for longer.Some examples:Koala joeys stay in the pouch for 6-7 months.For the animals most commonly recognised as kangaroos (e.g. Red kangaroos and Grey kangaroos), the average amount of time the baby kangaroo, or joey, stays in the pouch is about 7 - 8 months.The antechinus may keep its joeys in the pouch for only five weeks.Sugar gliders joesy stay in the pouch for around 3 months.The joeys tend to maintain access to the pouch for another month or so after they have emerged.
No. Baby joeys that are still in the pouch feed on mothers' milk. Older joeys learn to graze with their mothers.
The Tasmanian devil is a marsupial so, like most (not all) marsupials, it has a pouch to protect its joeys while they are developing. Joeys are generally born during April, which is mid-Autumn in Australia. The young joeys are born extremely undeveloped and must compete for a teat in the pouch. Tasmanian devils can actually give birth to up to 20 joeys at a time, but having only four teats, this means most of the young die. The Tasmanian devil joeys stay in the backward-facing pouch for around four months. The pouch faces backwards so that, when the mother digs, dirt does not get into the pouch. After four months, when they are fully furred, the joeys are transferred to a den. Within another three mobs or so, they start exploring outside. By the time they are forty weeks old, during January, the joeys are fully independent.
Young koalas, or joeys, do most of their development in the mother's pouch.
