After birth, most young marsupials, known as joeys, develop in the mother's pouch on her abdomen. Within the pouch, the teat swells in the young joey's mouth to help secure it in place. The joey remains in the pouch for up to nine months, depending on the species of marsupial.
There are some exceptions to this: the numbat, for example, has no pouch. The young remain secured in place by the swollen teat in their mouth, clinging to the mother's underbelly.

Does a placental mammal have a longer gestation period than a marsupial or is it the other way?
A placental mammal has a longer gestation period than a marsupial of similar size. This is because the baby placental mammal completes its development within the womb, unlike the marsupial joey which must complete its development in the pouch.
Why do some young animals resemble their parents?
No. Although mammals do not go through a complete metamorphosis, as amphibians do, many mammals do not look like their parents at birth. A marsupial at birth is a tiny embryo, not at all like an adult marsupial. Many mammals are born blind and hairless. Probably, the mammals that most resemble their parents at birth are the hoofed mammals.
