Marsupials have an extremely short gestation period, and the joey is 'born' basically in a fetal state. The blind, furless, miniature newborn, the size of a jelly bean, crawls across its mother's fur to make its way into the pouch, where it latches onto a teat for food. It will not re-emerge for several months, during which time it develops fully. After this period, the joey begins to spend increasing lengths of time out of the pouch, grazing and learning survival skills. However, it returns to the pouch to sleep, and if danger threatens it will seek refuge in its mother's pouch for safety.Joeys are not baby wallabies.

Marsupials are probably the forerunners of placental mammals, and they were widespread throughout the world in the early days of mammals.
There are marsupials that are catlike, doglike, mouselike, and eaters of flesh, plants, or insects, as well as some that graze, hunt, burrow, climb trees, and even glide.
