nathan917 · Answer

Marsupials essentially give birth to fetus (hind legs not yet developed, for instance), which then migrate to the placental pouch, where they attach to a teat and where they complete their growth.

Placentals mammals have an extra organ, the placenta, that provides an interface between the mother and child circulatory systems until birth.
