What is a marsoupia?

You may mean 'marsupial' - that's an animal that has a pouch in which to carry its young. Marsupial young are born quite undeveloped and must live in the pouch till they are able to survive on their own. Most marsupials live in Australia.

Further information:

Marsupials are mammals and, like all mammals, they are warmblooded vertebrates, which breathe using lungs (rather than gills), and are covered with skin, fur or hair. Mammals, including marsupials, suckle their young on mothers' milk. Marsupials belong to the mammal infraclass Marsupialia.

Marsupials are mammals with pouches in which they rear their young. Marsupial young are characterised by being extremely small and undeveloped at birth. At birth, they take a long, arduous journey from the birth canal, driven purely by instinct, grabbing hold of the mother marsupial's fur which she has cleaned and made easier to traverse with saliva, to reach the pouch. Upon reaching the pouch, they latch onto a teat which swells in their mouth to prevent them from being accidentally dislodged during the mother's movements. There they stay for months, to complete their development.

Not all marsupials have pouches, e.g. the numbat has a mere flap of skin, but in animals where the pouch is absent, the young are still born undeveloped, and they cling by instinct to the underside of their mother's belly, still firmly attached to teats which swell in their mouths.

The term "marsupium", which may also be what the question means, rerrs to the pouch which most marsupials have.
