Marsupials are animals which carry their young inside a pouch. Most known are the Kangaroo and Wombat. Marsupials are most prevalent in the Southern Hemisphere, particularly Australia and South America. The only common marsupial known to be in the Northern Hemisphere is the opossum.
If it has a pouch, it must be a marsupial.

Wombats have just one pouch, not a "back pouch". What they do have is a backward-facing pouch, and this is useful because the wombat is a burrowing animal. When the female burrows, the dirt does not fly into the pouch where the wombat joey lies.

A marsupial is an animal that has a pouch. A kangaroo has a pouch so it is considered a marsupial. A kangaroo uses the pouch to carry their young after they give birth.
Boy animals do not give birth. The only animal that can even closely do that is the male seahorse, but it technically does not give birth. It just stores the eggs in its pouch.
