Detailed explanation-1: -Marsupial mammals give birth to young that complete their development in a pouch on the mother’s abdomen. All the native mammals of Australia are marsupials, while these types of mammals are absent or uncommon on other continents.

Detailed explanation-2: -Marsupials are born at a very immature state, and they must make their way to the marsupium, or pouch, and attach to the mother’s nipple in order to survive.

Detailed explanation-3: -Well, marsupials are the kinds of animals that can do this. They are known as pouched mammals, because the adult females have a marsupium, or pouch. Young marsupials (called joeys) do most of their early development outside of their mother’s body, in a pouch. The pouch acts as a warm, safe place where the joeys grow.

Detailed explanation-4: -An early birth removes a developing marsupial from its mother’s body much sooner than in placental mammals; thus marsupials have not developed a complex placenta to protect the embryo from its mother’s immune system.

Detailed explanation-5: -C Order Marsupialia. Marsupials-represented by the opossum, kangaroo, wombat, and bandicoot-give birth to live but very immature young after a nonplacental pregnancy.
