Detailed explanation-1: -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.
