The animal known for carrying its young in pouches is the marsupial, most notably exemplified by kangaroos. Marsupials are a distinct group of mammals characterized by giving birth to relatively undeveloped young, which then continue their development in the mother's pouch. The pouch provides a safe environment for the young as they attach to a nipple for nourishment. Apart from kangaroos, other marsupials include koalas, opossums, and wallabies. This unique reproductive strategy allows marsupials to thrive in various habitats, mainly in Australia and nearby islands, as well as parts of the Americas.
