A marsupial is a mammal characterized by having a pouch for carrying its young. Think of kangaroos, koalas, and opossums as prime examples. The young are born relatively undeveloped and continue their growth inside the pouch. This pouch contains mammary glands for nourishing the offspring. Marsupials are primarily found in Australia and the Americas. They represent a unique evolutionary branch of mammals. They offer a fascinating example of adaptation to different environments.
