Marsupials and monotremes represent two unique subgroups of mammals. Marsupials, like most mammals, give birth to live young. Unlike other mammals, however, many marsupials carry their young in a pouch. Well-known marsupials include kangaroos, koalas, and possums.
Monotremes, on the other hand, do not give birth to live young; they are mammals that lay eggs! The only monotreme species alive today are the platypus, a semiaquatic duck-billed animal, and four species of echidnas, spiny creatures that look like porcupines with long noses.
