Marsupial

Koala (Phascolarctos cinereus)
The sugar glider, a marsupial, (left) and flying squirrel, a rodent, (right) are examples of convergent evolution.

Marsupials are an infraclass of mammals living primarily in Australasia and the Americas. A distinctive characteristic, common to many species, is that most of the young are carried in a pouch. Well-known marsupials include kangaroos, wallabies, the koala, possums, opossums, wombats, and the Tasmanian devil. Other marsupials include the numbat, bandicoots, bettongs, the bilby, quolls, and the quokka.
