Marsupial Marsupial babies are born very tiny and undeveloped. Straight after birth the babies attach themselves to their mother's nipples. The babies stay attached until they develop more completely. The nipples of most female marsupials are in a pouch on the stomach. Not all female marsupials have a pouch.
All marsupials are mammals.
Kangaroos, koalas, quolls, and gliders are marsupials. Monotreme Monotremes are a special group of mammals which lay eggs. The only monotremes are echidnas and platypuses. Nectar Nectar is the sugary liquid produced by many flowers. Butterflies, some fruit bats, ants and gliders love to drink nectar.
