The Australian 50 cent piece, depicts an Emu and a Kangaroo holding the Australian coat of arms! The Emu is a flightless bird indigenous to Australia and is the second largest living bird. Kangaroos, also indigenous to Australia, are well known for hopping on their hind legs. They have long tails (used for balance) and like most marsupials, female kangaroos have a pouch called a marsupium in which the babies (joeys) finish their postnatal development.
