Koalas and wombats are closely related native Australian mammals. Each is a marsupial found exclusively in Australia. Both species carry their young in pouches on their posterior sides. They have evolved fingerprints that are so similar to human fingerprints that even an electron microscope cannot distinguish between them.
Wombats' waste is characteristically cube-shaped. They are the only known mammal to do this unique behaviour. No one knows for sure, although it could be related to their dry environment and robust digestive systems. Wombats produce anywhere from 80 to 100 of their characteristic cube-shaped faeces per night.
