The term 'Australian Arboreal Marsupial' refers to two animals native to Australia: the Tuan (also known as the Brush-tailed Possum) and the KOALA. The Tuan is a small, nocturnal marsupial with a long, bushy tail and a grey-brown coat. It is an arboreal species, meaning it lives in trees, and is found in forests and woodlands across Australia. The KOALA is another arboreal marsupial, but is much larger than the Tuan. It has a thick, grey fur and is well-known for its large, round ears and distinctive black nose. It is a herbivore, feeding on eucalyptus leaves, and is found in eastern and southern Australia.
