Wallabies

Essentially, a wallaby is any macropod that isn't large enough to be considered a kangaroo and has not been given some other name. There is no fixed dividing line. In general, a wallaby is smaller and has a stockier build than a kangaroo; a wallaroo is any of a few species somewhat intermediate in size between a wallaby and a kangaroo.

Possums

Possums are small marsupials with brown or grey fur, ranging in size from the length of a finger (pygmy possums and wrist-winged gliders), to the length of a forearm (brushtails and ringtails). All possums are nocturnal and omnivorous, hiding in a nest in a hollow tree during the day and coming out during the night to forage for food. They fill much the same role in the Australian ecosystem that squirrels fill in the northern hemisphere and are broadly similar in appearance.
