Australian possums, or phalangers, are herbivorous marsupials which live in trees. They belong to the 4 main families:
Ringtails and large gliders
Brushtails and cuscus
Feathertail and pygmy possums
They are shy nocturnal creatures. Some are capable of gliding, but it's not considered true flight. they have a pouch, but also carry their young on their backs.
The greater glider possum,Petauroides volans, is an elusive creature which usually finds a home in the hollow if a gum tree.It is capable of gliding or volplaning from one tree to another by an extension of skin along the sides of the body and limbs, which when extended froms a sort of parachute.
Leadbeater's possum, Gymnobelideus leadbeateri, is a tiny possum which lives only in Victoria over an area of 100 square kilometers, extending from Marysville, north-east of Melbourne, to Tanjil Bren. After 1909 it was thought to be extinct but was re-discovered in 1961, again at Marysville. It is the animal emblem of Victoria.
