The Aboriginal art symbol for a possum footprint is a straight line with four protruding digits that represent the four clawed toes on its hind foot. Its clawless fifth toe which can be turned like a thumb to grasp branches is ignored.
The possum, which is about the same size as a domestic cat, is a marsupial that lives in hollowed trees and logs. It emerges at night to eat and drink around waterholes, where it falls prey to Aboriginal hunters.
The possum is a traditional source of food for Aboriginal people in the bush.
