Description

Common wombats are sturdy and built close to the ground. When fully grown they can reach anywhere between 80 and 130cm, and between 17 and 40kg. The wombats found on Tasmania and Flinders Island are often smaller than their mainland counterparts. It is distinguished from both Hairy-nosed wombats by the fact that it has a bald nose.

Behaviour

Common wombats are a solitary, territorial species, with each wombat having an established range in which it lives and feeds. In this area, they dig a tunnel system, with tunnels ranging anywhere from 2 to 20 metres in length, along with many sidetunnels. There is usually only one entrance to the burrow, although they may create a smaller one to escape with. Often nocturnal, the common wombat does come out during the day in cooler weather, such as in early morning or late afternoon.

Diet

Common wombats are herbivorous, subsisting off grass and other plant materials. Foraging is usually done during the night.
