In severe cases mange can affect the wombat’s vision and ability to eat, making the animal weaker until it eventually dies. Today the species has a discontinued and fragmented distribution. Common Wombats are mainly nocturnal animals and as such are not often encountered by people in the wild. The Australian Museum respects and acknowledges the Gadigal people of the Eora Nation as the First Peoples and Traditional Custodians of the land and waterways on which the Museum stands. In sum, ten Woodchuck burrow sites were identified, resulting in a total of 18 burrows. In some habitats, wombats also feed on mosses, possibly as a source of water, given their low nutritional value. Then, in the 1930s, a small population was discovered in what is now Epping Forest National Park in central Queensland. When threatened, however, they can reach up to 40 km/h (25 mph) and maintain that speed for 150 metres (490 ft). Some wombat burrows can be about 20 metres long, with several entrances and chambers. Wombats are mostly solitary animals, but overlapping home ranges can occasionally result in a number of wombats using the same burrow. Wombats are amongst the world’s largest burrowing animals. Wombat Habitat. They have two rodentlike incisors that never stop growing. Eggs hatch after 3-4 days into larvae, which dig new burrows closer to the skin surface. Additionally, they spent more time scratching and drinking, and less time walking as a proportion of time spent above ground when compared with healthy individuals. Wombats are herbivores and feed up on grass, roots of shrubs and tress and fungi. A Bare-nosed wombat's front paws are quite dexterous and they can use them like hands.

Therefore, communication between two individuals is often threatening or aggressive. Come and explore what our researchers, curators and education programs have to offer! Burrow monitoring is undertaken on a regular basis (every 12 months) and provides information on the level of activity and which areas are being used by wombats. The platypus is common in waterways of eastern Australia, where it generally feeds on bottom-dwelling invertebrates but also takes an occasional frog, fish, or insect at the water’s surface. Similar behaviour is observed when the animal suffers from mange mite, and the soil is believed to help the animal alleviate some of the intense itchiness caused by the disease.
