The long-nosed potoroo (Potorous tridactylus) is a small, hopping mammal native to forests and shrubland of southeastern Australia and Tasmania.

A member of the potoroo and bettong family (Potoroidae), it lives alone and digs at night for fungi, roots, or small insects.

[4] At first glance, the long-nosed potoroo with its pointed nose and grey-brown fur looks very much like a bandicoot — that is, until it hops away with its front feet tucked into its chest, revealing its close relationship with the kangaroo family.

The long-nosed potoroo exhibits many morphological specializations such as an elongated pointed rostral region (nose), erect ears, large eyes, claws for digging, and long robust hind legs.

[6] As it is rarely seen in the wild, better indicators of its presence are the runways it makes through the undergrowth and the hollow diggings it leaves behind when feeding on underground roots and fungi.

The following is a summary of the associated species and subspecies, The long-nosed potoroo is found in a variety of microhabitats located in the Southern Highlands of New South Wales and South-Western Victoria on the Australian mainland, and in Tasmania.

[9] In Tasmania, large overlapping home ranges of 5–20 hectares (12–49 acres) have been recorded, with males typically acquiring more land than females.

[11] Fungi are the main dietary component, and are a very important resource in the potoroo's diet, with at least 50 species consumed depending on seasonal variation.

[14] The pattern of burning in areas of remaining habitat has also changed, with more severe and more frequent fires creating a sparse understorey that provides little shelter for small mammals like the potoroo.
