The Long-nosed Potoroo (Potorous tridactylus) is a small marsupial found in the southeastern forests of Australia. It has a pointed snout, grey-brown fur, and long hind legs adapted for hopping. This nocturnal creature is known for its role as a seed disperser, aiding forest regeneration.

Potorous tridactylus, commonly known as the Long-nosed Potoroo, is native to southeastern Australia. This includes regions in New South Wales, Victoria, Tasmania, and some parts of South Australia.

The Long-nosed Potoroo typically inhabits coastal heathlands, wet and dry forests, and woodlands. These areas are characterized by dense understorey vegetation, which provides cover and food resources. The climate in these regions varies from temperate to cool temperate, with moderate rainfall supporting lush vegetation.

Potorous tridactylus plays a significant role in its ecosystem as a mycophagist, primarily feeding on fungi, which helps in the dispersal of fungal spores. This is crucial for nutrient cycling and maintaining the health of forest ecosystems. The species is adapted to a life of foraging on the forest floor, often in areas with dense ground cover for protection against predators.
