The long‑nosed potoroo (Potorous tridactylus) is a small marsupial native to south‑eastern Australia and Tasmania. It looks a little like a miniature kangaroo with a long, tapering snout and powerful digging claws. Mostly active at night, it forages in leaf litter and soft soils, leaving distinctive cone‑shaped diggings that can reveal its presence even when the animal is rarely seen.
A hallmark of the species is its strong reliance on underground‑fruiting fungi—often described as Australia’s original “truffle hunters.” By eating fungi and dispersing spores through droppings, potoroos help maintain mycorrhizal networks that support forest health and regeneration.
Taxonomy
This species is in the family Potoroidae (potoroos and bettongs) and the genus Potorous. In Australia, different subspecies or regional populations may be listed under federal or state legislation even when the species is not globally endangered.
Appearance
Long‑nosed potoroos are rabbit‑sized but more lightly built, with fur that can range from reddish‑brown to grey‑brown above and paler underneath. The snout is long and pointed, ears are upright, and eyes are relatively large. Strong foreclaws are used for digging, while the longer hind legs power a hopping gait. The tail is long and can assist when carrying nesting material. Females have a pouch for rearing a single young.
Range and habitat
The long‑nosed potoroo occurs in south‑eastern Australia (including parts of Queensland, New South Wales and Victoria) and in Tasmania, including some Bass Strait islands. It occupies moist eucalypt forests, coastal heath, shrublands, rainforest edges and damp gullies. The key requirement is dense ground cover and leaf litter for shelter and nesting, together with soils suitable for digging up fungi and other foods.
Behaviour
It is mainly nocturnal and usually solitary, though home ranges can overlap. Individuals often move along narrow runways through dense undergrowth. During colder months, brief daytime foraging has been recorded in some areas.
Diet
Diet is omnivorous but often dominated by hypogeal (underground‑fruiting) fungi, alongside roots, tubers, seeds, fruits, insects and larvae. Fungal feeding makes the species an important ecological engineer and spore disperser.
Reproduction and life history
Breeding can occur across much of the year depending on local conditions. Females typically give birth to a single joey after a short gestation, and the young develops in the pouch for several months before weaning. Lifespan in the wild is generally a few years and can reach around seven years; captive animals may live longer.
Conservation status and threats
Globally, the IUCN lists the long‑nosed potoroo as Near Threatened (NT). Within Australia, some subspecies or regional populations are listed as Vulnerable under federal and/or state legislation. Major threats include habitat loss and fragmentation, predation by introduced foxes and cats, road mortality, and inappropriate fire regimes that reduce dense understorey cover. Climate‑driven shifts in moisture and food availability may add pressure in some regions.
