Potoroo (genus Potorous)
Small, rabbit-sized marsupials of the genus Potorous native to Australia; nocturnal diggers that feed largely on fungi and tubers. Several species exist, some critically endangered, with important ecological roles.
Overview
Potoroos are small marsupials belonging to the genus Potorous in the family Potoroidae. Often called rat‑kangaroos or long‑nosed potoroos, they resemble a cross between a rabbit and a tiny kangaroo: compact bodies with long hind limbs built for hopping, a pointed snout, and a small pouch for rearing young. They are native to Australia and occupy a variety of forest, heath and scrub habitats.

Potoroos are generally rabbit‑sized and have soft fur that ranges from greyish to brown. They possess elongated hind legs and a long tail that aids balance while moving. Their forepaws are adapted for digging: strong claws and sensitive snouts help them locate underground fungi, tubers and invertebrates. Unlike larger macropods, potoroos are solitary or live in small family groups.
Ecology and diet
These animals are primarily nocturnal foragers. A large portion of their diet is subterranean fungi (truffles), as well as roots, tubers, seeds and small invertebrates. By eating fungi and dispersing spores in their droppings, potoroos perform an important role in maintaining soil health and facilitating symbiotic relationships between mycorrhizal fungi and plants, especially eucalypts.
Distribution, habitat and behavior
Potoroos historically occurred across southern and eastern Australia, including Tasmania. Different species prefer dense understorey, heathland or wet forest where shelter and food are abundant. They nest in hollow logs, grass nests or shallow burrows and are largely secretive, using scent marking and quiet movement to avoid predators.
Conservation and human impact
Several potoroo species have declined since European settlement because of habitat loss, altered fire regimes and introduced predators such as foxes and feral cats. One species, Gilbert's potoroo, is famous for having been thought extinct until its rediscovery and is now the focus of intensive conservation, captive breeding and translocation efforts. Conservation actions for potoroos typically combine habitat protection, feral predator control and ecological restoration.
Taxonomy and notable facts
The genus Potorous contains a handful of extant species and a few that are extinct or poorly known from historical records. Potoroos are closely related to other small macropods such as bettongs and play outsized ecological roles given their size. Their reliance on fungal foods links them directly to the health of Australian forest ecosystems, making them indicators of intact understorey and soil communities.
