Overview
The Long-footed Potoroo (Potorous longipes) is a secretive, rabbit-sized marsupial that ranks among the rarest and most elusive mammals in Australasia. Cloaked in dense, grizzled grey-brown fur, this quiet forest floor wanderer was only recognized by modern science in 1980. Specialized as an obligate truffle hunter, the potoroo spends the night excavating underground fungi, fulfilling an indispensable ecological keystone role in sustaining healthy mycorrhizal root partnerships across Australia’s ancient eucalyptus ecosystems.
Biology and Physical Characteristics
Distinguished from its closer cousin the long-nosed potoroo by its noticeably longer hind feet (exceeding 105 mm) and a faint white tip on its long tail, Potorous longipes has evolved exceptional digging adaptations. Its stout forelimbs terminate in curved, elongated claws engineered to slice through dense leaf litter and compact subsoils. An exceptionally sensitive olfactory system allows the animal to locate buried sporocarps deep beneath the surface. It possesses a sacculated stomach specialized to ferment fibrous fungal tissues through microbial fermentation, absorbing vital lipids, carbohydrates, and amino acids.
Behavior and Ecology
Long-footed potoroos are strictly nocturnal and solitary foragers that occupy stable, loosely overlapping home ranges traversed by hidden runway tunnels tunneled beneath dense wire-grass (Tetrarrhena juncea). By consuming the subterranean fruiting bodies of dozens of native fungal species and depositing viable spores across the forest floor in fecal pellets, the potoroo acts as the primary dispersal vector for tree-nourishing mycorrhizae. Breeding occurs year-round, with females raising a single joey in a forward-opening pouch following an approximate 38-day gestation.
Conservation and Human Impact
Critically Endangered on the IUCN Red List, the species faces existential pressure from habitat fragmentation, logging, unseasonal megafires, and introduced predators like feral cats and red foxes. The 2019–2020 bushfire season severely burned core breeding habitat across East Gippsland. Recovery programs managed by state wildlife authorities employ targeted predator baiting, GPS sensor cameras, and captive breeding insurance colonies to preserve this vital forest architect.
Interesting Factoid
The Long-footed Potoroo is so devoted to mushrooms that truffles make up over 80 percent of its diet, and eucalyptus trees literally depend on the potoroo’s droppings to disperse the fungi that help their roots absorb water and nutrients.
