White-footed Rabbit-rat

The White-footed Rabbit-rat was a medium-sized native Australian rodent notable for its rabbit-like ears and bushy tail, resembling a small possum. It inhabited woodlands and grasslands of southeastern Australia before its extinction in the late 19th century. It was one of the first Australian mammals to become extinct following European colonization, largely due to habitat destruction and introduced predators. Its demise is emblematic of the broader collapse of Australia's small-to-medium mammal fauna after 1788.

Southeastern Australia, including Victoria, New South Wales, and South Australia

Formerly widespread across southeastern Australia, including Victoria, New South Wales, and parts of South Australia, with historical records extending to the Murray-Darling basin region.

Altitude and depth

Lowland habitats, generally below 500m elevation

Open woodlands, grassy plains, and riparian forests with dense understory vegetation. It favored areas with hollow logs and tree hollows for shelter.

Adaptations to its environment

Possessed a semi-arboreal lifestyle, using tree hollows and logs for nesting, and had strong hind limbs suited for climbing and jumping similar to rabbits. Its nocturnal habits helped avoid diurnal predators and heat during the day.

Extinct (EX) according to IUCN; the species has not been reliably recorded since the 1860s-1890s despite extensive surveys, confirming its complete disappearance.

Estimated population

Extinct — population is zero; last confirmed specimens collected in the 1850s-1860s with unconfirmed reports persisting until around 1890s.

Habitat destruction from agricultural expansion, predation by introduced red foxes and feral cats, competition with introduced rabbits, and altered fire regimes following European settlement.

No active conservation efforts exist as the species is extinct; historical museum specimens are preserved for scientific study. Its extinction has informed broader conservation strategies for surviving Australian native rodents.

Recommended actions

While recovery is impossible, recommended actions include continued predator control (foxes, cats) to protect surviving related species, habitat restoration in former range areas, and genetic studies using museum specimens to inform conservation of extant Conilurus species.

Soft grey-brown fur on the upperparts with white or pale feet (hence the name), a long bushy tail often with a white tip, and large rounded ears giving it a rabbit-like appearance.

Size

Body length approximately 18-24 cm, with a tail of similar or slightly greater length (20-25 cm)

Weight

Estimated 100-200 grams based on related Conilurus species

Distinctive features

Distinguished from other rabbit-rats by its distinctly white feet and larger, more rounded ears; its bushy tail was proportionally longer than in many related murid species.

Believed to be largely solitary or living in small family groups, based on behavior of closely related extant Conilurus species like the Brush-tailed Rabbit-rat.

When it is active

Nocturnal, sheltering in tree hollows, logs, or burrows during the day and foraging at night.

Diet

Omnivorous, likely feeding on seeds, fruits, leaves, and possibly insects, similar to related extant rabbit-rat species.

Communication

Likely used vocalizations, scent marking, and tactile communication typical of murid rodents, though specific details were never scientifically documented before extinction.

Interactions with other species

Preyed upon by native raptors and snakes historically, but introduced foxes and cats became significant novel predators that contributed to its extinction; competed with introduced European rabbits for food and habitat.

Role in its ecosystem

Likely played a role as a seed disperser and prey species within its ecosystem, contributing to nutrient cycling and food web dynamics in southeastern Australian woodlands.

Details are poorly documented, but likely gave birth to small litters (2-4 young) similar to related Conilurus species, with breeding possibly occurring in warmer months.

Raising the young

Presumed maternal care typical of murid rodents, with females nursing and protecting young in nest sites until weaning.

Maturity and lifespan

Unknown precisely, but likely reached sexual maturity within a few months and had a natural lifespan of 2-4 years, typical of similar-sized murid rodents.

Classification

Class Mammalia > Order Rodentia > Family Muridae > Genus Conilurus > Species Conilurus albipes

Scientific synonyms

Hapalotis albipes, Mus albipes

Recent studies

Recent phylogenetic research using museum specimens has helped confirm its taxonomic placement within Conilurus and its close relationship to the extant Brush-tailed Rabbit-rat (Conilurus penicillatus).

Genome and DNA

Ancient DNA has been extracted from museum specimens for phylogenetic studies, helping clarify its relationship to other Conilurus species, though no complete genome has been sequenced.

Compared with similar species

Similar in size and rabbit-like features to the Brush-tailed Rabbit-rat (Conilurus penicillatus), its closest living relative, but distinguished by white feet and a paler overall coloration.

It was one of the first mammal species to become extinct in Australia following European colonization; its rabbit-like ears and bushy tail led early settlers to nickname it the 'rabbit-rat'.

Where and how to see it

This species is extinct and cannot be observed in the wild; preserved specimens can be viewed in natural history museums such as the Museum Victoria and the Natural History Museum in London.

Risks to humans

No notable risk — species is extinct
