Southern Pig-footed Bandicoot
The Southern Pig-footed Bandicoot was a unique marsupial native to Australia, known for its distinctive pig-like feet. This small, herbivorous creature inhabited various Australian landscapes before its extinction in the mid-20th century. Its unusual anatomy and elusive nature have intrigued scientists and naturalists alike.

Classification
The Southern Pig-footed Bandicoot (Chaeropus ecaudatus) was a small marsupial, approximately the size of a kitten, with a body length of 23–26 cm and a tail measuring 10–15 cm. Its fur ranged from grizzled grey to orange-brown on the dorsal side, with lighter fawn coloring on the underside.
One of its most distinctive features was its unique limb structure: the forefeet had two functional toes with hoof-like nails, resembling those of a pig, while the hindfeet possessed an enlarged fourth toe with a heavy claw, akin to a tiny horse’s hoof; the other toes were vestigial. This unique anatomy contributed to its graceful and delicate appearance.
The species had a broad head with a long, slender snout, large pointed ears, and a long tail ending in a black tuft. Females possessed a pouch that opened backward, containing eight nipples.
Two subspecies were recognized: Chaeropus ecaudatus ecaudatus, found in southeastern Australia, and Chaeropus ecaudatus occidentalis, native to western and southwestern Australia. These subspecies were primarily distinguished by slight variations in their physical characteristics and geographical distribution.
Where Did the Southern Pig-footed Bandicoot Live?
Biogeographic Realm: Australasia
Continents: Oceania
Subcontinents: Australia and New Zealand
Countries: Australia
The Southern Pig-footed Bandicoot inhabited a wide range of habitats across Australia, including grassy woodlands, grassland plains, and arid regions with spinifex vegetation. Its distribution spanned the southern regions of Australia, from northwestern Victoria, across the Nullarbor Plain, through inland South Australia, and into the wheatbelt of Western Australia.
In the Northern Territory, it was recorded in areas such as Ryan’s Well, northeast of Charlotte Waters, and near Alice Springs. Despite this extensive range, the species was never abundant and had a sparse distribution across these regions.
What Did Southern Pig-footed Bandicoots Eat?
The Southern Pig-footed Bandicoot was primarily herbivorous, feeding on leaves, roots, and grasses. Analyses of gut contents, dentition, and gut structure of museum specimens indicate that it was the most herbivorous among peramelemorphs.
While captive specimens showed a fondness for meat, and Aboriginal reports noted consumption of grasshoppers, ants, and termites, the bulk of their diet consisted of plant material. Their unique limb structure and keen sense of smell aided in foraging for food, allowing them to efficiently locate and consume vegetation in their arid and semi-arid habitats.
What Ate Southern Pig-footed Bandicoots? – Predators & Natural Enemies
Specific details about the natural predators of the Southern Pig-footed Bandicoot are not well-documented. However, it is likely that native predators such as birds of prey, snakes, and larger marsupial carnivores preyed upon them.
Additionally, introduced species like feral cats and red foxes, brought to Australia by European settlers, became significant predators, contributing to their decline. These introduced predators, along with habitat degradation, played a crucial role in the extinction of this unique marsupial.
Behavior & Lifestyle
The Southern Pig-footed Bandicoot was a solitary and nocturnal creature, spending daylight hours in nests or burrows and emerging at night to forage. Its movement was distinctive, described as a smooth, galloping sprint, facilitated by its long, slender limbs and unique foot structure.
Depending on the habitat, it utilized various shelters to hide from predators and for sleeping. In wooded areas and grasslands, these ranged from hollow logs to nests made out of grass, while in arid, treeless country, it dug short, straight burrows with a nest at the end. Their keen sense of smell aided in locating food, and they were known to drink a considerable amount of water in captivity.
How Did Southern Pig-footed Bandicoots Reproduce?
Specific details about the reproductive habits of the Southern Pig-footed Bandicoot are scarce due to its early extinction and the limited number of observations. However, it is believed that breeding occurred between May and June, with females likely giving birth to twins, as inferred from the size of the pouch and comparison with other marsupials of similar size.
The pouch, opening backward and containing eight nipples, suggests a capacity for multiple offspring, although the typical litter size is presumed to be small. The lifespan and parental care behaviors of this species remain largely undocumented.
Are Southern Pig-footed Bandicoots Endangered? – Conservation Status & Threats
The Southern Pig-footed Bandicoot (Chaeropus ecaudatus) is classified as Extinct by the International Union for Conservation of Nature (IUCN). Once widespread in southern and western Australia, the species suffered a rapid decline following European colonization. Major threats included habitat destruction due to livestock grazing, altered fire regimes that reduced available cover, and the introduction of invasive predators such as foxes and feral cats.
The last confirmed sighting was in the 1950s, though it is believed to have disappeared earlier. Unlike some other extinct Australian marsupials, there are no conservation efforts aimed at reviving the species, as no living specimens remain. However, studying its extinction helps conservationists understand the impact of invasive species and habitat loss on Australia’s unique fauna.
