Species and Subspecies

Bandicoots, despite their relatively lesser-known status among marsupials, boast a wide array of species across different genera. The primary genera under which most bandicoot species fall include Perameles, Isoodon, and Macrotis.

  • Perameles: This genus includes species such as the Eastern Barred Bandicoot (Perameles gunnii) and the Western Barred Bandicoot (Perameles bougainville). They are characterized by their barred patterns and elongated snouts.
  • Isoodon: Known as the short-nosed bandicoots, species under this genus, like the Northern Brown Bandicoot (Isoodon macrourus), are generally larger and have less pronounced snouts compared to the Perameles genus.
  • Macrotis: Only two species belong to this genus: the Greater Bilby (Macrotis lagotis) and the now-extinct Lesser Bilby (Macrotis leucura). Bilbies have become symbolic in Australian culture, especially around Easter as an alternative to the Easter Bunny.

While there are more species and even more subspecies, these are some of the major players in the bandicoot world. The differences among these species often revolve around size, snout length, color patterns, and habitat preferences.



Bandicoots, in general, sport a compact, robust build. They possess a pointed snout, which is longer in some species than in others, and large upright ears, especially prominent in the bilbies. Their fur can range in color from light sandy shades to darker browns and grays, often accompanied by patterns or bars, especially in the Perameles species.

  • Body Size: Ranging from small to medium, bandicoots can be as small as 6.3 inches (16 cm) in head-body length for the Desert Bandicoot (Perameles eremiana) and as large as 22 inches (56 cm) for the Bilby.
  • Distinctive Features: Besides their pointed snout and large ears, bandicoots also have a characteristic hunched back, giving them a unique silhouette. They also have strong hind legs, adapted for rapid movements and digging.
  • Sexual Dimorphism: In many bandicoot species, males are slightly larger than females. This difference isn’t always pronounced and can vary from species to species. In general, sexual dimorphism isn’t one of the major distinguishing features for bandicoots, and both genders largely share the same color patterns and physical features.

Given the variety of habitats they occupy and the spectrum of predators they face, bandicoots’ adaptability is well-reflected in their physical appearances, ranging from the dunes of Australia’s coastlines to the dense forests of New Guinea.

Habitat and Distribution

Bandicoots predominantly inhabit the regions of Australia and New Guinea, each species having its own preferred habitat type. The Eastern Barred Bandicoot, for instance, thrives in grasslands and open forests, while the Bilby has adapted to the arid desert regions of central Australia.

The vast spectrum of habitats also spans wet and dry forests, savannas, rainforests, and coastal heaths. Bandicoots are highly adaptable, making them capable of thriving in both dense foliage and more open spaces.

Tragically, many bandicoot species have seen their natural habitats diminish due to human intervention and agriculture. This has pushed some species to adapt to living on the fringes of urban areas, such as the Southern Brown Bandicoot which can sometimes be found in urban parks and gardens.



  • General Behavior: Bandicoots are primarily nocturnal creatures, coming out under the cover of night to forage and hunt for food. Their nocturnal nature serves as a protective measure against daytime predators.
  • Social Structure: Generally, bandicoots are solitary animals, especially the males. Territories are established and maintained, often marked by scent glands located on their belly. These territories might overlap slightly, especially between males and females.
  • Communication: Vocal communication is varied among bandicoots. They can produce hisses, grunts, and chirrups, each sound signifying a different emotion or message. For instance, a mother might produce soft chirruping noises to communicate with her offspring. Apart from vocal sounds, scent marking is a significant part of bandicoot communication, especially for demarcating territories.
  • Nesting and Burrowing: An interesting behavior observed in bandicoots, especially in species like the Bilby, is their propensity to dig. They excavate intricate burrows which serve as protection against predators and the elements. These burrows are spiraled, making it challenging for predators to access them easily.
  • Foraging Patterns: Equipped with a keen sense of smell, bandicoots primarily forage on the ground, using their snouts to dig and nose around for food. Their diet ranges, and their foraging patterns reflect this diversity.

Diet and Feeding Behavior

Bandicoots are primarily omnivorous, displaying a diverse diet that varies based on their specific habitat and available resources. Their food range encompasses a mix of invertebrates such as beetles, spiders, worms, and larvae. Additionally, they consume plant material including seeds, fruits, berries, and tubers. Some species might lean more towards an insectivorous diet, while others may favor plant matter.

Foraging for food primarily happens during the night, taking advantage of their sharp sense of smell to locate meals. Their conical-shaped snout assists in digging the ground, helping them uncover insects or roots hidden beneath the surface.

While foraging, bandicoots display a methodical approach, moving forward in small hops and frequently pausing to sniff the ground. Once they sense potential food, they swiftly dig using their strong forelimbs, extracting their prey or plant-based diet from the soil.


In the wild, bandicoots face threats from a range of predators. Their small size and ground-dwelling nature make them vulnerable to many carnivorous animals. Common predators include foxes, snakes, and birds of prey such as hawks and eagles. In areas closer to human habitation, domesticated animals like cats and dogs also pose significant threats.

For juvenile bandicoots, the risk is even higher. Many fall prey to these predators before reaching adulthood. This has led to the evolution of rapid reproductive cycles in many bandicoot species to counter the high juvenile mortality rates.

It’s worth noting that introduced species, especially foxes and cats, have had a particularly detrimental effect on bandicoot populations. These non-native predators, combined with habitat destruction, have significantly contributed to the decline of various bandicoot species.


Reproduction and Life Cycle

Bandicoots have a rather unique reproductive system among marsupials. They tend to breed throughout the year, depending on the availability of resources and environmental conditions. During the mating season, males become territorial and might engage in fights with rival males for mating rights.

The gestation period of bandicoots is remarkably short, one of the shortest among marsupials, lasting just 11 to 12 days for many species. After birth, the tiny, underdeveloped young migrate to the mother’s pouch, where they continue their development, latching onto her teats. They remain in the pouch for several weeks until they are more developed and can survive outside.

Typically, a bandicoot mother can give birth to 1 to 5 offspring, known as “joeys,” per litter, depending on the species. Once the young leave the pouch, they continue to stay in a nest, getting nourishment from the mother’s milk for a few more weeks. They become independent quite rapidly, and some species can even begin to reproduce at just a few months old.

Conservation and Threats

Several species of bandicoots are facing challenges in terms of conservation. With habitat destruction, introduced predators, and other human-induced factors, many populations have seen a decline over the years. Some species such as the Giant Bandicoot are listed as ‘Endangered’ on the IUCN Red List, while others remain ‘Least Concern’ or just ‘Vulnerable’.

The major threats to bandicoots include habitat destruction due to urbanization, agriculture, and forest clearing. Introduced predators like foxes and feral cats have also played a significant role in decreasing their numbers. Additionally, in some regions, diseases and road accidents contribute to their mortality.

Conservation efforts for bandicoots include habitat restoration, breeding programs, and predator control. In certain areas, initiatives have been taken to control or eradicate invasive predators. There’s also an emphasis on public education and awareness to reduce human-induced threats. Protected areas and sanctuaries have been established to offer safe havens for these marsupials, ensuring they have a fighting chance for survival.

Fun Facts

  1. Speedy Pregnancy: Bandicoots have one of the shortest gestation periods among marsupials, with pregnancy lasting just about 11 to 12 days for many species.
  2. Built-In Pockets: Like kangaroos and koalas, bandicoots are marsupials, which means females have pouches to carry and nurse their young.
  3. Night Owl: Most bandicoot species are nocturnal and will only come out at night to search for food, making them a bit elusive.
  4. Diverse Diet: Bandicoots are omnivorous and can eat a range of foods from insects and worms to seeds and fruits. This diverse diet allows them to adapt to various environments.
  5. Solo Lifestyle: Unlike some animals that live in groups, bandicoots are primarily solitary creatures, marking and defending their own territories.
