Bandicoots are nocturnal marsupial mammals native to Australia, including Tasmania, New Guinea, and their neighboring islands. They belong to the order Peramelemorphia and are characterized by a long, pointed, V-shaped snout, large ears, and sharp claws. These claws are utilized to dig through the soil while foraging for prey. Due to the tapering shape of their snouts, they end up building characteristically conical burrows in the soil.
They are opportunistic omnivores that feed on a wide range of food, including fungi, grass seeds, fruits, insects, spiders, lizards, and mice, among others. These marsupials face predation from foxes, dingoes, quolls, tiger snakes, and owls.
Bandicoots are generally harmless and are known to play a significant role in our ecosystem as soil aerators, fungal spores, and seed-dispersing agents.
These animals are about 11 to 31 in (28 to 79 cm) in length, including a tail of about 4 to 12 in (10 to 30 cm) long. They weigh between 0.4 to 3.5 lb (0.18 to 1.6 kg).
The largest bandicoot, the greater bilby, measures about 33.5 in (85 cm) and weighs up to 5.5 lb (2.5 kg). In contrast, one of the smallest species, the Western barred bandicoot, weighs only about 220 gm.
They have stout bodies with a long, pointed, V-shaped snout or muzzle. The tapering end of their head makes them resemble elephant shrews despite being distantly related to them. They have large ears (relative to their body size), a long tail, and tiny yet sharp teeth for chewing.
The hindlimbs are longer than their forelimbs for jumping. The toes are reduced in number, with two digits on the hindlimbs fused into a single toe that has two claws, a condition known as syndactyly.
As marsupials, female bandicoots have a pouch (marsupium) containing 6 to 10 teats for carrying their young. This pouch is reversed and opens towards the back to prevent dirt from entering while digging through the soil. Male bandicoots have bifurcated penises, like most marsupial males.
Their bodies are covered by coarse fur, ranging from brown and black to golden, white, or gray in color. Two species, the Eastern and Western barred bandicoots, mostly have three thick, dark stripes on their rump.
The bandicoot derives its name from the Telugu word pandikokku, which translates to the pig-rat. It actually refers to members of the genera Bandicota and Nesokia, also known as bandicoot rats.
The are 21 species of bandicoots (all under the superfamily Perameloidea) grouped under 2 extant families (Thylacomyidae and Peramelidae) and 7 genera.
These mammals are native to Australia, including Tasmania, New Guinea, and other nearby islands. Their range also extends eastward to the Bismarck Archipelago and westward to Seram and Halmahera.
The short-nosed bandicoots are found along the Australian coastline, extending to New Guinea and Tasmania. Similarly, the long-nosed bandicoots extend along the forested regions of the east coast of Australia, ranging from north Queensland to Victoria and Tasmania.
The eastern barred bandicoot is common in Tasmania, while the western barred bandicoot, once common in mainland Australia, is currently confined to the Bernier and Dorré Islands of Western Australia.
Bandicoots are opportunistic omnivores that feed on both plant and animal matter. They generally consume grass seeds, berries, and fruits, as well as insects (and their larvae), spiders, lizards, mice, snails, and even fungi.
They are generally short-lived, surviving between 2 to 5 years in the wild.
During the breeding season, the males and the females gather to mate. They may breed up to four times a year.
The embryo stays attached to the uterus via a small chorioallantoic placenta despite these mammals being classified as non-placental. Additionally, they have a choriovitelline placenta, a characteristic shared by all marsupials.
The females of most species give birth to 2 to 6 young after a gestation period of about 11 days, the shortest among all marsupials. These young are born underdeveloped (altricial) and furless, measuring barely 1 cm. They attach to the teats of the mother and feed on her milk. After about 3 months, the young are weaned, and they venture out independently.
These marsupials are preyed upon by foxes, dogs, cats, dingoes, quolls, tiger snakes, and owls.
They have a low basal metabolic rate and a low body temperature, adaptations that enable them to thrive in hot and arid climates. Additionally, their ability to minimize water loss through evaporation and profuse panting helps them endure extreme heat.
They are an ecologically important mammalian group as they constantly aerate the soil, recycling its nutrients and increasing the rate of leaf litter decomposition. Additionally, these animals help disperse seeds of plants and fungal spores.
