The Dasyuridae are a family of marsupials native to Australia and New Guinea, including 71 extant species divided into 17 genera. Many are small and mouse-like or shrew-like, giving some of them the name marsupial mice or marsupial shrews, but the group also includes the cat-sized quolls, as well as the Tasmanian devil. They are found in a wide range of habitats, including grassland, underground, forests, and mountains, and some species are arboreal or semiaquatic. The Dasyuridae are often called the 'marsupial carnivores', as most members of the family are insectivores.
The long-tailed planigale, also known as Ingram's planigale or the northern planigale, is the smallest of all marsupials, and one of the smallest of all mammals. It is rarely seen but is a quite common inhabitant of the blacksoil plains, clay-soiled woodlands, and seasonally flooded grasslands of Australia's Top End.
The former subfamily Planigalinae contained the planigales and the ningauis: very small marsupial carnivores native to Australia which are, like the quolls, antechinuses, dibblers, Tasmanian devil, and many others, part of the biological order Dasyuromorphia: the carnivorous marsupials. The subfamily is now contained in the Sminthopsinae subfamily, and the two genera are split between two different tribes; the planigales are by themselves in their own tribe, while the ningaui are lumped with the dunnarts and the Kultarr.
The common planigale, also known as the pygmy planigale or coastal planigale, is one of the small carnivorous marsupials known as "marsupial mice" found in Australia. There they fill a similar niche to the insectivores of other parts of the world.
The tiger quoll, also known as the spotted-tailed quoll, spotted quoll, spotted-tailed dasyure, or tiger cat, is a carnivorous marsupial of the quoll genus Dasyurus native to Australia. With males and females weighing around 3.5 and 1.8 kg, respectively, it is the world's second-largest extant carnivorous marsupial, behind the Tasmanian devil. Two subspecies are recognised; the nominate is found in wet forests of southeastern Australia and Tasmania, and a northern subspecies, D. m. gracilis, is found in a small area of northern Queensland and is endangered.
The northern quoll, also known as the northern native cat, the North Australian native cat or the satanellus is a carnivorous marsupial native to Australia.
The little red kaluta is a small, reddish-brown, shrew-like mammal native to dry grasslands of northwest Western Australia. It is active at night, feeding on insects and other small animals. The kaluta is a marsupial and is the only member of its genus, Dasykaluta. Individuals are around 10 cm (3.9 in) long and weigh from 20 to 40 g. They live for about four years in captivity. Other common names include little red antechinus, russet antechinus and spinifex antechinus.
The Wongai ningaui is a tiny carnivorous marsupial native to the arid open grasslands of inland Australia. Their diet is mainly small insects, and occasionally larger prey such as spiders, grasshoppers and cockroaches, which they forage for at the ground and in clumps of spinifex. They have long and untidy fur, grey or gingery brown with longer black hairs, small ears, a narrow muzzle, and possess a partially prehensile tail and feet that allow them to climb. The population occurs sparsely across a wide area and common in favourable habitat, especially in years of good rainfall. Ningaui ridei was first described in 1975, one of two species of a new genus discovered amongst the poorly known mammals of the western regions of Australia.
Antechinus is a genus of small dasyurid marsupial endemic to Australia. They resemble mice with the bristly fur of shrews.
The kultarr is a small insectivorous nocturnal marsupial inhabiting the arid interior of Australia. Preferred habitat includes stony deserts, shrubland, woodland, grassland and open plains. The kultarr has a range of adaptations to help cope with Australia's harsh arid environment including torpor similar to hibernation that helps conserve energy. The species has declined across its former range since European settlement due to changes in land management practices and introduced predators.
The fat-tailed dunnart is a species of mouse-like marsupial of the Dasyuridae, the family that includes the little red kaluta, quolls, and the Tasmanian devil.
The long-tailed dunnart is an Australian dunnart that, like the little long-tailed dunnart, has a tail longer than its body. It is also one of the larger dunnarts at a length from snout to tail of 260–306 mm of which head to anus is 80–96 mm and tail 180–210 mm long. Hind foot size is 18 mm, ear length of 21 mm and with a weight of 15-20 g.
The striped-faced dunnart is a small, Australian, nocturnal, "marsupial mouse," part of the family Dasyuridae. The species' distribution occurs throughout much of inland central and northern Australia, occupying a range of arid and semi-arid habitats.
The mammals of Australia have a rich fossil history, as well as a variety of extant mammalian species, dominated by the marsupials, but also including monotremes and placentals. The marsupials evolved to fill specific ecological niches, and in many cases they are physically similar to the placental mammals in Eurasia and North America that occupy similar niches, a phenomenon known as convergent evolution. For example, the top mammalian predators in Australia, the Tasmanian tiger and the marsupial lion, bore a striking resemblance to large canids such as the gray wolf and large cats respectively; gliding possums and flying squirrels have similar adaptations enabling their arboreal lifestyle; and the numbat and anteaters are both digging insectivores. Most of Australia's mammals are herbivores or omnivores.
Rory Cooper's false antechinus, also known as the tan false antechinus and the tan pseudantechinus, is a recently named species of small carnivorous marsupial which inhabits rocky outcrops in Western Australia. Nothing is known of its behaviour but it is expected that this will be similar to other members of the false antechinus genus. A study published in 2017 found no support for separation as a new species of Pseudantechinus, and the name was proposed to be synonymous with the previously described Pseudantechinus macdonnellensis.
Ningaui is a genus of small species of the marsupial dasyurid family. Along with the planigales, they are among the smallest marsupials.
The paucident planigale, also known as Giles' planigale, is a very small species of carnivorous marsupial of the family Dasyuridae.
The narrow-nosed planigale is a small Australian carnivorous marsupial of the family Dasyuridae.
The genus Planigale are small carnivorous marsupials found in Australia and New Guinea. It is the only genus in the tribe Planigalini of the subfamily Sminthopsinae. The genus has long been known to contain several cryptic species. Of the five Planigale species currently recognized, two are known species complexes.
The cracking-clay Pilbara planigale, formerly known as Planigale sp. Mt Tom Price, is a species of planigale first described in 2023. It is one of the smallest planigales, making it one of the smallest of all marsupials and mammals. The cracking-clay Pilbara planigale lives in the Pilbara region of Western Australia, where it co-occurs with the similar and also newly recognised orange-headed Pilbara planigale. Both species had historically been mistaken for either the common planigale, or long-tailed planigale ; neither of which are now known to occur in the Pilbara.
