Ningaui
''Ningaui'' is a genus of small species of the marsupial dasyurid family. Along with the planigales, they are among the smallest marsupials. Taxonomy The genus was established in 1975 to accommodate two newly described species of dasyurids, the type species ''Ningaui timealeyi'' and ''Ningaui ridei''. The author, Mike Archer, compared his specimens to those of ''Sminthopsis'' (the dunnarts), distinguishing the new taxon by the structure of the skull, the hindfoot, features of dentition and their smaller size, morphology that was presumed to be specialisations to a more arid environment. The author provided a diagnosis of two species that distinguished the populations by further details of cranial and dental characters. Archer notes the tentative alliance of the species to the genus ''Planigale'' by W. D. L. Ride in 1970, and provided a new definition of that genus to separate the new taxa. The three species of the genus are: * Wongai ningaui, ''Ningaui ridei'' * Pilbara ning ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Southern Ningaui
The southern ningaui (''Ningaui yvonneae'') is a tiny marsupial carnivore belonging to the Dasyuridae family. Similar in appearance to ''Ningaui ridei'', found throughout central Australia, this species occurs in spinifex on semi-arid sandplains across the southern coast of the continent. The fur is a tawny or greyish olive colour, light grey below, and distinguished by shades of cinnamon. The southern ningaui prefers smaller prey, including insects and spiders, but capable of killing and consuming larger animals such as cockroaches and skinks. Their narrow muzzle is used with quick and fierce bites about the head to despatch their meal. The species was first described in 1983, and placed within the genus ''Ningaui''. Taxonomy The first description of the species was published in 1983 in a revision of a genus describing two species. An analysis of skull morphology revealed a third species in the widely distributed populations, which is not evident in examination of external ch ...

Wongai Ningaui
The Wongai ningaui (''Ningaui ridei'') 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, grasshopperss 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. Taxonomy ''Ningaui ridei'' and the Pilbara species, '' Ningaui timealeyi'', were two species of '' Ningaui'' described by Australian biologist Mike Archer when the genus was erected in 1975 (the southern species, ''Ningaui ...

Pilbara Ningaui
The Pilbara ningaui (''Ningaui timealeyi''), sometimes known as Ealey's ningaui, is a tiny species of marsupial carnivore found in Australia. Taxonomy The species was described by Mike Archer in 1975, distinguishing the new taxon from other dasyurids by nominating it as the type species of a new genus. Archer provided a description for a second species of '' Ningaui'', the more widely distributed ''Ningaui ridei''. The holotype is a specimen obtained escaping a fire in spinifex country, a collection made by A. Snell in 1963 at Mount Robinson in the northwest of Australia. Other material examined included a specimen collected in 1957 by E. H. M. Ealey of Monash University, then working as a field officer for the CSIRO, his informal name, 'Tim' Ealey. is the eponym of the specific epithet. Description The Pilbara ningaui is a very small species of marsupial, in length. The fur is spiky and dishevelled in appearance, the upper parts are a mix of ginger and brown hairs, or gr ...

Dasyurid
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. Characteristics Most dasyurids are roughly the size of mice, but a few species are much larger. The smallest species is the Pilbara ningaui, which is from in length, and weighs just , while the largest, the Tasmanian devil, is long, and weighs from . The smaller dasyurids typically resemble shrews or mice in appearance, with long tails and narrow, pointed noses. The larger species bear a resemblance to such plac ...

Dasyuromorphs
Dasyuromorphia (, meaning "hairy tail" in Greek) is an order comprising most of the Australian carnivorous marsupials, including quolls, dunnarts, the numbat, the Tasmanian devil, and the thylacine. In Australia, the exceptions include the omnivorous bandicoots (order Peramelemorphia) and the marsupial moles (which eat meat but are very different and are now accorded an order of their own, Notoryctemorphia). Numerous South American species of marsupials (orders Didelphimorphia, Paucituberculata, and Microbiotheria) are also carnivorous, as were some extinct members of the order Diprotodontia, including extinct kangaroos (such as ''Ekaltadeta'' and ''Propleopus)'' and thylacoleonids, and some members of the partially extinct clade Metatheria and all members of the extinct superorder Sparassodonta. The order contains four families: one with just a single living species (the numbat), two with only extinct species (including the thylacine and ''Malleodectes''), and one, the Dasyu ...

Invertebrates
Invertebrates are a paraphyletic group of animals that neither possess nor develop a vertebral column (commonly known as a ''backbone'' or ''spine''), derived from the notochord. This is a grouping including all animals apart from the chordate subphylum Vertebrata. Familiar examples of invertebrates include arthropods, mollusks, annelids, echinoderms and cnidarians. The majority of animal species are invertebrates; one estimate puts the figure at 97%. Many invertebrate taxa have a greater number and variety of species than the entire subphylum of Vertebrata. Invertebrates vary widely in size, from 50 μm (0.002 in) rotifers to the 9–10 m (30–33 ft) colossal squid. Some so-called invertebrates, such as the Tunicata and Cephalochordata, are more closely related to vertebrates than to other invertebrates. This makes the invertebrates paraphyletic, so the term has little meaning in taxonomy. Etymology The word "invertebrate" comes from the Latin word ''vertebra'', whi ...

Marsupials Of Australia
Marsupials are any members of the mammalian infraclass Marsupialia. All extant marsupials are endemic to Australasia, Wallacea and the Americas. A distinctive characteristic common to most of these species is that the young are carried in a pouch. Marsupials include opossums, Tasmanian devils, kangaroos, koalas, wombats, wallabies, bandicoots, and the extinct thylacine. Marsupials represent the clade originating from the last common ancestor of extant metatherians, the group containing all mammals more closely related to marsupials than to placentals. They give birth to relatively undeveloped young that often reside in a pouch located on their mothers' abdomen for a certain amount of time. Close to 70% of the 334 extant species occur on the Australian continent (the mainland, Tasmania, New Guinea and nearby islands). The remaining 30% are found in the Americas—primarily in South America, thirteen in Central America, and one species, the Virginia opossum, in North America, nor ...
