Notomys
A hopping mouse is any of about ten different Australian native mice in the genus ''Notomys''. They are rodents, not marsupials, and their ancestors are thought to have arrived from Asia about 5 million years ago. All are brown or fawn, fading to pale grey or white underneath, have very long tails and, as the common name implies, well-developed hind legs. Half of the hopping mouse species have become extinct since European colonisation. The primary cause is probably predation from introduced foxes or cats, coupled with competition for food from introduced rabbits and hoofed mammals. A hopping mouse's primary diet is seeds. An Australian hopping mouse can concentrate urine to as high as 10,000 mOsm/L (10-20 times higher than a human). This allows it to survive in the desert without drinking water.

Dusky Hopping Mouse
The dusky hopping mouse (''Notomys fuscus''), is a small rodent endemic to Australia, inhabiting desert regions characterised by sand dunes. Populations have experienced significant declines since the arrival of Europeans, and continue to be subject to threatening processes. It is currently listed as a threatened species. Taxonomy The dusky hopping mouse, or Wilkinti, is a mammal in the order Rodentia, and suborder Sciurognathi. The species is in the family Muridae and the subfamily Murinae (includes all Australian native rats and mice). The dusky hopping mouse belongs to the genus ''Notomys'', a group of desert-dwelling rodents. The species was originally described as ''Ascopharynx fuscus'' (Wood Jones 1925) from a specimen collected in South Australia. Subsequent collections were described as ''Notomys fuscus eyreius'' in 1960. Hopping mice collected in Queensland between 1957 to 1959 were described as a new species, ''Notomys filmeri,'' however, later taxonomic investigati ...

Big-eared Hopping Mouse
The big-eared hopping mouse (''Notomys macrotis'') is an extinct species of mouse, which lived in the Moore River area of south-western Australia. The big-eared hopping mouse was a small, rat-sized animal resembling a tiny kangaroo. It had large eyes and ears with a brush-tipped tail. It moved on its four legs when traveling at a slower pace, or by bounding upon its enlarged, padded, hind feet when traveling quickly. They mainly lived in sand dunes and made nests of leaves and other organic materials. The big-eared hopping-mouse was last collected in July 1843 near the Moore River, Western Australia, close to where New Norcia is now situated, and has not been seen since. The big-eared hopping mouse was among many hopping mice to be extinct, and its absence from extensive sub-fossil collections suggests it was restricted to Western Australia. Of the six taxa with ranges limited to Western Australia, five are considered threatened or vulnerable and one, the big-eared hopping mouse ...

Notomys Longicaudatus
The long-tailed hopping mouse (''Notomys longicaudatus'') is an extinct species of rodent in the family Muridae. It was found only in Australia. It is known from a handful of specimens, the last of which was collected in 1901 or possibly 1902. It is presumed to have become extinct within a few decades from then – possibly several decades in view of a skull fragment found in an owl pellet in 1977. The cause of extinction is unknown, but may be a variety of factors including predation and habitat alteration. Little is known of its biology other than that it dug burrows in stiff clay soils. It was less a pest to humans than other hopping mice, although it would eat raisins. The mouse was mainly gray in colour with small pink ears and big eyes with a long hairy pink tail about two inches longer than its own body. It was first described by John Gould on the basis of specimens sent to him from Australia. Taxonomy The specimens were obtained in 1843 by John Gilbert. Gilber ...

Notomys Mordax
The Darling Downs hopping mouse (''Notomys mordax'') is an extinct species of mammal in the family Muridae. It is known from a single skull found at Darling Downs, Queensland ) , nickname = Sunshine State , image_map = Queensland in Australia.svg , map_caption = Location of Queensland in Australia , subdivision_type = Country , subdivision_name = Australia , established_title = Before federation , establishe ..., Australia. Introduced predators such as foxes and domestic cats may have forced this species into extinction. The skull is identified as one of the '' Notomys'', the hopping mice, an Australian genus that has been subject to rapid declines in populations leading to local and species extinction. The skull is comparable to the species '' Notomys mitchellii'', still extant at southern coastal regions, although significant differences in the dentition distinguish this species. The provenance of the holotype was disputed after its description, although later aut ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Notomys Alexis
The spinifex hopping mouse (''Notomys alexis''), also known as the tarkawara or tarrkawarra, occurs throughout the central and western Australian arid zones, occupying both spinifex-covered sand flats and stabilised sand dunes, and loamy mulga and melaleuca flats. The population fluctuates greatly: in normal years it is sparsely distributed and probably confined to sandy country; after rain the population explodes and spreads to other types of habitat for a time. They are mostly seen at night, bounding across open ground on their large hind feet, with tails extended and the body almost horizontal. As semi-fossorial, burrowing surface foragers, the tiny hopping mice spend a great deal of energy not just foraging for food, but also transporting it back to their burrows. In fact, it was found that the total energy spent on transporting food in relation to energy investment on burrows far outweighed any other similar type of species (White, 2006).

Notomys Mitchellii
Mitchell's hopping mouse (''Notomys mitchellii'') also known as the pankot, is the largest extant member of the genus ''Notomys'', weighing between . ''N. mitchellii'' is a bipedal rodent with large back legs, similar to a jerboa or kangaroo rat. The species occurs throughout much of semi-arid Southern Australia, and appears to be particularly common on the Eyre Peninsula, South Australia. Typical habitat for ''N. mitchellii'' appears to be mallee shrublands on sandy dune systems. The species is currently considered to be unthreatened, but its range has been reduced through habitat disturbance and destruction associated with European settlement in Australia. Individuals are a sandy grey colour, with white chest hairs and a paler underbelly. The tail of the species is long and has the characteristic hopping mouse brush at the tip. This tail morphology is thought to aid balance when travelling at speed. Being nocturnal, ''Notomys mitchellii'' shelters during the day in typical ho ...
