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 m Osm/L (10-20 times higher than a human). This allows it to survive in the desert without drinking water. Species * The spinifex hopping mouse (''Notomys alexis'') occurs throughout the central and western Australian arid zones, occupying both spinifex-covered sand flats and stabilised ...

Notomys Fuscus
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 and 1959 were described as a new species, ''Notomys filmeri,'' however, later taxonomic investigatio ...

Dusky Hopping Mouse
The dusky hopping mouse (''Notomys fuscus''), is a small rodent Endemism, endemic to Australia, inhabiting desert regions characterised by Dune, 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 Rodent, 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 ''Hopping mouse, 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 and 1959 were described as a new species, ''Notomys filmeri,' ...

Notomys Macrotis
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 ...

Fawn Hopping Mouse
The fawn hopping mouse (Notomys cervinus) is a medium sized rodent endemic to the Channel Country Bioregion of northeast South Australia and southwest Queensland in Australia. They inhabit open Desert pavement, gibber (stony) and clay plains of the Lake Eyre basin. While the population and distribution has been greatly reduced since European settlement, the current population shows little evidence of significant decline and is consequently listed as 'Near-threatened species, Near Threatened'. Taxonomy The first description of this species was published by John Gould from a holotype of unknown collection location from Victoria (state), Victoria. It was presented to the Zoological Society of London and published in 1853. The description was aided by several paratype specimens also from an unspecified location and donation. It was determined to be segregated by habitat from the dusky hopping mouse (Notomys fuscus) and identifiable by lacking throat pouches. Also by the males havin ...
