  Wikipedia: Hopping mouse
The Fawn Hopping Mouse (Notomys cervinus) is found on the sparsely vegetated arid gibber plains and claypans of the Lake Eyre Basin.
The Darling Downs Hopping Mouse (Notomys mordax) is almost certainly extinct and is known only from a single skull collected somewhere on the Darling Downs of south-east Queensland in the 1840s, apparently from a creature similar to Mitchell's Hopping-mouse.
It is notable that very few of the clay-living hopping mice have survived European settlement, sand dunes apparently providing a more secure refuge from competitors and predators.

The name derives from their bipedal form (they hop like tiny kangaroos) but the resemblance is purely visual: kangaroo rats and kangaroos are not related, other than in that both groups are mammals.
Despite sharing so many characteristics with jerboas and hopping mice, the three groups are not closely related to one another: the similarities are the result of convergent evolution.
Unlike the jerboas and hopping mice, but like their close relatives the pocket mice, kangaroo rats have large cheek pouches that open on either side of the mouth and extend back to the shoulders.

 Energetic cost of locomotion in Australian hopping mice
THE mode of locomotion of the hopping mouse can be compared with that of the kangaroo moving bipedally at speed.
Because the latter cannot be monitored due to technical difficulties, I have used the hopping mouse in a study of the energetics of this type of locomotion at speeds of 0.5−7 km h
The result of this pattern was that the costs of hopping in Notomys cervinus were markedly below those predicted for a quadruped.

 Dusky Hopping Mouse
The Dusky Hopping Mouse (Notomys fuscus) is an Australian native rodent specialised for the deep desert.
Like all hopping mice it has strong front teeth, a long tail, dark eyes, big ears, well-developed haunches and very long, narrow hind feet.
The reasons for the decline of the Dusky Hopping Mouse are not fully understood, but are assumed to be competition for food with introduced species, particularly cattle and rabbits, and predation by introduced cats and foxes[?].

Mice convert plants that are carbohydrates to protein.
Mice propel themselves with their powerful hind legs, and land on their front legs.
It should be noted that mice spend much of their time inside the snow pack feeding on seeds, bark and vegetation.

 Jerboa
Their ability to hop is presumed to be an adaptation to help them escape from predators, and perhaps to assist with the longer journeys a desert-living animal must make to find food.
It is interesting to note that although jerboas are not closely related to the hopping mice of Australia or the kangaroo rats of North America, all three groups have evolved a similar set of adaptations to life in the deep desert.
Found in both the sandy and stony deserts of north Africa, Arabia and Iran, this small creature aestivates (a form of hibernation) during the hottest summer months, and has the ability to leap a full metre to escape a predator.

 Heteromyidae: Kangaroo Rats & Pocket Mice
Despite their names, they are neither rats nor mice; and in spite of their mouse-like appearance, they are not closely related to any other species of North American rodent.
Kangaroo rats and pocket mice are all nocturnal, burrowing animals with external fur-lined cheek pouches for storing and transporting the seeds that are their primary food.
The pocket mice are also primarily granivorous (seed eating), most often eating mesquite beans and the seeds of grasses, creosote bushes, and weeds.

Progeny testing is required to identify the genotype of mice of this strain, as a genotyping assay is not available.
The progeny testing cost is in addition to the recovery cost and is based on the number of boxes used and the time taken to produce the mice identified as carrying the mutation.
To ensure that JAX® Mice will meet the needs of individual research projects or when requesting a strain that is new to your research, we suggest ordering and performing tests on a small number of mice to determine suitability for your particular project.

 Mice
Mice are probably the most well known rodents of all because they live almost everywhere in the world.
Some kinds of mice are the North African striped grass mouse, house mouse, African climbing mouse, common door mouse, harvest mouse, striped field mouse, Australian hopping mouse, leaf-eared mouse, African house mouse, meadow jumping mouse, grass hopping mouse, and Mexican volcano mouse.
Mice that live in the fields have these animals for enemies: kestrels, buzzards, owls, other mice, weasels, foxes, and humans.

 Nature Feature - Red Kangaroo
Kangaroos and their kin are characterised by powerful hindlimbs and long hind feet which are usually employed in a fast hopping gait.
It is possible to imagine a kangaroo-like animal that could run on its hindlegs like an emu or a frill-necked lizard but the neuromuscular coordination of most kangaroos is such that the hindlegs must move together when used in terrestrial locomotion.
No macropodid has a prehensile tail, this structure serving as a balancing counter-weight when an animal is hopping, as a prop when standing upright and as a fifth limb in slow locomotion.

The Australian hopping mouse lives in the deserts and semi-deserts of the Australian midlands.
They usually walk on all four, which results in a cute hopping movement because of the length difference between the front and hind legs.
The mice do pollute their nest, so it has to be cleaned regularly.

The Fawn Hopping Mouse (Notomys cervinus) is a rodent native to the central Australian desert.
During the day, they shelter in burrows which are simpler and shallower than those of the sand-dwelling Dusky Hopping Mouse but nevertheless up to a metre deep with between one and three entrances.
As with other hopping mice, they do not need to drink, though they can metabolise highly saline water if it is available.

These subfamilies include the Leimacomyinae (groove-toothed forest mouse), the Deomyinae (spiny mice, brush furred mice, and link rat), the Gerbillinae (gerbils, jirds, and sand rats), the Murinae (Old World rats and mice), and the Otomyinae (vlei rats, karoo rats, and whistling rats).
Some species of murids are indeed small--tiny African pygmy mice (Mus minutoides) have bodies less than 9 cm long and weigh in at under 5 grams--but some are much larger, like southern Luzon giant cloud rats (Phloeomys cumingi), which grow to over 48 cm long and weigh over 2 kg.
There are murids that are specialized for hopping, climbing, swimming, and murids that are capable of all of these modes of locomotion.
