Dipodidae
Jerboas (from ar, جربوع ') are hopping desert rodents found throughout North Africa and Asia, and are members of the family Dipodidae. They tend to live in hot deserts. When chased, jerboas can run at up to . Some species are preyed on by little owls (''Athene noctua'') in central Asia. Most species of jerboas have excellent hearing that they use to avoid becoming the prey of nocturnal predators. The typical lifespan of a jerboa is around 6 years. Taxonomy Jerboas, as previously defined, were thought to be paraphyletic, with the jumping mice (Zapodidae) and birch mice (Sminthidae) also classified in the family Dipodidae. However, phylogenetic analysis split all three as distinct families, leaving just the jerboas in Dipodidae and revealing them to be a monophyletic group. Anatomy and body features Jerboas look somewhat like miniature kangaroos, and have some external similarities. Both have long hind legs, short forelegs, and long tails. Jerboas move around in a similar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Allactaga Tetradactyla
The four-toed jerboa (''Allactaga tetradactyla'') is a rodent of the family Dipodidae and genus ''Allactaga'' that has four digits. It is the sole species in the subgenus ''Scarturus''. Four-toed jerboas are native to Egypt and Libya. They live in coastal salt marshes and dry deserts. Physical appearance Similar to the other jerboas in the genus ''Allactaga'', the four-toed jerboa are small hopping rodents with large ears and a long tail, with a black band near the white, feathery tip. The tail assists and serves as support when the jerboa is standing upright. They have long hind feet and short forelegs. The pelt of the four-toed jerboa is velvety in texture and the upper-parts are speckled black and orange, the rump orange, and the sides gray. The four-toed jerboa hind-limbs have an extra digit compared to other jerboas in the genus ''Allactaga''. The extra digit is smaller in size and nonfunctional compared to the other three digits.

Euchoreutinae
The long-eared jerboa (''Euchoreutes naso'') is a nocturnal mouse-like rodent with a long tail, long hind legs for jumping, and exceptionally large ears. It is distinct enough that authorities consider it to be the only member of both its genus, ''Euchoreutes'', and subfamily, Euchoreutinae. Long-eared jerboas are found in the Palearctic ecozone. The specific palearctic ecozone areas they are found in are southernmost Mongolia to the Takla-Makan Desert, Mengxin, Aerijin Mountain, and Qing-Zang Plateau regions of north western China. Long-eared jerboas in most cases are nocturnal, The long-eared jerboa's fur according to the book ''100 animals to see before they die'' "is reddish yellow to pale russet with white underparts." Very little is known about the species. Description The long-eared jerboa's head and body length measures to while its tail is double this size, between and . Like its disproportionately long tail, its hind feet are also large, helping it to jump high, me ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Zapodidae
Zapodidae, the jumping mice, is a family of mouse-like rodents in North America and China. Although mouse-like in general appearance, these rodents are distinguished by their elongated hind limbs, and, typically, by the presence of four pairs of cheek-teeth in each jaw. There are five toes to all the feet, but the first in the fore-feet is rudimentary, and furnished with a flat nail. The tail makes up about 60% of its body length and is used to gain balance while jumping. The cheeks have pouches. The Sichuan jumping "yeti" mouse ('' Eozapus setchuanus'') from China can be identified by the ‘Y’ marking on its belly. Jumping mice live in wooded areas, grassy fields and alpine meadows. When disturbed, they start, in enormous bounds of eight or ten feet in length, which soon diminish to three or four, and in leaping the feet scarcely seem to touch the ground. They are nocturnal and generally live alone. The nest is placed in clefts of rocks, among timber, or in hollow trees, and ...

Sminthidae
Sminthidae is a family of mouse-like jumping rodents. They are represented by only one extant genus, ''Sicista'', represented by 19 species found throughout most of Eurasia, from central Europe east to Siberia, and south to southern China. However, they were much more diverse and had a much wider range in prehistoric times, having multiple genera and being found not only in Eurasia but also throughout North America, where they existed up to the early Pleistocene. They have a well-attested fossil record which dates as far back as the early Oligocene. They were formerly classified as the subfamily Sicistinae in the family Dipodidae alongside the jerboas and jumping mice, but phylogenetic evidence supports all three of these belonging to distinct families, thus leaving only the jerboas in Dipodidae.

Rodent
Rodents (from Latin , 'to gnaw') are mammals of the order Rodentia (), which are characterized by a single pair of continuously growing incisors in each of the upper and lower jaws. About 40% of all mammal species are rodents. They are native to all major land masses except for New Zealand, Antarctica, and several oceanic islands, though they have subsequently been introduced to most of these land masses by human activity. Rodents are extremely diverse in their ecology and lifestyles and can be found in almost every terrestrial habitat, including human-made environments. Species can be arboreal, fossorial (burrowing), saltatorial/richochetal (leaping on their hind legs), or semiaquatic. However, all rodents share several morphological features, including having only a single upper and lower pair of ever-growing incisors. Well-known rodents include mice, rats, squirrels, prairie dogs, porcupines, beavers, guinea pigs, and hamsters. Rabbits, hares, and pikas, wh ...

Head and body length of and hind foot length of . The animal's skin color is light brown or dark-brown to brownish yellow on the upper side and paler on the underside, but generally brownish.
