Jerboas can hop 10–13 cm (4–5 in) normally but if threatened by a predator the Jerboa can jump up to 3 m (10 ft). [9] Jerboas are most active at twilight (crepuscular). [10] During the heat of the day, they shelter in burrows. At night, they leave the burrows due to the cooler temperature of their environment.
The small five-toed jerboa (Scarturus elater) is a rodent of the family Dipodidae and genus Scarturus, that has five digits. [ 1 ] [ 2 ] They are hopping rodents of the rocky deserts in Asia. [ 1 ] They have been found in Afghanistan , Armenia , Azerbaijan , China , Georgia , Iran , Kazakhstan , Pakistan , Russia , Tajikistan , Turkey , and ...
The long-eared jerboa's head and body length measures 70 mm (2.8 in) to 90 mm (3.5 in) while its tail is double this size, between 150 mm (5.9 in) and 162 mm (6.4 in). [3] Like its disproportionately long tail, its hind feet are also large, helping it to jump high, measuring between 40 mm (1.6 in) and 46 mm (1.8 in). [ 3 ]
The jerboa body length ranges from 5–15 cm and has a tail ranging from 7–25 cm. [7] The "forelimbs of the jerboa serve as a pair of hands for feeding, grooming, etc." [8] Jerboas use their nose to burrow and push the dirt when looking for food. [9] The male jerboa is usually larger in size and weight in comparison to the female jerboa. [10]
The thick-tailed pygmy jerboa is a solitary nocturnal animal. It has a permanent burrow with many passages which may extend for 3 m (10 ft). The entrances are sealed with loose plugs of sand and if the jerboa is spotted in the open by a predator it attempts to bury itself in the sand.
[2] [3] They include the jerboas (family Dipodidae), jumping mice (family Zapodidae), and birch mice (family Sminthidae). [3] Different species are found in grassland , deserts , and forests . They are all capable of saltation (jumping while in a bipedal stance), a feature that is most highly evolved in the desert-dwelling jerboas.
The northern three-toed jerboa has a head-and-body length of 100 to 155 mm (4 to 6 in) and a tail of 145 to 190 mm (5.7 to 7.5 in). The weight is between 56 and 117 g (2 and 4 oz). The upper parts are ochre-brown to reddish-brown, a white band stretches from the base of the tail across the hips, and the underparts are white.
Williams's jerboa is mainly nocturnal and spends the day in a system of burrows. Emerging at night, it feeds on insects and plant material. [6] The Williams's jerboa is a common food source for the long-eared owl in Turkey. [7] Breeding takes place in spring and summer when two litters, each consisting of three to six young, are reared.
