The tail of a jerboa can be longer than its head and body, and a white cluster of hair is commonly seen at the end of the tail. Jerboas use their tails to balance when hopping, and as a prop when sitting upright. Jerboa fur is fine, and usually the colour of sand. This colour usually matches the jerboa habitat (an example of cryptic colouration).
The male jerboa is usually larger in size and weight in comparison to the female jerboa. [10] The pelt of the jerboa is either silky or velvety in texture and light in color, [9] the coloration helps camouflage into surroundings to avoid predators. All members of the genus have five toes.
The lesser Egyptian jerboa is a strictly nocturnal species, feeding on seeds, insects, succulent parts of desert grasses, and fungi (desert truffles Terfezia species [2]), which it detects using its acute sense of smell. Amazingly, it does not need to drink in order to survive the arid desert conditions, relying on its food to provide it with ...
Collectively, the species within the genus may be commonly referred to as "desert jerboas", although this more particularly applied to the lesser Egyptian jerboa (Jaculus jaculus). [ 1 ] Species
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 one digit less than other jerboas in the subfamily Allactaginae, but one more hind digit than other jerboas. The extra digit is smaller in size and nonfunctional ...
The long-eared jerboa (Euchoreutes naso) [2] 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 .
The forelimbs of the jerboa serve as a pair of hands for feeding, grooming, etc. [6] The male jerboa is usually larger in size and weight in comparison to the female jerboa. [5] The pelt of the jerboa is either silky or velvety in texture and light in color, [7] the coloration helps camouflage into surroundings to avoid predators. "Its ...
Hotson's jerboa is a nocturnal, solitary rodent and digs long tunnels in hard ground in which to live. The tunnels are of three types; temporary short burrows with several entrances and several tunnels and a single chamber; breeding burrows with more and longer tunnels, more numerous entrances and a nest chamber at least 30 cm (12 in) below ground level; winter burrows with a single long ...
