Jaculus jaculus can be found in central Asia, North Africa and Arabia in countries such as Sudan, Israel, and Morocco. The species is especially common in Egypt, where it gets its common name, Lesser Egyptian Jerboa. Jaculus jaculus lives in desert and semi-desert areas that can be sandy or stony. They can also be found in less numbers in rocky valleys and meadows. 
<p>Jaculus jaculus is the smallest species in the genus Jaculus. It is very small with a darkish back and lighter colored underbelly. There is also a light-colored stripe across its hip. Jerboas are a lot like a tiny kangaroo in locomotion and posture. The hind feet are incredibly large, 50 to 75 mm, and used for jumping. Each hind foot has three toes. The tail is very long, 128 to 250 mm, with a clump of hairs at the tip which is used for balance. It has moderately large eyes and ears. Females are larger than males. 
</p><p>Although lesser Egyptian jerboas lives in the desert, they do not drink, depending on the greens and insects that they eat to provide enough water and moisture. Their diet consists of roots, grass, seeds, grains, with some insects.
