What is "jaculus"

The jaculus (or iaculus, pl. jaculi, meaning "thrown" in Latin) is a small mythical serpent or dragon. It can be shown with wings and sometimes has front legs. It is also sometimes known as the javelin snake.

The genus Jaculus is a member of the Dipodinae subfamily of dipodoid rodents ( jerboas). Jaculus species are distributed in desert and semi-arid regions across northern Africa, the Sahara, the Horn of Africa, Arabia, the Middle East, and Central Asia.

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).
