Uromastyx is a genus of African and Asian agamid lizards, the member species of which are commonly called spiny-tailed lizards, uromastyces, mastigures, or dabb lizards. Lizards in the genus Uromastyx are primarily herbivorous, but occasionally eat insects and other small animals, especially young lizards. They spend most of their waking hours basking in the sun, hiding in underground chambers at daytime, or when danger appears. They tend to establish themselves in hilly, rocky areas with good shelter and accessible vegetation.
Uromastyx inhabit a range stretching through most of North and Northeast Africa, the Middle East, ranging as far east as Iran. Species found further east are now placed in the genus Saara. Uromastyx occur at elevations from sea level to well over 900 m (3,000 ft). They are regularly eaten, and sold in produce markets, by local peoples.
