Leiurus quinquestriatus can be found in desert and scrubland habitats ranging from North Africa through to the Middle East. Its range covers a wide sweep of territory in the Sahara, Arabian Desert, Thar Desert, and Central Asia, from Algeria and Mali in the west through to Egypt, Ethiopia, Asia Minor and the Arabian Peninsula, eastwards to Kazakhstan and western India in the northeast and ...

Desert tortoises inhabit elevations from below mean sea level in Death Valley to 1,600 m (5,300 ft) in Arizona, though they are most common from around 300 to 1,050 m (1,000 to 3,500 ft). Estimates of densities vary from less than 8/km 2 (21/sq mi) on sites in southern California to over 500/km 2 (1,300/sq mi) in the western Mojave Desert ...
