The desert monitor, Varanus griseus, is a species of monitor lizards living throughout North Africa and Central and South Asia. 
Monitor lizards normally display a variety of body colouration from light brown and yellow to grey. They average about one metre in length, but can reach total body lengths of almost two meters. These lizards can also have horizontal bands on either their backs or tails, along with yellow spots across their backs. 
Their young are normally a brightly coloured orange and have distinctive bands across their backs which may be lost as they mature. Their nostrils are slits located farther back on their snouts (closer to the eyes than the nose), and their overall body size is dependent on the available food supply, the time of year, environmental climate, and reproductive state. 
Males are generally larger and more robust than females, but females have a more gentle look about them. Those differences allow males to be distinguished from females from a distance without careful inspection. Adult monitor lizards also go through periods of molting in which they shed their outer layer of skin to expand their overall body size. 
This process can take several months and happens around three times per year. 
Their skin is adapted to the desert environment where they live, and they are excellent swimmers and divers and have been known to enter the water occasionally to hunt for food. They prey on the species like mice, eggs, or fish, but it will also prey on smaller mammals, reptiles, birds, amphibians, insects, or another invertebrate.
