Description wikipedia

The desert monitor (Varanus griseus) is a species of monitor lizard of the order Squamata found living throughout North Africa and Central and South Asia. The desert monitor is carnivorous, feeding on a wide range of vertebrates and invertebrates. Desert monitors normally display a variety of body coloration from light brown and yellow to grey. They average about 1 meter in length, but can reach total body lengths of almost 2 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. Those differences allow males to be distinguished from females. Like all lizards, they go through periods of molting in which they shed their outer layer of skin to expand their overall body size. For adults, 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.
