Eared roundhead appears after wintering inlate March - early April. In the period of warm winters that occur in Central Asia, some individuals are already active at the end of February. In summer, the lizards of the desert (the photos offered to your attention will help to get an idea of ​​this reptile) are hidden from the hot sun in the afternoon, appearing only in the morning and evening hours. In early October, these creatures arrange themselves a winter shelter. To do this, they find inter-barchan lowlands and dig straight burrows of up to 90 cm in length, which end in small expansions in the layer of wet sand. In the summer period, young animals lurk in the burrows, and adults under bad weather, at night, or in case of danger, burrow into the sand with rapid oscillatory movements of the body. At the same time, the eared round-head seems to be pushing the sand in front of itself, which is picked up by scales on the sides and showered on its back, covering the lizard.

The lizard widely spreads and spreads the hind legs, raises the front part of the body and opens the mouth wide, while the mucous membrane and skin folds in the corners of the mouth become bright red. The roundhead at the same time makes a hissing sound, quickly twists and straightens the tail and jumps in the direction of the enemy. Lizards are very aggressive, and not only in the case of protection of the territory or in the mating season, but also at another time. This behavior is typical for individuals of different ages and sexes.
