Females normally lay clutches of 15-25 eggs in shallow nests dug into sandy soil. Young usually grow rapidly and gain adult size within a year. Life Cycle Inland bearded dragons live in harsh environments and are well adapted to eat whatever food is available. During lean seasons, they survive on nutrients and fat reserves stored in their large abdomens. If required, they will dig into the ground and remain dormant for long periods of time until unfavorable conditions, such as unusually hot or cold weather, improve.
Males have a much broader head than females.
Scales along the side of their head, throat and side of their bodies have evolved into rather soft spines. Coloration varies among the different races of the inland bearded dragons, from uniform tan to chocolate brown. The males' beard tends to be darker than the females. They may have a variety of chevron patterns down their backs, and different hues to the head, throat and tail. Juvenile inland bearded dragons express subservience toward larger, more aggressive inland bearded dragons by standing on three legs and waving their other limb in slow circles, bring it down and doing the same with the other leg.
