Bearded dragons are hierarchical creatures, and they motion with their heads and forelimbs to communicate with other bearded dragons. Bearded dragons are omnivores with stomachs that accept large amounts of food. Their diet includes spiders, small rodents, insects, spiders and lizards. Around 20 percent of their diet consists of vegetation.
Bearded dragons display their neck skins during the mating process or when feeling territorial. They also fan out their skin beards if they feel threatened. A bearded dragon has a flat body, but it becomes more prominent when the reptile feels alarmed.
Bearded dragons wave one of the forelimbs around in a slow and circular fashion to exhibit submission or to ward off aggression from larger dragons. A male that motions his head up and down displays dominant behavior.
