Bearded Dragon


The genus is in the subfamily Agaminae of the family Agamidae. Part of the Lizard family, their characteristics include broad, triangular heads and flattened bodies with spiny scales arranged in rows and clusters. These are found on the throat, which can be expanded when threatened, and at the back of the head. These spiny scales are used to scare off predators, yet they are not very sharp. Bearded dragons display a hand-waving gesture to show submission, and a head-bobbing display to show dominance between dragons. They have the ability to change color during rivalry challenges between males, in response to ambient temperature changes such as turning black to absorb heat, and other stimuli.

Bearded dragons originate from central Australia, where they live in the arid and subtropical woodlands, scrublands, savannas, shore areas, and into the great interior deserts. Their range extends throughout the interior of the eastern states to the eastern half of South Australia and southeastern Northern Territory. They spend most of their time in bushes and trees, and will often bask on rocks. When the climate is too hot they will often burrow underground.

Adult bearded dragons are very territorial. As they grow, they establish social hierarchies in which aggressive and appeasement displays form a normal part of their social interactions. The beard is used for both mating and aggression displays. Both sexes have a beard, but males display more frequently, especially in courtship rituals. Females will, however, display their beard as a sign of aggression also. The beard darkens, sometimes turning jet black and inflates during the display. The bearded dragon may also open its mouth and gape in addition to inflating its beard to appear more intimidating. Head bobbing is another behavior and it can be seen in both females and males; they quickly move their head up and down, often darkening and flaring their beard. They do this to show dominance over smaller males, weaker males, if a male wants to mate with a female or other animals they feel threatened by. Another behavior is arm waving, done by both males and females. Standing on 3 legs the bearded dragon with lift one of its front legs and move it in a circular motion. Arm waving functions as species recognition, and it is a sign of submission. Smaller males will often respond to larger males by arm waving. Females will also arm wave to avoid male aggression, often in response to a male's head bobbing.

In captivity,Bearded dragons, most commonly, the inland or central bearded dragon—are kept as pets. Introduced as pets to the US during the 1990s, they are a popular exotic species pet even though Australia, from the 1960s onward, has banned the sale of its wildlife to the pet trade They are a popular species among children because of their friendly and calm nature, and the relative ease of caring for them. Generally speaking, the bearded dragon is a solitary animal. Male bearded dragons are usually housed alone, as they will fight with other males and breed with females.

Quote of the Day

“Owners of dogs will have noticed that, if you provide them with food and water and shelter and affection, they will think you are god. Whereas owners of cats are compelled to realize that, if you provide them with food and water and shelter and affection, they draw the conclusion that they are gods.”
