Description: Adults of this species can reach a total length of up to 24 inches, with the tail accounting for more than half. Some sexual dimorphism is present: males can be distinguished from females by a wider cloacal opening, a wider base of the tail, a larger head and beard, and the possession of hemipenes. Males also have more pronounced femoral pores than females (these can be seen as waxy bumps on the underside of the back legs). Bearded dragons vary widely in colour, including brown, reddish-brown, red, yellow, white and orange. They are capable of undergoing moderate changes in coloration, and scales along both sides of the throat, neck, and head form a row of narrow spines that runs down each side of the body to the tail. When feeling threatened, a bearded dragon will flatten its body against the ground, puff out its spiny throat and open its jaws to make itself appear larger. The bearded dragon is so named because of the pouch-like projection (also called the guttural pouch) on the underside of the neck and chin area which typically turns darker than the rest of the body. It also boasts spiny projections. Both of these characteristics appear similar to a human's beard. Males typically have a darker "beard" than females, and during mating season and courtship it will typically darken to near-black. The bearded dragon, like most agamid lizards, has strong legs which enable it to lift its body completely off the ground while it moves. This is done to reduce the heat taken in from the ground, as well as to increase the air flow over the belly to cool itself further.
Habitat: They are skilled climbers and often spend just as much time perching on tree limbs, fence posts, and in bushes as they do on the ground. They spend the morning and early evening sunning themselves on exposed branches or rocks, and retreat to shady areas or burrows during the hottest parts of the afternoon.
Range:P. vitticeps is native to the semiarid woodland, arid woodland, and rocky desert regions of Central Australia.
Diet:Pogona vitticeps are opportunistic omnivores. They live in areas where food may be hard to find, so bearded dragons are not finicky eaters. Their stomachs are large to accommodate large quantities of plant matter, insects, and the occasional small rodent or lizard.
Reproduction: The age of sexual maturity has not been measured, although it is estimated to be about one or two years.[14] Body size and growth rates are more important than age when determining sexual maturity in bearded dragons.[4] Males will become very aggressive towards each other and will assert their dominance by inflating their beards and through fast head bobbing. Breeding typically occurs in the early spring. Females will lay a clutch of 11–30 oblong-shaped eggs in a shallow nest dug in the sand. After being laid, the eggs are buried and are left unattended. The eggs will hatch approximately 60 to 80 days later, depending on the incubation temperature. In captivity, they can be incubated in a styrofoam fish box, but without a male lizard, the female's eggs will not be fertile. However, a female bearded dragon can retain sperm, and thus produce fertile eggs even after being separated from a male.
Courtship involves the male "head bobbing" to display dominance. If the female displays submissive behaviour, the male will use his mouth to grab the back of the female's head and the male will also wrap his front legs around the female's upper torso to keep her from moving. Copulation and insemination are quick. The gestation period averages about a month and a half.
Status: Inland bearded dragons have been used in scientific research. They are also very popular in the pet trade. In recent years, the bearded dragon has become a favorite reptile to keep and breed because of their manageable size and pleasant temperament. With their array of social behaviors and inquisitive nature, bearded dragons quickly become endearing to their keepers.
