The east bearded dragon ( Pogona barbata ), also known as ordinary bearded dragon or just a bearded lizard , is an agamid lizard found in parts of Australia's forests. This is one of a group of species known as bearded dragons. Other common names for this species include the Jew lizard and lacy lizards , the latter being a confusion between this and other dragons, the frill-laced lizard ( Chlamydosaurus kingii ). This species was originally described in 1829 by Georges Cuvier, who named it Amphibolurus barbatus.

Description
P. barbata is one of eight species recognized in the genus Pogona . The adult male can grow up to about 60 cm (24 inches) from the snout to the tip of the tail, while the female can reach 50 cm (20 inches) in overall length.
His head is large and triangular. Her throat is covered with dark gray scales, which can be raised to form an impressive "beard". Some groups of longer spiky scales are located at the back of the head, the corners of the mouth, external ear openings, and walk along both sides of the abdomen. Thorax and abdomen are relatively lean and flat dorsoventral.
Usually grayish black in color and sometimes reddish brown, yellowish brown, or dark brown. Teenagers are more pale in color than adults and have a pattern that fades as adults. As the animal matures, it develops a pale yellow, blue, or green tinge on the front of its head. If excited and at high head temperature, the pelvis and legs have a yellowish color to orange. But usually they are rather dark, from yellowish to gray and black. The inside of the mouth is generally bright yellow.
P. barbata resembles his close relative, the central bearded dragon, but is distinguished from the latter by a less powerful body and a row of thorns along the lateral edge of the body, which continues above the forearm. Maps Eastern bearded dragon
Distribution and habitat
It is most common in eastern Australia's southern Cape York Peninsula, but specimens have been collected from the Cape York, through central Australia, and even from the west coast of Australia.
Ecology and behavior
The eastern bearded dragon diurnal. They semiarboreal and perch in open places such as tree branches or logs, retreat to the lower and cooler when it is too hot. They are more aggressive than the central bearded dragon. Men are territorial and only allow women and adolescents in their area. Dominant males are usually the largest dragons and get the highest perch. Women tunnel to dry land to put the egg clutch.
When threatened, he inflated his throat and displayed his beard. If provoked further, he opens his mouth to show a bright yellow color on the lining of his mouth. In his close relative, the bearded dragon centers; the pink lining of the mouth. But the east-bearded dragon will perform this beard appearance more often than his cousin.
Gender makeup
Recent observations conclude that hot temperatures are responsible for some eagle bearded dragon lizards to change their gender structure. Some lizards change the appearance of their males into females, and have offspring, in addition to having a male ZZ chromosome, from a genetic male lizard.
Diet
Eastern bearded dragons feed on a variety of small animals, including rodents, smaller reptiles, and insects. In captivity, it also eats leafy vegetables such as clover and small flowers, fruits, and berries.
