The Eastern bearded dragon, also called Jew Lizard, Pogona barbata, is a lizard found in wooded parts of Australia.[1] It is most common in eastern Australia south of Cape York Peninsula, but specimens have been collected from Cape York, through central Australia, and even from the west coast of Australia. It is a large species of grey-black colour distinguished from its relative, the central bearded dragon, Pogona vitticeps, by its less robust body and the row of spines along the lateral edge of the body, which continues over the forearm (Cogger, 1992). It tends to be more cryptic in its behaviour than the Central bearded dragon and performs its bearded display more often. It has an adult snout-tail length of about 24 inches (60 cm). When threatened, in addition to its beard display, it gapes – turning its mouth a very pale yellow colour. They eat small lizards and snakes, flowers, insects, fruits, and berries.

[edit] Physical description
The eastern bearded dragon resembles its close relative the smaller central bearded dragon. It is usually grey-black in skin colour and is sometimes reddish-brown, yellowish-brown, or dark brown. Juveniles are paler in colour than the adults and have patterns that fade as they mature. As it matures it develops a hard to notice pale yellow, blue, or green tinge on the forepart of its head. The adult males can grow up to about 24 inches (60 cm), and females up to 20 inches (50 cm). The adult males have a dark grey to black "beard". Eastern bearded dragons' status in the wild is very rare.
[edit] Behavior
Eastern Bearded Dragons are diurnal. They are semi-arboreal and perch on semi-high places retreating to lower and darker places when too hot. The eastern bearded dragon is also known to do the arm wave as a sign of submission or just for general communication. Their beard is displayed when agitated or threatened, or for territorial and mating displays. When agitated they also gape and hiss. The eastern bearded dragon is more aggressive than the central bearded dragon, demands more space and is less docile. The males are very territorial and only have submissive females and juveniles in their territory. Dominant males are usually the biggest dragons and get the highest perch.Eastern bearded dragons status in the wild is very rare.
[edit] Diet
The eastern bearded dragon feeds on a variety of small vertebrates and invertebrates including crickets, small grasshoppers, worms, beetles, katydids, small mice, and small reptiles. In captivity they also eat a few vegetables. These include clover and dandelion flowers.
