Eastern bearded dragon

The Eastern bearded dragon is an agamid lizard found in wooded parts of Australia. Pogona barbata is the most massive of the eight recognized species within the Pogona genus. Adult males can grow to about 60 cm from the snout to the tip of the tail, while females may reach 50 cm in overall length. The head is large and triangular in shape. The throat is covered with spiny, dark grey scales which can be raised to form an impressive "beard". Several groups of even longer spiny scales are located at the back of the head, the corners of the mouth, the external ear openings, and running posteriorly along both sides of the abdomen. The thorax and abdomen are relatively slender and flattened dorsoventrally.
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 the animal matures, it develops a subtle pale yellow, blue, or green tinge on the forepart of its head. If excited and at higher temperatures head, flanks and legs have a yellowish to orange colour. Usually however they are rather dark, from yellowish to grey and black. The inside of the mouth is generally a bright yellow colour. Pogona barbata resembles its close relative, the smaller Central bearded dragon, but may be distinguished from the latter by its less robust body and the row of spines along the lateral edge of the body, which continues over the forearm.
