Pogona is a genus of reptiles containing eight lizard species, which are often known by the common name bearded dragons. The name “bearded dragon” refers to the “beard” of the lizard, the underside of the throat which turns black if they are stressed or see a potential rival. They are adept climbers, spending time on branches and in bushes and near human habitation. Pogona species bask on rocks and exposed branches in the mornings and afternoons. They are found throughout much of Australia in a wide range of habitats such as deserts, shrublands and Eucalyptus woodlands.
Several species of this genus, especially the central bearded dragon, are often kept as pets or exhibited in zoos due to their hardy nature and easy care in comparison to other exotic reptiles. source
