What Is A Bearded Dragon

Pogona is a genus of reptiles containing eight lizard species (though some sources say nine or ten) which are often known by the common name bearded dragons. The name “bearded dragon” refers to the “beard” of the dragon, the underside of the throat, which can turn black and puff out for a number of reasons, most often as a result of stress, or if they feel threatened.  They are a semi-arboreal species, spending significant amounts of time on branches, 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. They can also be exhibited in zoos due to their hardy nature and easy care in comparison to other exotic reptiles.

The genus Pogona is in the subfamily Amphibolurinae of the lizard family Agamidae. Characteristics include broad, triangular heads and flattened bodies with spiny scales arranged in rows and clusters. These are found on the throat, which can be expanded when threatened, and at the back of the head. These scales are used to scare off predators, yet they are not very sharp. Bearded dragons display a hand-waving gesture to show submission (most often when acknowledging another bearded dragon’s territory), and a head-bobbing display to show dominance between dragons. Some have the ability to slightly change colour during rivalry challenges between males, in response to ambient temperature changes such as turning black to absorb heat, and other stimuli. Males grow up to 60 cm (24 in) long, and females up to 51 cm (20 in). Bearded dragons also produce a mild venom originating from primitive venom glands. Although generally harmless towards humans, it is effective towards smaller-sized animals.
