Silkback Bearded Dragon - Pogona vitticeps
The genus Pogona is in the subfamily Amphibolurinae of the lizard family Agamidae. Bearded dragons are characterized by their broad, triangular heads, flattened bodies, and rows and clusters of spiny scales covering their entire bodies. When threatened, bearded dragons will puff up their bodies and beards to ward off predators and make their somewhat dull spikes more dangerous. 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).
