Background: behaviors, "languages" and origins
Bearded Dragons get their name from their ability to "puff out" a throat pouch that has prominent spikes formed from modified scales. This "beard" can also change color, becoming jet black and even more impressive. Beards are not limited to males; the females will show off their beards as well, in a very interactive communication. Indeed, bearded dragons are very social animals. They have a rich gestural language, bobbing their heads at one another (watch video), gaping their mouths, flattening their bodies and tilting as they circle one another ("see how big I am!"), swishing their tails, using their tongue to check each other or their environment out, etc. They even have a variety of submissive gestures. For instance, both sexes will raise one arm and hold it stationary or slowly wave it in circles (watch video), evidently to signal "hey, its ME, stop harassing me, I'm harmless!" They rapidly establish a hierarchy and adapt to their caretakers, so the more extreme aggressive gestures become rare in captivity (unless you give them new territory to conquer). They are very curious and love being let out to investigate.
