Bearded dragons are found across Australia, typically in arid or semi-arid environments. They are the most common found worldwide in the pet-trade. Central Bearded Dragon has an average captivity lifespan of 8-10 years. Their average length from nose to tail tip is between 18 and 22 inches. This can vary in both larger and smaller bearded dragons. There are several subspecies of the bearded dragon. Depending in the species, bearded dragons can be found in different colors (grey, orange, light brown or black). When threatened or alarmed bearded dragons puff out their beards and face intruders with an open mouth. They also expand their bodies by inhaling air, making them seem larger. The bobbing of their head or whole body is a sign of dominance. Bearded dragons can change colors when aggressive or threatened and also regulate their body temperature through changing their color; they become lighter in hot weather and darker in cooler weather.
Although they are advertised by pet stores as “great beginners pets”, bearded dragons have very specific dietary and housing requirements in order for them to thrive in captivity. They need proper UVB lightening, heat, a complex diet and plenty of space.
