The bearded dragon's scientific name is Pogona Vitticeps and they are medium-sized lizards which are generally 12-24 inches in length from their head to tip of their tail. There are many different bearded dragon colors which sometimes can help tell you what environment they came from.
Heads - The bearded dragon's head is triangular shaped and contains rows of spikes that resemble thorns. Beneath their head the bearded dragon will have rows of spiked scales which, when puffed up, resemble a beard. These scales can also change colors, turning darker when breeding or provoked.
Body - The bearded dragon is supported by four stout legs and have well-muscled flat bodies with rows of spikes that run down each side of their abdomen. Their tail is generally half the length of their body and, unlike other lizards, will not fall off and regenerate when threatened.
