Curated Facts

Inland bearded dragons (Pogona vitticeps) have become popular in the reptile pet trade in the United States and Europe. As a consequence of large-scale breeding, several pathogens have been identified as causes of morbidity and mortality in colonies of these lizards, one of which is Microsporidium (Jacobson et al., 1998). Light microscopic examination of hematoxylin and eosin-stained tissue sections obtained from a bearded dragon that died showing nonspecific signs of illness revealed clusters of light basophilic microorganisms (2 to 3 um in diameter) packing renal tubules.

A problematic parasite of captive-bred inland bearded dragons (Pogona vitticeps) in the United States is Isopora amphiboluri. This coccidian was originally described from the bearded dragon (Pagona barbata [formerly Amphibolurus barbatus]) by Cannon (1967) and was redescribed from the inland bearded dragon by McAllister et al. (1995a). This parasite is firmly established in breeding groups of bearded dragons in the United Sates and its presence has been associated with mortality in neonate and juvenile lizards.

Inland bearded dragons live in harsh environments and are well adapted to eat whatever food is available. During lean seasons, they survive on nutrients and fat reserves stored in their large abdomens. If required, they will dig into the ground and remain dormant for long periods of time until favorable conditions, such as unusually hot or cold weather, improve.

Inland bearded dragons reach sexual maturity at 1 to 2 years of age. During courtship, a male will indicate his interest by rapidly bobbing his head. If the female is receptive to the male's overture, she will begin to bob her head, but at a slower rate.

Another interesting behavior is arm waving. The bearded dragon stands on three legs and waves one of its forelimbs in a slow circular pattern. One function of arm waving seems to be species recognition. Arm waving is also used to show submission.

Adult bearded dragons are territorial. As they grow, they establish social hierarchies in which aggressive and appeasement displays form a normal part of their social interactions. The beard is used for both mating and aggression displays. Both sexes have a beard, but males display more frequently, especially in courtship rituals.

The bearded dragons belong to the family Agamidae, which includes such well-known lizards the uromastyx (also called spiny-tails), water dragons, and the somewhat demonic-looking moloch or thorny devil. The genus Pogona (formerly part of the genus Amphibolurus) contains eight species of dragons, only four of which appear in the US pet trade, and only two of those with any regularity.
