Behaviour

''P. barbouri'' often lives in small groups. During the day, it flattens its body to catch as much sun as possible. This way it can reach its preferred body temperature. During the night and in the early morning, ''P. barbouri'' has a dark colour. However, when it is basking, the body colour becomes brighter.

Reproduction

Adult females of ''P. barbouri'' glue their eggs under stones. Since additional females may deposit their eggs at the same location, as many as 50 eggs may be found together. At a temperature of , the young will hatch after approximately 55 days. The neonates measure .

Care and maintenance in captivity

''P. barbouri'' should be housed in pairs and needs a large terrarium which should provide many places to hide. Group breeding, however, is possible. The terrarium should be earth-based with a number of flat rocks present. It is important that there be some spot lights for basking. The daytime temperature should be around , while at night the temperature should drop to . In captivity, it can be fed
