Ctenophorus is a genus of lizards, commonly known as comb-bearing dragons, in the family Agamidae. The genus contains the most diverse group of dragon lizards in Australia. It is the largest group of Australian lizards and it has an extensive radiation in the arid zones.[2] Many of the species of Ctenophorus have been grouped by a similar morphology. The informal names and groupings within this genus — rock dragon, crevice-dragon, ground-dragon, sand-dragon, and bicycle-dragon — are named after the mythological creature, the dragon.
Lizards in the genus Ctenophorus may be confused with lizards in the genera Tympanocryptis and Diporiphora.[3]
Lizards of the genus Ctenophorus are known to display color polymorphism, more than one color type being found within a population. It is believed that color polymorphism in this group has evolved as a result of a combination of sexual selection and natural selection.[5]
