Sinai Agama

Although drab and inconspicuous throughout much of the year, during the breeding season the male Sinai agama becomes instantly recognisable for its vivid sky-blue colouration. This colouration can extend over the entire head and body or just the head and throat, while the tail and body remain brown. The females and juveniles retain the brown colouration throughout the year, but usually have a red crescent-shaped spot on the flanks, behind the forelimb. Other distinctive features of this species include a large ear opening behind the eye, long limbs and a thin, cylindrical tail that is over one and half times the length of the body. (ARKive)
