Phil Roberts located an Arabian Spiny-tailed Lizard in Jubail when we were last birding there, a species I have seen here before but only once. The Lizards are a blue colour if not warmed up properly otherwise they reach a bright yellow colour. Spiny-tailed Lizard (Uromastyx spp.)is a medium to large sized, heavily built lizard with a spiny club like tail, which has been likened to a small living dinosaur. They are ground dwelling and live in some of the most arid regions of the planet including northern Africa, the Middle East, Arabia, Iran, Iraq, Afghanistan, Pakistan and north-western India. The Arabian Spiny-tailed Lizard Uromastyx aegyptia microlepis is most common in Saudi Arabia and is the one that occurs in the Eastern Province and is generally regarded as a subspecies of the Egyptian Spiny-tailed Lizard Uromastyx aegyptia. Due to the poor weather and distance the photo is not of great quality.
