Distribution: Yemen and Saudi Arabia. Size: Males 18 - 24 in. (46 - 61 cm) and females 13 in. (33 cm) long. Diet and Habitat: This arboreal creature lives in the low humid coastal plains, mountain slopes, and high plateaus of Yemen, as well as in the arid western coast of Saudi Arabia. It is considered one of the hardiest and most aggressive chameleons. Dramatic color changes help chameleons control body temperature, communicate with other chameleons, and camouflage themselves in their natural habitat. Their feet are great for grabbing and holding branches and their eyes can turn 180 degrees and point in two different directions at once. They catch insects and some, like this one, eat a variety of vegetation.
