Reptiles of the East Usambara Mountains

The East Usambara Mountains are blessed with close to 30 species of spectacular reptiles. At least 16 of the reptiles occurring in the East Usambaras are found in the Eastern Arc mountains and nowhere else in the world. If you are fortunate, you may come across dragon-like chameleons with weird horns, or tiny little leaf-like chameleons on the forest floor. Snakes are plentiful, and while most are cryptic, they generally shy away from humans. Various geckos and lizards can be found, including an Agama species found darting along roads in the tea plantations, the gliding lizard (Holapsis guentheri) sometimes seen near Sigi and Amani, and along river courses larger ones like the monitor lizard (Varanus exanthematicus). Some beautiful chameleons and snakes are illegally procured for the international pet trade and we therefore caution you to not encourage this endeavor in the nature reserve.
