Alamto, a Reptile Wonderland

A rare spider—tailed viper, whose spider-like tail serves as bait for birds, lives in the mountains of western Iran. From scorching deserts to shady oak forests, this harsh region is inhabited only by the hardiest: tree vipers, chameleon lizards, and snakes that can drink moisture directly from their scales. The unique footage shows for the first time the hidden life of these rare reptiles, who have to fight for survival every day.
