Tropidolaemus wagleri (Say it: TROPE-id-oh-LEE-muss WAGG-lurr-ee) is a venomous pit viper species native to South-East Asia. It is sometimes referred to as the temple viper because of its abundance around the Temple of the Azure Cloud in Malaysia. This species is sexually dimorphic: the females grow to approximately 1 m (39 1⁄4 in) in total length, while males typically do not exceed 75 cm (29 1⁄2 in). They have a large triangular-shaped head, with a relatively thin body. They are almost entirely arboreal, and the tail is prehensile to aid in climbing.
