Like all pit vipers, T. wagleri has heat-sensing organs (called loreal pits) on its head below and in front of their eyes which are used to sense prey, even when they can’t see it. Juveniles and adult males prefer lizards, especially geckos. Females eat a more varied diet, including rats, birds, frogs and lizards, Needs only 3 meals a month.

REPRODUCTION: Viviparous (bears young alive). Litters contain 6-50 young.

CONSERVATION: IUCN Red list; Least Concern (LC)

REMARKS: They have hemotoxic, venom, preventing blood from clotting. Bites can cause local pain, swelling, bruising, and bleeding but bites are rarely fatal to humans.

The Temple of the Azure Cloud in Penang Island, Malaysia is known as Snake Temple. It was once filled with hundreds of Wagler’s pit vipers. Tourists would be photographed with the snakes. Locals collected the snakes, and, fortunately, the ones used for photography had their fangs removed.
