The Wagler's Pit Viper is famously known as the "Temple Viper" found in the Snake Temple of Penang. This species is unique for its extreme difference between sexes.
Females: Grow large and bulky with a massive triangular head. Adults display a stunning, complex pattern of black background with thick yellow crossbands and green speckling.
Males: Remain very small, slender, and bright lime-green with red and white spots. They have a distinctively "rough" look due to strongly keeled scales.
Notes Behavior: These are the ultimate ambush predators. A female Wagler's Viper can sit motionless on a branch for weeks at a time. This makes them excellent display animals as they do not hide, but keepers must never be complacent—their strike is explosive.
Environment: They require high humidity but stagnant air must be avoided. Hydration is key.
Why Source This Species:
Cultural Icon: Owning the "Temple Viper" offers a great narrative for collectors and educational facilities.
Drastic Color Change: Watching a female transform from a green juvenile into a black-and-yellow adult is one of the most rewarding growth progressions in the hobby.
Ideal Display Subject: Because they rarely move, they are perfect for elaborately planted vivariums where they won't crush delicate plants.
