Gaboon Viper

Bitis rhinoceros

The Leaves Have Eyes

The gaboon viper's color is a combination of brown and purple arranged in diamonds and stripes along its back, which provides camouflage. This pattern gives excellent coverage to blend into the leaves, making them very difficult to see on the ground.

About the Species

This snake is an ambush predator. It will hide among the leaves and wait for its prey to pass by.

Gaboon vipers are passive hunters, waiting concealed and camouflaged to strike at whatever small creatures pass within range. The Gaboon viper can control whether, and how much, venom is injected, so the result of a strike can range from no effect to quick death.
