RHINO VIPER
Bitis nasicornis
DESCRIPTION
Rhino Viper (Bitis nasicornis) is commonly known as the African Rhino Viper and the Horned Viper. This striking snake is characterized by its vibrant coloration, featuring a mix of green, yellow, and reddish-brown hues, along with distinctive horn-like scales above its eyes. It is primarily found in the dense rainforests of Central and West Africa, where it exhibits a secretive and ambush-based hunting behavior, often lying in wait for unsuspecting prey.
FUN FACTS
- The Rhino Viper is named for the distinctive horn-like scales on its head, which are thought to play a role in mating displays and camouflage
- Despite their fearsome appearance and potent venom, they are generally not aggressive towards humans and will often flee if given the chance.|Rhino Vipers have a unique method of hunting; they can remain motionless for long periods, waiting for prey to come within striking distance
- Their venom is hemotoxic, which means it affects the blood and tissues of their prey, allowing them to subdue animals much larger than themselves
