Ambush Predator

Caucasus blunt-nosed vipers can grow over four feet long. Being so large, they are incredibly venomous and have the making of a perfect ambush predator. An ambush predator captures its prey with strategy, rather than strength or speed. Often, this viper will hide and wait for passing prey. Once it sees its next meal, it will launch a surprise attack on its victim.

Saving This Snake

Through the Saint Louis Zoo WildCare Institute Center for Conservation in Western Asia, for more than 10 years, Zoo staff have studied Caucasus blunt-nosed vipers that live in high elevations, specifically in Armenia. This research has helped Zoo staff model the vipers’ habitat at the Zoo after their environment in the wild. Armenia is considered a biodiversity hotspot, with an exceptional level of diverse and unique plants and animals.
