What Are the Most Venomous Snakes in the World?

9. Eastern Green Mamba

The eastern green mamba snake was first discovered in 1849. It primarily inhabits southern East Africa and is considered highly venomous. Despite its cheerful green appearance, its venom potency is reason enough to fear it, with an LD50 of .45 mg/kg. Bites often result in fatalities and symptoms of envenomation include dizziness, difficulty breathing, and neurological problems. Luckily enough, the green mamba is not especially aggressive and avoids confrontation when possible.
