The Bushmaster is the largest and most deadly poisonous snake in Central and South America. It's poison is both neurotoxic and hemotoxic. Due the size of its fangs and the large amount of venom it is able to inject (called invenomation) the Bushmaster is easily the most deadly snake in terms of strength of poison. The term deadly also applies to the number of people killed per capita by a particular species of snake. A snake that likes to ambush its prey (such as the Bushmaster) is less likely to encounter people as opposed to the Ferdelance which is frequently found actively hunting rats around villages.
