When it feels agitated, the fer-de-lance may vibrate its tail—the buzz is audible—before striking. These toxic snakes kill more people than any other snake in the Americas. [2] They also have heads two or three times the size of males relative to their size and proportionally bigger fangs (typically 2.5 cm), as well. The fer-de-lance has a venom that destroys muscle tissue which then results paralysis, which leads to heart failure and ends with death. On average, a fer-de-lance injects 105mg of venom in one bite, although a venom yield of up to 310mg has been recorded while milking them.

Kellett said one single bite from fer-de-lance snakes has enough venom to kill 32 people. Because of its proximity to human habitations and its defensive temperament, it is more dangerous to people than many other snakes. In the state of Lara, Venezuela, it is responsible for 78% of all envenomations and all snakebite fatalities (Dao-L., 1971). Herpetological Circular No. Curr Biol 22(17):733–740.
