The Puff Adder (Bitis arietans) is considered to be Africa's deadliest snake because it is responsible for the most human fatalities. Puff Adders reach an average length of around 1 meter, and they're solidly built with a wide girth. Color patterns vary depending on where they live, their habitats extend throughout Africa except for dense rain forests and deserts. The Puff Adder has large fangs and its venom is powerful enough to kill a grown man with a single bite. Puff Adders rely on camouflage for protection and lie still if approached. Because of this, people tend to step on them and get bitten. Many fatalities occur because bites are not treated correctly, leading to infection and gangrene.
