Africa is home to a number of highly venomous snakes, including the black mamba, the puff adder and the Egyptian cobra. The black mamba may be the deadliest snake found on the African continent, with a venom so powerful that a single dose can kill as many as 12 adult humans.

From the perspective of actual harm done to humans, the puff adder is deadlier than the black mamba. Other examples of venomous African snakes include the boomslang, the Gaboon viper and the Mozambican spitting cobra, which can extend itself vertically and hurl its venom as far as 8 feet, posing a risk to human eyesight.
