Black mambas are fast, nervous, lethally venomous, and when threatened, highly aggressive. They have been blamed for numerous human deaths, and African myths exaggerate their capabilities to legendary proportions. For these reasons, the black mamba is widely considered the world’s deadliest snake.
Black mambas live in the savannas and rocky hills of southern and eastern Africa. They are Africa’s longest venomous snake, reaching up to 14 feet in length, although 8.2 feet is more the average. They are also among the fastest snakes in the world, slithering at speeds of up to 12.5 miles per hour.
Just two drops of potent black mamba venom can kill a human, according to South Africa’s Kruger National Park. “Like cobras and coral snakes, the venom of a black mamba contains neurotoxins, It shuts down the nervous system and paralyzes victims, and without antivenom, the fatality rate from a black mamba bite is 100 percent.
