Black mambas are fast, nervous, lethally venomous, and when threatened, highly aggressive... 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 (4.5 meters) in length, although 8.2 feet (2.5 meters) is more the average.
