The black mamba is one of the world’s deadliest snakes— not only are they the fastest land snake, but their venom contains both neurotoxins and cardiotoxins. Before the creation of black mamba antivenin, a bite from this species was most likely fatal.

Unlike their name suggests, black mambas are actually a brownish color with olive or grey undertones. Their name comes from the coloration of the inside of their mouths, which is a deep, inky black.

These snakes are native to savannas, rocky hills, and woodlands in South and East Africa. They are Africa’s longest venomous snake, reaching up to 14 feet in length.
