Though the black mamba snake is actually olive brown in color, it gets its name from the blue-black on the inside of its mouth. The black mamba is widely considered the deadliest snake in the world.

The black mamba is native to southern and eastern Africa. It averages about 8.2 feet in length, though it can be as long as 14 feet. The black mamba is one of the fastest snakes in the world, traveling at a speed of up to 12.5 miles per hour. Typically, the black mamba uses its incredible speed to escape danger rather than to hunt down prey. Though it has a fearsome reputation, the black mamba is actually a shy, non-aggressive snake, preferring to avoid confrontation. The largest numbers of them are found in and around the Republic of Congo.
