What Is the Fastest Snake in the World?

The black mamba is the fastest snake in the world. It can travel at speeds of over 6.8 miles per hour over a distance of 43 feet. It is native to Africa, specifically around the grasslands and savannah regions of central, eastern and southern Africa.

Black mambas are also the longest species of venomous snakes in Africa. Their venom is a fast-acting, highly potent neuro- and cardiotoxin; however, they usually only strike as a last resort, preferring instead to flee. When one is cornered, it raises its head and flattens its neck to appear more threatening. When a black mamba strikes, it does so multiple times, injecting large amounts of venom that was 100 percent fatal until the invention of antivenom.
