9 - Black Mamba
The most fearsome animal in all Africa may well be the black mamba, the giant venomous snake found throughout the southeastern portion of the continent. It gets its name from the black skin on the inside of its mouth, which it displays just before it strikes. These animals are usually quite shy, but can be extremely aggressive when confronted. When they do attack, they tend to strike their victims repeatedly, releasing a lethal mix of neurotoxin and cardiotoxin. In the past, a bite from a black mamba was 100 percent fatal. Now, that figure is decreasing due to the increased use of anti-venom throughout the continent.
