10. Black mamba (Dendropaspis polyepis)
The black mamba inhabits eastern and southern parts of Africa. The length of this snake is impressive 2.5 meters on average, being lightly colored to match the environment. It is very one of the fastest, nervous, easily provoked, and also very venomous snakes. When attacking, it injects large portions of venom, which kills an adult human within an hour. Due to lack of antivenom, deaths from black mamba are still frequent.
