Black mamba

The black mamba (Dendroaspis polylepis; also called the black-mouthed mamba, southern brown mamba, or swart mamba) is a venomous elapid snake. It is the largest venomous snake in Africa and the second largest venomous snake in the world. Only the King Cobra is larger. Adult black mambas have an average length of 2.5 meters (8.2 ft) and a maximum length of 4.5 meters (14 ft). The black mamba receives its name from the black coloration inside of its mouth, rather than their skin color which is a gray to olive tone. The black mamba is the fastest moving snake in the world, capable of moving up to 20 km/h(12.5 mph). However it uses this speed to evade danger, rather than catch prey.
