Black mamba
The Black mamba (Dendroaspis polylepis), also commonly known as the common black mamba or the black-mouthed mamba[1] is a species of large, highly venomous snake belonging to the Elapidae family and is native to Africa. The black mamba is the longest venomous snake species in Africa, measuring between 2.5 and 3.2 m (8.2 and 10 ft) in length on average, and capable of growing to lengths of 4.45 m (14.6 ft).[2] This species is named for the black colouration inside the mouth rather than the colour of its scales, which varies from dull yellowish-green to a gun-metal grey. It is the fastest snake in the world, capable of moving at 4.32 to 5.4 metres per second (16–20 km/h, 10–12 mph).[3] Black mambas are fast, nervous, lethally venomous and, when threatened, highly aggressive. They have been blamed for numerous human deaths, and African myths exaggerate their capabilities to legendary proportions. For these reasons, the black mamba is widely considered to be the world’s deadliest snake.[3][4] Before the advent of black mamba antivenom, a bite from this species was 100% fatal, usually within about 20 minutes in very severe cases of envenomation.[3][5][6]
