The black mamba (Dendroaspis polylepis) is a venomous snake endemic to sub-Saharan Africa. It takes its common name not from the colour of its scales, but from the interior of its mouth, which is inky-black.It is the longest species of venomous snake on the African continent, with a length typically ranging from 2 meters (6.6 ft) to 3 meters (9.8 ft) and up to 4.3 to 4.5 meters (14.1 to 14.8 ft).ts bites can deliver about 100â120 mg of venom on average and the maximum dose recorded is 400 mg. It is reported that before antivenom was widely available, the mortality rate from a bite was nearly 100%. The bite of a black mamba can potentially cause collapse in humans within 45 minutes, or less.
