Black mamba

Black mamba.
The black mamba (Dendroaspis polylepis) is a species of extremely venomous snake native to parts of Sub-Saharan Africa. It is the second-longest venomous snake after the king cobra; mature specimens generally exceed 2 metres (6.6 feet) and commonly grow to 3 m (10 ft). Specimens of 4.3 to 4.5 m (14.1 to 14.8 ft) have been reported. Its skin colour varies from grey to dark brown. The species is both terrestrial (ground-living) and arboreal; it inhabits savannah, woodland, rocky slopes and, in some regions, dense forest. It is diurnal and is known to prey on birds and small mammals. Over suitable surfaces, it can move at speeds up to 16 km/h (10 mph) for short distances. It is capable of striking at considerable range and may deliver a series of bites in rapid succession. Its venom, primarily composed of neurotoxins, is frequently fatal unless antivenom is administered. Despite its reputation as a formidable and highly aggressive species, the black mamba rarely attacks humans.
