Black Mamba
Dendroaspis polylepis
Quick answer
The black mamba is a long, slender African snake named for the dark interior of its mouth, not its grey-brown skin. It can reach 4.3 m (14 ft), move at speeds around 16 km/h (10 mph), and delivers potent neurotoxic venom. Despite its fearsome reputation, it usually flees from humans.

Speed and venom
Black mambas are among the fastest snakes in Africa, capable of raising a third of the body off the ground while moving. Their venom is primarily neurotoxic, affecting breathing and nervous function. Without antivenom, bites can be fatal, which contributes to their deadly reputation.
Behaviour and temperament
Contrary to myth, black mambas are shy and retreat when possible. They strike when cornered or threatened, often delivering multiple bites. The name comes from the inky black mouth lining displayed as a warning.
Habitat and range
Black mambas inhabit savannas, rocky outcrops, and woodland from Eritrea and Somalia south through East Africa to South Africa and Namibia. They shelter in termite mounds, rock crevices, and tree hollows.
Conservation and human conflict
Listed Least Concern, black mambas are not endangered but are killed out of fear in many areas. Education on snake behaviour, proper footwear, and antivenom access reduce unnecessary deaths on both sides.
