Black Mamba is one of the most feared snakes in the world. Attaining a length of over 4 meters, capable of speeds of up to 15km/hr (very fast for a snake) and equipped with an extremely fast working neurotoxin make this snake formidable. However it is not aggressive. It has a nervous disposition and when threatened bites readily and repeatedly. Multiple bites are almost always fatal. The snake is not black but rather grey to olive in colour with a black lining to the inner mouth. The body is long and slender and the head is coffin shaped with a long gape.
