Photograph coming soon

We publish our own photographs rather than stock pictures, so this profile is waiting on a black mamba image from one of our guides. It will be added as soon as we have one worth showing — the field notes below are complete in the meantime.

Species profile

About the black mamba

The black mamba is not black: it is olive, grey or gunmetal brown, and takes its name from the ink-black lining of its mouth, displayed with the neck flattened when it is cornered. It can exceed three metres and can move at around 16 km/h in short bursts, making it the fastest snake in Africa.

Its real character is nervousness, not aggression. A mamba's first response to a person is almost always to escape to cover, and the great majority of bites follow attempts to catch or kill one. It is widespread in Tanzania's savanna and rocky country but rarely seen on a game drive.

Life in the wild

Behavior & relationships

Behavior

Diurnal and terrestrial, though it climbs well. Returns to a fixed lair each night. Rears, gapes and hisses only when escape is cut off.

Social life

Solitary. Males wrestle for access to females in the breeding season, pushing each other down without biting.

What makes it remarkable

Special features

The longest venomous snake in Africa, the fastest snake in the world over short distances, and a black mouth lining shown only in threat.
