## Definition

a long, very poisonous snake that lives in Africa. The black mamba and the green mamba are the best-known types, and their bite can be deadly without quick treatment.

For teachers: a highly venomous elapid snake of the genus Dendroaspis, native to sub-Saharan Africa. Includes the black mamba and several green species, noted for speed, arboreal agility, and potent neurotoxic venom.

## Examples

- The mamba moves fast through the tall grass.

- At dusk the green mamba lay motionless among the leaves, its bright body almost invisible until it struck with startling speed.
