Mtunzini Fun Fact: Meet the Eastern Green Mamba. A shy and elusive species, the eastern green mamba is rarely seen. This elusiveness is usually attributed to its green colouration, which blends with its environment, and its arboreal lifestyle. It has also been observed to use “sit-and-wait” or ambush predation, like many  vipers, unlike the active foraging style typical of other elapid snakes. It preys on birds, eggs, bats, and rodents such as mice and rats.
