The Eastern Green Mamba (Dendroaspis angusticeps) is a slender, arboreal snake native to the coastal regions of East Africa. Noted for its vibrant green coloration, it thrives in dense foliage, exhibiting remarkable agility. This species is highly venomous and primarily preys on birds and small mammals.

The Dendroaspis angusticeps, commonly known as the Eastern Green Mamba, is native to the eastern regions of Southern Africa. Its geographical distribution includes countries such as South Africa, Eswatini (formerly Swaziland), Mozambique, Tanzania, and Kenya. It is primarily found along the coastal regions of these countries.

The Eastern Green Mamba inhabits moist, subtropical, and tropical environments. It is typically found in coastal forests, lowland forests, and thickets. The species prefers areas with dense vegetation that provide ample cover and climbing opportunities, which are crucial for its arboreal lifestyle.

As an arboreal species, the Eastern Green Mamba is adapted to living in trees, where it can find its prey, which includes birds, eggs, bats, and small mammals. It plays an ecological role as both a predator and prey within its environment, contributing to the control of small vertebrate populations while also being a potential prey item for larger predators.
