Which snake genus includes the green mamba?

The genus Dendroaspis includes the green mamba.

Dendroaspis is the scientific genus containing the mambas. It includes the eastern green mamba, western green mamba, Jameson’s mamba, and black mamba. The green mambas are arboreal snakes that spend much of their time in trees and shrubs, where their green coloration provides camouflage.

The name Dendroaspis combines Greek roots associated with trees and asps, reflecting the tree-dwelling habits of several members. Mambas belong to the cobra family, Elapidae, and possess fixed front fangs rather than the folding fangs of vipers.

The black mamba is not usually black in colour; its name refers mainly to the dark interior of its mouth. Green mambas are separate species and are generally more associated with wooded habitats. All mambas are venomous, but colour, habitat, and geographic range help distinguish the species.
