Overview
The western green mamba (Dendroaspis viridis) is one of four mamba species and occupies forested regions of West Africa, distinct from its eastern counterpart by geography and some morphological differences. It is a fully arboreal elapid rarely seen on the ground.
It carries potent neurotoxic venom and is regarded as medically significant, though like other mambas it tends to avoid human contact when possible, favoring flight over confrontation.
How to identify it
A slender, brightly colored arboreal snake.
- Bright green dorsal coloration, sometimes with a yellow tinge on the head or anterior body
- Long, whip-like tail and slender body suited to climbing
- Head elongated and narrow, not sharply distinct from neck
- Smooth scales and round pupils
- Adults typically 1.8-2.4 m
Habitat & range
Found in lowland rainforest, forest edge, and dense woodland across West Africa, from Senegal to parts of Nigeria and Cameroon. It is strongly arboreal, favoring the forest canopy and dense shrub layers.
Behavior, diet & reproduction
Diurnal and an accomplished climber, feeding on birds, eggs, and small mammals in trees. It is generally reclusive, using speed and camouflage to avoid predators and threats. Reproduction is oviparous, with females laying clutches of eggs in tree hollows or leaf litter.
