Also known as West African Green Mamba, Hallowell's Green Mamba
Western green mambas are sleek, lightning-fast arboreal snakes of West Africa that spend most of their lives high in the forest canopy. They hunt birds, bats, and tree-dwelling rodents by delivering a rapid, venomous strike before swallowing prey whole. Despite their potent neurotoxic venom, they are shy and reclusive, usually fleeing into dense foliage at the first sign of danger.
Highly venomous with potent neurotoxins; keep a wide distance and never approach.
Why it is dangerous
Injected neurotoxins cause rapid systemic paralysis, cardiac arrest, and respiratory failure that can be fatal without prompt antivenom treatment.
How to recognize a risky encounter
Recognizable by a long slender frame, vivid lime-green body scales outlined in black, a coffin-shaped head, and large dark eyes.
What to do
Maintain a safe distance of at least five meters, refrain from reaching into dense tree foliage, and contact emergency services or professional snake handlers if spotted near homes.
Responsible observation
Scanning Trees: Look along thick branches and leafy canopies in coastal West African forests where green scales offer total camouflage.
Giving Distance: Back away slowly if encountered, as they are exceptionally fast and capable of striking at head height.
