The eastern green mamba is a highly venomous snake with a slender body and bright green back. It lives in trees along the coasts of southern and East Africa. Although it is one of the most common green mambas, it is shy and usually hidden in leaves, so it is rarely seen.1

Iraruma

Ubumara busohokera mu menyo yayo y'ubumara cyangwa mu yandi menyo iyo iriye.

Ubumara bwayo bukora iki?

Its venom contains neurotoxins, which attack the nerves, and cardiotoxins, which damage the heart. Symptoms include swelling at the bite, dizziness, nausea, dehydration, laboured breathing and difficulty swallowing. These can progress to irregular heartbeat, convulsions and respiratory paralysis, which stops breathing and can be fatal. Paralysis may be mild or absent.1

A survey in southern Africa from 1957 to 1979 recorded 17 bites confirmed as eastern green mambas. Ten of these caused systemic envenomation, and no victims died. Bites are most common from September to February, the breeding season, when the snake is most irritable. The average dose able to kill a human is about 18 to 20 mg of venom, and one bite can deliver 60 to 95 mg (dry weight). In 2024, a YouTuber died after being bitten, following anaphylactic shock.1
