对人的危险: 致命世界上最危险的动物之一。

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

毒液之力

咬伤

它咬的时候，毒液通过毒牙或牙齿出来。

它的毒液会造成什么？

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

它对人有多危险？

对人的危险: 致命世界上最危险的动物之一。

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

它害怕时会做什么？

It is shy and avoids people and predators, attacking only when it feels threatened, and it can flatten its neck into a hood.1

如果它咬人

Severe bites must be treated immediately on site, as they can quickly prove deadly.1

它不是冲着你来的。它用毒液捕猎或保护自己，而且它更愿意躲起来。更多安全知识

值得了解

事实

Males fight each other during the breeding season, usually entwining and pushing to pin each other's heads down. These fights can last several hours, but the snakes do not bite each other.1

Unlike most elapid snakes, which hunt actively, it often waits in ambush for its prey, a style more common among vipers.1

On average, an individual moves only about 5.4 metres per day, and it can stay in the same place for days.1

It has the least toxic venom of the three green mamba species, but it is still highly venomous.1

The oldest recorded eastern green mamba was a captive snake that lived 18.8 years.1

谣言粉碎机

谣言： It is an aggressive, fast-moving 'people-chaser'.

真相： It is shy and elusive, usually hidden in trees, and it generally avoids people. It attacks only when it feels threatened.1
