Jameson's mamba is a highly venomous snake that lives in the forests and woodlands of equatorial Africa. It spends much of its time in trees and is often found near towns, farms and plantations. Its venom attacks the nerves, so it is a snake to treat with respect and keep well away from.1

牠吃什麼？

Mainly eats birds and tree-dwelling mammals such as squirrels, shrews and mice. Smaller individuals under 100 cm also eat lizards and toads. It is thought to wait motionless and strike at prey, though this has not been observed.1

毒液力量

咬

咬的時候，毒液會從毒牙或牙齒出來。

牠的毒液有什麼作用？

The venom is highly neurotoxic, meaning it attacks the nerves, and also contains cardiotoxins, which affect the heart. Bite pain and swelling are followed by chills, sweating, abdominal pain and vomiting. Later symptoms can include slurred speech, difficulty breathing and paralysis.1

牠對人有多危險？

對人的危險: 致命世界上最危險的動物之一。

The World Health Organization classes it as a Snake of Medical Importance in sub-Saharan Africa, although few bites are recorded. Deaths have been recorded within three to four hours of a bite. An unconfirmed report describes a child dying within 30 minutes. Access to antivenom is difficult in some areas, and workers in palm oil plantations have died after falling from trees when they met one in the canopy.1

好消息：醫生有藥（抗毒血清）或治療方法。1

牠害怕時會做什麼？

When threatened, it flattens its neck like a cobra, and it will usually try to escape rather than attack.1

如果牠咬人

Apply a pressure bandage, keep the victim as still as possible and get them to a hospital or clinic quickly. An arterial tourniquet may help because of the neurotoxic venom. Antivenom is the main treatment, and tetanus toxoid is sometimes given.1
讓傷者保持不動和冷靜，取下戒指和緊身的東西，並趕快送醫院：抗毒血清就是治療方法。
