The Mount Kenya bush viper is a venomous snake with a striking black and yellow pattern. It lives only in Kenya, in two small, separate areas of forest. Its bite can cause serious swelling and bleeding problems, so it is important to know it.1

怎样认出它

Ground colour is greenish-black to charcoal-black, with each scale tipped in yellow or yellowish-green, giving a speckled look.1
Some scales form a series of loops along the sides, which may join into zigzag patterns towards the back.1
The underside is yellow near the front, fading to purplish-black towards the rear and under the tail.1
Young snakes are mainly yellow with a white-tipped tail. They darken as they grow and reach adult colours at about 30 cm.1
Adults are usually 40 to 60 cm long, including the tail.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 powerful anticoagulants, which are substances that stop blood from clotting properly. A bite causes significant swelling and pain. Poor clotting may be severe enough to need blood transfusions.1

它对人有多危险？

对人的危险: 严重被咬了要去看医生。死亡非常罕见。

In the one recorded bite, a Kenyan collector was bitten on a finger by an adult snake. The bite caused significant swelling and pain, and he made a full recovery. The snakes are relatively large for their genus, so a bite should be taken seriously.1

它害怕时会做什么？

When captured, it strikes readily and struggles vigorously. It may also give a threat display, rubbing its coils and keeled scales together to make a loud hiss.1

如果它咬人

Because the venom can stop blood clotting, any bite should be treated as serious and needs urgent medical care. In the one recorded bite, a tourniquet was applied and an unknown antivenin was given, but the antivenin probably made no difference.1
让人保持安静不动，被咬的肢体与心脏保持同一高度，摘下戒指和紧身物品，尽快送医院。

注意安全

永远不要摸、抓或逗弄野生动物，即使是很小的，即使它看起来在睡觉或已经死了。
给它留出空间。如果遇到它，保持冷静，慢慢后退，让它走自己的路。
如果被它咬了：保持冷静，保持不动，拨打你的急救电话（112、000、911）或尽快去医院。记住它长什么样，拍张照片会有帮助。

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

Its coloration gives it excellent camouflage in the forest, so it is very hard to spot.1

Its speckled, looped pattern changes from juvenile yellow to adult black and yellow as it grows.1

It is arboreal, which means it lives in trees and bushes, moving slowly and deliberately among the branches.1

Captive snakes soon calm down, and their threat display disappears.1
