怎样认出它

The main colour is usually a shade of brown, sometimes pinkish or greyish, and occasionally olive green.1
It has 20 to 30 rhombic (diamond-shaped) blotches with pale edges running along its back.1
Oblique black bars on its sides are each topped by one or two black spots with pale centres, which look like eyes.1
The head has a V-shaped mark that may be solid black, or brown with a black outline.1
Northern populations may have no pattern at all, which makes them harder to identify.1

常被误认为： The common egg-eater (Dasypeltis scabra) is compared with this snake. Its colour pattern and behaviour may be a form of defensive mimicry, meaning it may resemble another animal to stay safe.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？

The venom is low in toxicity. Bites usually cause pain and minor swelling, with little tissue death (necrosis), and these symptoms usually fade within 2 to 3 days. Bites can still be serious, as in at least one case where a child needed a fasciotomy, a surgical operation to relieve pressure in a limb.1

它对人有多危险？

对人的危险: 很疼可能真的很疼，但几乎从不严重。

Most individuals are docile and seldom bite unless severely provoked. Bites can be serious, but there are no modern, well-documented cases of deaths from this species.1

它害怕时会做什么？

When seriously disturbed, it coils up, inflates its body so the dark markings stand out, hisses and puffs loudly, flattens the front of its body and neck, and strikes frantically.1

如果它咬人

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。

一定先拨打你的急救电话（112、000、911）。这里是一般急救指导，不是医疗建议。急救基础

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
