怎样认出它

  • Large, heavy body with a short, broad, flat head1

  • Wholly black tail1
  • Narrow but prominent hood, which it spreads when threatened1

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 has not been well studied, but it is believed to be dangerously neurotoxic, meaning it attacks the nerves, as most elapids' venoms do. Laboratory tests on mice showed that its venom is very potent, with some of the lowest lethal doses recorded for any African cobra studied so far.1

它对人有多危险？

对人的危险: 非常危险不治疗可能会害死人。

It is secretive and seldom met by people. It is generally not aggressive and bites only when provoked.1

好消息：医生有药（抗毒血清）或治疗方法。1

它害怕时会做什么？

On land, when threatened, it rears up, spreads its hood and may hiss loudly, but it tends not to lunge forward. In water, it swims away quickly.1

如果它咬人

  • 让人保持安静不动，摘下戒指和紧身物品，尽快送医院：抗毒血清是治疗方法。

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
