怎麼認出牠

  • Large, heavy body with a short, broad, flat head1
  • Glossy brown, greyish-brown or reddish-brown body with black bands all along its length1
  • Pale yellow belly1
  • Wholly black tail1
  • Narrow but prominent hood, which it spreads when threatened1

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?

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

牠對人有多危險?

對人的危險: 非常危險如果沒有治療,牠可能會害死一個人。

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

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

如果牠咬人

  • 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。

一定要先打緊急電話(112、000、911)。這是一般急救指引,不是醫療建議。 急救基本知識

注意安全

  • 絕對不要碰、抓或捉弄野生動物,就算是很小的動物,就算牠看起來在睡覺或已經死了也一樣。
  • 給牠空間。如果遇到了,保持冷靜,慢慢往後退,讓牠自己離開。
  • 如果被牠咬了:保持冷靜,保持不動,打緊急電話(112、000、911)或趕快去醫院。記住牠的樣子,有照片會很有幫助。

牠不是想來抓你。牠用毒液來捕捉食物或保護自己,而且牠更想躲起來。 更多安全知識

牠有多長?

Banded water cobra 大約 2,8 m 長 (9,2 ft)大人的腳踏車 大約 1,8 m (5,9 ft)一台汽車 大約 4,5 m (15 ft)
跟 3 隻狗從鼻子接到尾巴一樣長跟 16 根香蕉頭尾相接一樣長可以在 43 秒內跑完 100 公尺(最快的人類需要 9.6 秒)
