毒液力量

咬

咬的時候，毒液會從毒牙或牙齒出來。

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。

Although it is venomous, few deaths have been recorded from its bites. It rarely strikes, because it tends to flatten, lie still or flee instead, and its rear fangs make a strong bite on a large object difficult.1

牠害怕時會做什麼？

At cooler temperatures it flattens its neck and body and lies still. At higher temperatures it is more likely to flee.1

如果牠咬人

清洗咬傷處，讓傷者保持冷靜，並且就醫。有些種類（例如非洲樹蛇）可能在幾個小時後才致命。

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

值得知道

小知識

It stores toxic steroids in special glands on the back of its neck, taken from the toads it eats, and it is resistant to their effects.1

Females can pass the stored toad toxins to their offspring through the egg yolk and the egg membranes.1

Two rows of neck glands give it a chemical defence, a process called kleptotoxisism, meaning it steals toxins from its prey and uses them for its own protection.1

Its fangs are at the back of its mouth, which makes a strong strike on a large animal difficult.1
