如果牠咬人

讓傷者保持不動和冷靜，讓被咬的手臂或腿保持在和心臟一樣的高度，取下戒指和緊身的東西，並趕快送醫院。

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。

小知識

Its prehensile tail lets it grip branches, so it always rests where it can anchor itself.1

Its venom has been measured in a laboratory with a DL50 of 6.28 mg/kg, a standard measure of how toxic a substance is.1

It is a nocturnal snake that spends the day hidden in thick leaves, tree hollows or at the base of palm fronds.1

Young snakes stay low to the ground, where they hunt small frogs and lizards.1
