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？

This is a rear-fanged snake, meaning its fangs are at the back of the mouth, and it is described as mildly venomous. Its venom can paralyse small prey. Bites are expected to cause only mild to moderate local swelling and pain, with occasional bruising, numbness, redness or bleeding, but no tissue death (necrosis) and no whole-body (systemic) effects.1

牠對人有多危險？

對人的危險: 疼痛可能會非常痛，但幾乎從來不會很嚴重。

Bites are not expected to cause medically significant effects. Most cases are minor, but some are more severe and need hospital admission and treatment.1

牠害怕時會做什麼？

Usually sluggish and hard to provoke into striking, it may become hostile when threatened and display with its mouth wide open.1

如果牠咬人

Bites usually need no treatment beyond checking for infection and making sure tetanus protection is up to date. Anyone who develops local symptoms, such as signs of infection, should return for medical review. Some bites are more severe and need hospital care, so a careful assessment is needed before discharge.1
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

小知識

It is one of the rear-fanged snakes, and its venom is used to paralyse small prey.1

Its long, grasping tail lets it live entirely in trees, so it is described as purely arboreal.1

Despite its size, it is sluggish and makes no attempt to escape when handled.1

Hatchlings look very different from adults, being reddish brown with a green head.1

It hunts at night and rests during the day, coiled among the branches.1

A female lays between 7 and 14 eggs, which take about 85 days to hatch.1
