怎麼認出牠

Black above, with yellow bands across the back1
Yellow lips with black edges1
Black or bluish underside, sometimes speckled with yellow, and a yellow throat1
Can grow to about 240 to 270 cm long1
Has a triangular body cross-section1

常被誤認為： The mangrove snake can be confused with the banded krait, which has alternating black and yellow crossbands and a triangular body. The banded krait is extremely venomous, so treat any black and yellow banded snake with caution.1

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？

The snake has rear fangs and a venom gland linked to them. It has to chew to release the venom, which is released gradually. Its venom is weak, and the rear fangs are small, so it is hard for the snake to sink them into a person's arm or leg. Moderate bites have caused intense swelling.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。

It is considered mildly venomous. Moderate bites have caused intense swelling, but there has never been a confirmed death, as of 2016.1

牠害怕時會做什麼？

It is a potentially defensive snake that may strike repeatedly, even when captive bred.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

破解迷思

迷思： It is a dangerous killer because it looks like the banded krait.

真相： It is mildly venomous, and there has never been a confirmed death from its bite. Its look can be confused with the extremely venomous banded krait.1
