怎样认出它

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

常被误认为： 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

毒液之力

咬伤

它咬的时候，毒液通过毒牙或牙齿出来。

它的毒液会造成什么？

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

它对人有多危险？

对人的危险: 很疼可能真的很疼，但几乎从不严重。

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

它害怕时会做什么？

It is a potentially defensive snake that may strike repeatedly, even when captive bred.1

如果它咬人

清洗咬伤处，让人保持冷静并就医。有些种类（比如非洲树蛇）可能几小时后才致命。

注意安全

永远不要摸、抓或逗弄野生动物，即使是很小的，即使它看起来在睡觉或已经死了。
给它留出空间。如果遇到它，保持冷静，慢慢后退，让它走自己的路。
如果被它咬了：保持冷静，保持不动，拨打你的急救电话（112、000、911）或尽快去医院。记住它长什么样，拍张照片会有帮助。

它不是冲着你来的。它用毒液捕猎或保护自己，而且它更愿意躲起来。更多安全知识
