怎样认出它

Usually chrome yellowish in colour, with dark greenish crossbands on the body1
The dorsal pattern does not extend onto the belly1
Short head with bands of the same colours1
Adults are about 50 to 100 cm long1
Out of water, the body looks faintly yellow1

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？

Not much is known about this species' venom. Its LD50 in mice, the dose that kills half of the test animals, is 0.24 mg/kg when injected into muscle.1

它对人有多危险？

对人的危险: 非常危险不治疗可能会害死人。

It is described as extremely venomous. Usually those bitten are fishermen handling nets, and only about one quarter of those bitten are envenomated, meaning venom is injected, because the snake rarely injects much venom.1

它害怕时会做什么？

It has a timid temperament and would normally have to be severely mistreated before it bites.1

如果它咬人

加压固定法：用有弹性的绷带紧紧缠住咬伤处，再缠满整条肢体，用夹板固定，让人完全不动，直到救援到来。
把人带出水面，尽快送医院。

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

Its mouth is very small, which suits life in the water.1

谣言粉碎机

谣言： Belcher's sea snake, often called the hook-nosed sea snake, is the most venomous snake in the world.

真相： This idea spread from a 1996 book, which lumped together toxicity results from different test methods. Venoms can only be compared within the same testing method. The most venomous sea snake is Dubois' seasnake (Aipysurus duboisii).1
