The spine-tailed sea snake is a sea snake that lives in shallow bays and estuaries in northern Australia, South-East Asia and New Guinea. It is unusual because it eats almost only fish eggs, and it has lost its fangs. It is one of the few sea snakes whose bite is unlikely to be dangerous to people.1

它吃什么？

It eats mostly the eggs of bottom-dwelling (benthic) fishes, and it has strong throat muscles that help it swallow them.1

怎样认出它

Its head shields are regular and symmetrical.1
Its smooth scales on the back are arranged in 17 rows around the middle of the body.1
It has 141 to 149 distinct belly scales (ventrals) along its body and 27 to 30 scales under its tail (subcaudals).1
Adults can reach a snout to vent length (the distance from the tip of the snout to the vent) of about 1 m.1

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？

Unlike most sea snakes, it has lost its fangs, and its venom glands have shrunk and are almost entirely non-functional. Its venom is much weaker than that of related sea snakes, because a small change in one of its venom genes reduces the venom's toxicity.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。

Because it has no fangs and its venom is very weak, its bite is unlikely to be a serious threat to people.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

值得了解

事实

It feeds almost exclusively on fish eggs, which is very unusual among sea snakes.1

Only one other species of sea snake, Emydocephalus annulatus, shares this egg-only diet.1

It has strong throat muscles, reduced teeth and a much smaller body than most other sea snakes, all linked to its special diet.1

It gives birth to live young, even though it is a snake that hatches its eggs inside the body.1
