The black-banded sea krait is a sea snake with venom that is reportedly ten times stronger than a cobra's. It lives in the warm western Pacific Ocean, mostly around coral reefs. It spends much of its life in water but needs to come up to breathe.1

It frequents coral reefs and searches their tight spaces. Near shore it gathers in numbers, breeding in narrow reef cracks and caves. In some warm years it moves into sea caves and tide pools on the Ryukyu cliffs in Japan.1

牠吃什麼？

It is too slow to chase prey in open water, so it explores small spaces within coral reefs to find hidden fish and other animals of suitable size. Some hunting is done in groups, with bluefin trevally waiting nearby to catch fish flushed out by the snake.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 bite is highly venomous and paralyses the prey. The venom glands are located behind the eyes.1

牠對人有多危險？

對人的危險: 非常危險如果沒有治療，牠可能會害死一個人。

Its venom is reportedly ten times stronger than cobra venom, so any bite should be treated as serious.1

牠害怕時會做什麼？

It prefers to save its energy and venom for hunting, so it strikes only as a very last resort when cornered, threatened or provoked.1

如果牠咬人

加壓固定法：用彈性繃帶緊緊包住咬傷處，再往上包住整條手臂或腿，用夾板固定，並讓傷者完全不動，直到救援抵達。
把傷者帶離水中，趕快送醫院。

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

Its venom is reportedly ten times stronger than that of a cobra.1

It has been observed hunting in cooperative 'alliances' with bluefin trevally, which pick off small fish that the snake flushes from the coral.1

In some warm years, large numbers gather in sea caves and tide pools on the Ryukyu cliffs in search of fresh water and possibly to mate.1

Although it lives in the sea, it lays its eggs on land.1

In southern Japan its meat is used in a winter broth called irabu-jiru, which is said to taste like miso and a little like tuna.1

Its northward spread into waters near South Korea is linked to climate change, which has damaged its habitat.1
