咬伤吃：肉

The yellow-lipped sea krait is a highly venomous sea snake. It lives in tropical waters of the Indo-Pacific, between the Indian Ocean and the Pacific. It spends much of its time underwater hunting, but it comes ashore to digest food, rest and breed.1

首页

It lives in coastal waters and on the land beside them, and adults spend about half their time on land. People often meet it because it turns up in the water intake and exhaust pipes of boats, and it is drawn to lights in hotels and other buildings on coasts.1

它吃什么？

It mainly eats eels, and also small fish. It usually hunts alone, but sometimes hunts in groups with giant trevally and goatfish, flushing prey out of narrow crevices and holes.1

怎样认出它

Black head with a yellow upper lip and snout. The yellow extends back above the eye.1
Upper body is a bluish grey, with black rings of about the same width along its length. The belly is yellowish.1
Paddle-shaped tail, adapted for swimming.1
Between 21 and 25 rows of overlapping scales run along the middle of the body.1

常被误认为： The yellow-lipped New Caledonian sea krait is similar. It has fewer rows of scales, and its scales narrow or fail to meet. The dark bands of the yellow-lipped sea krait meet across the belly.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？

Its venom is a very powerful neurotoxic venom, which attacks the nerves. It blocks signals between nerves and muscles, which causes paralysis. In mice, lethal doses caused lethargy, paralysis and convulsions in quick succession before death.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。

Fewer bites are recorded from this snake than from cobras and vipers, because it is less aggressive and tends to avoid people. Bites usually happen when it is accidentally grabbed. Most sea snake bites happen when fishermen try to untangle the snakes from their nets.1

它害怕时会做什么？

It is not aggressive and only attacks when it feels threatened, and its tail moves and looks like its head, which can fool predators.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

Eels from New Guinea, where this snake lives, tolerated doses of its venom about 750 times larger than eels from the Caribbean, where it does not live.1

Snakes moved 5.3 km away from their home islands in Fiji all returned to their home islands, taking an average of 30.7 days.1

It hunts underwater but returns to land to digest food, shed its skin and breed.1

In the Philippines, these snakes are caught for their skin and meat. The meat is smoked and exported for use in Japanese cuisine.1

Females are much larger than males, with an average length of 142 cm compared with 87.5 cm for males.1

It is the most common sea krait found in New Zealand, where it is protected under the Wildlife Act 1953.1

谣言粉碎机

谣言： Sea snakes are aggressive and attack people often.
