Valentin's sharpnose puffer

Canthigaster valentini

名字的由来： It is named in honour of Dutch naturalist François Valentijn (1666–1727).1

需要看医生很少致命，但如果有人吃了它，要去看医生。

其他有毒动物

吃了有毒吃：什么都来一点碰了或吃了有毒，不注射毒液

对人的危险: 严重如果有人吃了它，要去看医生。死亡非常罕见。

Valentin's sharpnose puffer is a small reef fish with four black stripes across its back. It lives in warm seas across the Indian Ocean, the Red Sea and parts of the Pacific. It is special because its skin holds one of the most potent natural poisons known, which keeps most predators away.1

有毒还是有毒液？有毒液的动物通过咬或蜇注入毒液。有毒的动物是碰了或吃了会受害。这一种是碰了或吃了有害的。

怎样认出它

Four distinct black stripes, called saddles, run across its back.1
The head is blue-grey.1
The main body is white, speckled with blue-grey spots.1
The tail and fins show hints of yellow, and a rainbow streak sits behind the eyes.1

常被误认为： The filefish Paraluteres prionurus has similar colours and sometimes swims in schools with this puffer. It mimics the puffer's appearance for protection, but it is not toxic.1

毒力

吃了有毒

只有被什么东西吃掉时才有害。

它的毒会造成什么？

Its skin and other tissues contain tetrodotoxin, a neurotoxin, which attacks the nerves. It is one of the most potent naturally occurring toxins and is lethal to many species of fish. This makes the fish unpalatable to predators.1

它对人有多危险？

对人的危险: 严重如果有人吃了它，要去看医生。死亡非常罕见。

It is highly poisonous to eat.1

它害怕时会做什么？

It gulps water to puff its body up to three or four times its normal volume, and its toxic skin deters predators.1

如果有人碰了或吃了它

如果有人吃了它，或吃后出现症状：立刻拨打急救电话或中毒急救中心。

一定先拨打你的急救电话（112、000、911）。这里是一般急救指导，不是医疗建议。急救基础

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。
如果你碰了或吃了它：不要揉眼睛或嘴巴，洗手并就医。

它不是冲着你来的。它的毒只是为了不被吃掉。更多安全知识

值得了解

事实

Its tetrodotoxin is one of the most potent naturally occurring toxins, and it is lethal to many fish.1

A non-toxic filefish, Paraluteres prionurus, has evolved to look like this puffer, which helps it avoid predators.1

Its eggs are unpalatable, so predatory fish rarely eat them, and any swallowed eggs are quickly passed out again. This means the parents need not guard them.1

Juveniles of the grouper Plectropomus laevis also mimic its colours.1

Its eggs, at 0.68 to 0.72 mm across, are among the smallest in the puffer family Tetraodontidae.1

谣言粉碎机

谣言： Pufferfish hold their breath while they puff up.

真相： A 2014 study found that oxygen consumption actually increases while the fish is inflated. Oxygen intake through the gills is almost five times higher than normal.1
