Mauve stinger

Pelagia noctiluca

名字的由来： Pelagia comes from Greek and means "of the sea". Noctiluca comes from Latin and means "night light", because the jellyfish can glow in the dark.1

水母和海中蜇人生物

会蜇人的触手吃：什么都来一点

对人的危险: 很疼可能真的很疼，但几乎从不严重。

The mauve stinger is a small jellyfish that drifts in warm seas across much of the world. Its bell and tentacles are covered in stinging cells, so its stings hurt, even when the jellyfish is dead and washed up on a beach. Huge swarms of them can close beaches and damage fishing and fish farms.1

生活在

Tropical and warm temperate seas worldwide, most common in the North Atlantic and Mediterranean, and all around Australia1

首页

It lives in the open sea, mostly between the surface and 150 m deep. Swarms are often carried by wind or currents onto beaches, where tourists avoid the water and fishers get stung while freeing their nets.1

长度

最高速度

游泳, 粗略估计

它吃什么？

It eats small animals such as tiny crustaceans, fish eggs and fish larvae, and also collects microscopic plant plankton. It catches prey mainly by taking particles of food in its body, and adults will eat their own young.1

怎样认出它

Adults have a bell 3 to 12 cm across.1
Colour varies from mauve and purple to pink, light brown and yellow.1
It has eight long tentacles and four long oral arms.1
Unusually for a jellyfish, both the bell and the tentacles carry stinging cells.1
When disturbed by waves or a ship's motion, it gives off short flashes of light at night.1

常被误认为： Its common name purple-striped jelly can cause confusion with Chrysaora colorata. Stings from either can cross-react, so people who have been stung by one may react to the other.1

毒液之力

会蜇人的触手

一碰到东西，成千上万个小刺细胞就会发射。

它的毒液会造成什么？

This jellyfish stings rather than bites. Its stinging cells cause pain, redness, swelling and a rash, and the pain typically lasts 1 to 2 weeks. Less often, people feel dizzy or are sick or have diarrhoea, and skin rashes can return years later.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。

Stings are common and painful, but they are generally not dangerous and there are no known deaths. A rare serious allergic reaction can happen, and a single case of Guillain–Barré syndrome, a serious nerve condition, has been linked to a sting; all symptoms in that case cleared within 6 months.1

它害怕时会做什么？

Its stinging cells are used to defend it as well as to catch prey.1

如果它蜇人

The sting may possibly be relieved with compounds called hydroxyacetophenone and Symsitive, which stop the stinging cells firing. Seek medical help if a serious allergic reaction or other symptoms develop.1
离开水面，取下所有触手（戴手套或用布）。
热带箱水母：在蜇伤处倒醋至少 30 秒，呼救，并准备好做心肺复苏。僧帽水母和大多数其他水母：先用海水冲洗，再用热水止痛。

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。
如果被它蜇了：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 glows in the dark, and a description of its light was written by Pliny the Elder in 77 AD.1

Unlike most jellyfish, it has stinging cells on its bell as well as its tentacles.1

A seven-arm octopus has been recorded holding one of these jellyfish to use its sting as a defence.1

Swarms can cover tens of square kilometres and contain millions of jellyfish.1

It can eat microscopic plant plankton, which is highly unusual for a cnidarian.1

It has no polyp stage, a bottom-dwelling stage that most other jellyfish go through.1

谣言粉碎机

谣言： A dead jellyfish washed up on the beach is harmless.

真相： Even recently dead, stranded individuals can still sting.1
