String jellyfish

Apolemia uvaria

只是会疼不要触摸会疼，但不会对你造成严重伤害。

会蜇人的触手吃：肉

The string jellyfish is not really one animal. It is a colony of tiny linked creatures that look and move like a single long string in the sea. It lives in oceans around the world, and its stinging tentacles can hurt people who touch them.1

生活在

Oceans worldwide, in the midwater; often at the surface, and also down to about 1,000 m deep1

大西洋, 地中海, 太平洋, 北海

首页

It lives in the open midwater of the ocean, far from the seabed, and is often found near the surface. In recent years large numbers have appeared around fish farms in Norway and Scotland, and in waters off South Devon and South East Cornwall.1

它吃什么？

It acts like a drift net, spreading its tentacles wide to catch plankton. It also preys on farmed salmon in some places.1

怎样认出它

A long central string, up to 3 m in total length1
Groups of pink and white tentacles that bunch together or spread out along the string1

Its colony is only 2 to 5 cm wide across1

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。

Its tentacles can sting people painfully.1

如果它蜇人

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

事实

Since 2025, string jellyfish have been multiplying in seas around Norway and Scotland, where they have caused mass deaths of farmed salmon.1

Each string jellyfish is a colony of specialised tiny organisms called zooids. They are permanently joined and cannot survive on their own.1

In rough seas, or where there are physical barriers, a colony can break into smaller pieces. These pieces can get into fish cages to reach farmed salmon.1

Rising sea temperatures and waste dumped from fish farms, which the jellyfish feed on, have been blamed for the increase.1

Colonies can be found at the surface and at depths of around 1,000 m.1

In September 2007, string jellyfish were spotted off South Devon and South East Cornwall, and for the first time off Plymouth. Changes in Atlantic ocean currents are the most likely cause.1
