String jellyfish

Apolemia uvaria

只是會痛不要碰會痛，但不會對你造成嚴重傷害。

會螫人的觸手吃：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

分布在

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

首頁

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

長度

3 m (9,8 ft)1

最高速度

大約 3 km/h（1,9 mph）

牠吃什麼？

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

怎麼認出牠

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
A gas float at the front of the colony, followed by a set of swimming bells that push it forward1
Its colony is only 2 to 5 cm wide across1

毒液力量

會螫人的觸手

有東西碰到時，成千上萬個小小的刺細胞就會發射。

牠對人有多危險？

對人的危險: 疼痛可能會非常痛，但幾乎從來不會很嚴重。

Its tentacles can sting people painfully.1

如果牠螫人

離開水裡，把觸手拿掉（戴手套或用布）。
熱帶箱形水母：在螫傷處倒醋至少 30 秒，求救，並準備好做心肺復甦術（CPR）。藍瓶水母和大多數其他水母：用海水沖洗，再用熱水止痛。

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。
如果被牠螫了：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

牠有多大？

牠有多長？

跟 3 隻狗從鼻子接到尾巴一樣長跟 17 根香蕉頭尾相接一樣長可以在 60 秒內游完一座大游泳池（50 公尺）

String jellyfish 跟「你」比起來有多大？

只是在你的瀏覽器裡做算術。什麼都不會儲存，也不會傳送到任何地方。

牠有多快？

一個正在游泳的人 大約 3 km/h (1,9 mph)

String jellyfish 大約 3 km/h (1,9 mph)

奧運游泳選手 大約 8 km/h (5 mph)

小知識

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
