Clinging jellyfish

Gonionemus vertens

名字的由来： It is called the clinging jellyfish because during the day it attaches itself to surfaces, such as seagrass, using the adhesive patches on its tentacles.1

需要看医生不要触摸很少致命，但被蜇了要去看医生。

The clinging jellyfish is a small jellyfish, with a bell only 1 to 3 cm across. It lives in shallow coastal waters across much of the Northern Hemisphere. Its sting can be strong in some areas, so it is worth knowing what it looks like.1

怎样认出它

Has a transparent bell lined with about 60 to 80 tentacles1
Gonads are orange, red or violet in females and yellow-brown in males1

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？

Its sting can cause pain, a swollen throat, chest tightness, muscle cramps, neuropsychiatric changes (effects on mood, thinking or behaviour) and anaphylactic shock, a severe allergic reaction.1

它对人有多危险？

对人的危险: 严重被蜇了要去看医生。死亡非常罕见。

In much of its range the sting is strong enough to cause serious symptoms. Stinging incidents have been reported from East Asia, Europe and the Atlantic coast of the United States. Off North America's northeast Pacific coast, its sting cannot be felt and it is considered harmless to people.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

Some scientists think the clinging jellyfish may be a group of closely related species, because its sting and body shape vary from place to place.1

The jellyfish appear once the water warms to about 17 to 18 °C, so they follow a yearly pattern and sometimes appear in large numbers at once.1

The medusa (jellyfish) stage usually lasts no more than three months, but the polyp stage can last for years.1

Polyps can split into several new polyps by budding.1

In Europe, the species is non-native and has been found in the Mediterranean and along the Atlantic coast from Portugal to Norway and Sweden.1

谣言粉碎机

谣言： The clinging jellyfish is harmless everywhere.

真相： Its sting is harmless off the northeast Pacific coast of North America, but it can be strong and dangerous in East Asia, Europe and the Atlantic coast of the United States.1
