The South American sea nettle is a large jellyfish with a red-brown bell and long, spiralling arms. It drifts in the open ocean along both the Pacific and Atlantic coasts of South America. Its stinging tentacles catch the tiny animals it eats.1

怎样认出它

Red-brown bell1
Long, spiralling arms1
Thin outer tentacles that surround inner tentacles which are often white and fluffy in appearance1
Most mature individuals have a bell 25 to 40 cm across1

常被误认为： It was historically confused with C. hysoscella. That species is now known to be restricted to the northeast Atlantic, so it is not found in South American waters.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。

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

Its bell can grow up to 1 metre across, but most adults are much smaller.1

Crab larvae may form a parasitic relationship with it, using it for food and shelter.1

A single polyp can produce between 3 and 10 young jellyfish called ephyrae in about 7 to 10 days.1

Its population has increased in recent years, which may be linked to climate change and major changes to ocean ecosystems.1

Its stinging tentacles are used to catch its prey, and the adults are eaten by sea turtles and some fish.1

谣言粉碎机

谣言： It is the only sea nettle found in South America.

真相： Despite its common name, it is not the only sea nettle in the region. C. lactea is another sea nettle found there.1
