Atlantic sea nettle

Chrysaora quinquecirrha

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 Atlantic sea nettle is a jellyfish that lives along the Atlantic coast of the United States. It has a bell-shaped body and stinging tentacles that it uses to catch food and to defend itself. Its sting is painful for people, but it is not strong enough to cause death except through an allergic reaction.1

它吃什么？

It feeds mainly on zooplankton, ctenophores, other jellies and sometimes crustaceans. It uses its stinging tentacles to immobilise prey, then moves the food into its gastrovascular cavity, a body cavity used for digestion.1

怎样认出它

Bell-shaped body that is usually semi-transparent1
Small white dots and reddish-brown stripes on the bell1
Typically pale, pinkish or yellowish, with deeper stripes near the edge of the bell1
Bells without stripes look white or opaque1
Smaller than the Pacific sea nettle1

常被误认为： It was often confused with several other Chrysaora species, so older reports of this jellyfish from other parts of the Atlantic and other oceans may be wrong. C. chesapeakei, found in estuaries on the Atlantic coast of the United States and in the Gulf of Mexico, was only recognised as a separate species in 2017. The Atlantic sea nettle is smaller than the Pacific sea nettle and has more variable colouring.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？

Each tentacle is covered in thousands of microscopic cells that fire venom-coated stinging filaments on contact. The venom can kill smaller prey or stun predators. In people, the sting most likely causes a painful but non-lethal rash that usually lasts about 20 minutes. Some earlier reported stings in the Philippines caused vascular insufficiency (poor blood flow) and mononeuritis (inflammation of a nerve).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。

Its sting is rated from moderate to severe. It is not potent enough to cause human death, except through an allergic reaction. While the sting is not particularly harmful, it can cause moderate discomfort.1

它害怕时会做什么？

When touched, its tentacles fire venom-coated stinging filaments that stun or deter a perceived predator.1

如果它蜇人

Misting vinegar over the affected area can neutralise the sting. This stops unfired stinging cells from firing and adding to the discomfort.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

Its body has no excretory or respiratory organs.1

Its stinging cells can also entangle or anchor prey, not only inject venom.1

Sea turtles, ocean sunfish and larger jellyfish are its main natural predators.1

It has a free-swimming stage and a polyp stage, and each reproduces in a different way.1

Its body is radially symmetrical, with a single mouth at the centre of one end.1

谣言粉碎机

谣言： The Atlantic sea nettle lives in the Atlantic and other oceans around the world.

真相： Earlier reports from other oceans were often mistaken, because this jellyfish was confused with other Chrysaora species. It is known from the Atlantic coast of the United States.1
