对人的危险: 很疼可能真的很疼，但几乎从不严重。

The lion's mane jellyfish is one of the largest jellyfish known, and its bell can be over 2 m across in the far north. It lives in cold northern seas, including the English Channel, the North Sea and the Irish Sea. Its long, trailing stinging tentacles can wash up on beaches in late summer and autumn.1

It stays mostly near the surface, at no more than 20 m deep, and drifts with ocean currents. Late summer and autumn are when most are seen, as currents sweep them onto beaches.1

怎样认出它

  • Bell is divided into eight lobes, giving it the look of an eight-point star1
  • Young ones are light orange or tan, darkening to red and purple as they grow1
  • Long, thin, trailing tentacles, with many more tentacles around the mouth1
  • Bell is often about 50 cm across in lower latitudes, and much larger in the far north1
  • Usually found alone, rarely in groups1

常被误认为： The blue jellyfish (Cyanea lamarckii) is sometimes found in the same waters. It is blue rather than red, and smaller, with a bell of about 10 to 20 cm across.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？

Its tentacles carry stinging cells, called nematocysts, which inject a sting when touched. The sting is very painful and feels like intense itching or burning, and it can cause temporary pain and redness where the skin was touched. Stings across large parts of the body can cause whole-body (systemic) effects, and medical attention is recommended in that case.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。

Stings are not known to be fatal in healthy people, and there is normally no real danger, though people with special allergies may be at risk. Rare severe stings in deep water can cause panic, which may lead to drowning. In July 2010, about 150 beachgoers were stung by the remains of one broken-up jellyfish on a beach in New Hampshire, US.1

如果它蜇人

  • Vinegar can be used to deactivate the stinging cells. If you have touched a large number of tentacles, get medical attention after exposure.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

1

The longest recorded tentacles were 36.6 m long, longer than a blue whale.1

2

Its tentacles can still sting for up to 25 days after they have detached from the jellyfish.1

3

Each of the eight lobes of its bell has about 70 to 150 tentacles, and it has around 1,200 tentacles near its mouth.1

4

The leatherback sea turtle feeds almost exclusively on lion's mane jellyfish in large numbers during summer around Eastern Canada.1

5

Unlike most jellyfish that drift in groups, the lion's mane is completely solitary.1

谣言粉碎机

谣言： The lion's mane jellyfish is the longest animal in the world.

真相： This claim was made on a TV show, but it was corrected. A bootlace worm reported in 1864 was said to be over 55 m long, and that report is doubted because bootlace worms can stretch well beyond their natural length. If that report is wrong, the lion's mane would be the longest animal.1

The female carries fertilised eggs in a tentacle, and they grow into larvae that settle on a hard surface and become polyps, which then produce young jellyfish called ephyrae.1
