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

Como recoñecelo

  • 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

Adoita confundirse con: 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

Poder da pezoña

Tentáculos que pican

Miles de pequenas células urticantes disparan cando algo as toca.

Que fai a súa pezoña?

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

Que perigoso é para as persoas?

Perigo para as persoas: DolorosoPode doer moito, pero case nunca é grave.

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

Se pica

  • Vinegar can be used to deactivate the stinging cells. If you have touched a large number of tentacles, get medical attention after exposure.1
  • Sae da auga e quita os tentáculos que queden (con luvas ou cun pano).
  • Para as cubomedusas tropicais: bota vinagre nas picaduras durante polo menos 30 segundos, pide axuda e prepárate para facer a RCP. Para as carabelas portuguesas e a maioría das outras: aclara con auga de mar e despois con auga quente para a dor.

Chama sempre primeiro ao teu número de emerxencias (112, 000, 911). Isto son consellos xerais de primeiros auxilios, non consello médico. Primeiros auxilios básicos

Mantente a salvo

  • Nunca toques, collas nin molestes un animal salvaxe, aínda que sexa pequeno e aínda que pareza durmido ou morto.
  • Déixalle espazo. Se atopas un, mantén a calma, recúa amodo e déixao ir polo seu camiño.
  • Se un te pica: mantén a calma, non te movas, chama ao teu número de emerxencias (112, 000, 911) ou vai rápido a un hospital. Lembra como era, unha foto axuda.

Non vai a por ti. Usa a súa pezoña para cazar comida ou para defenderse, e prefire con moito agocharse. Máis sobre como estar a salvo

Datos

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

Desmontamitos

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

Verdade: 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
