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

Kako ga prepoznati

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

Često se miješa s: 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

Otrovna snaga

Tisuće sićušnih žarnih stanica okidaju se kad ih nešto dotakne.

Što radi njegov otrov kad ugrize ili ubode?

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

Opasnost za ljude: BolnoMože jako boljeti, ali gotovo nikad nije ozbiljno.

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

Ako ubode

Vinegar can be used to deactivate the stinging cells. If you have touched a large number of tentacles, get medical attention after exposure.1
Izađi iz vode i skini preostale krakove (rukavicama ili krpom).
Kod tropskih kubomeduza: prelij ubode octom najmanje 30 sekundi, pozovi pomoć i budi spreman započeti KPR (oživljavanje). Kod portugalske galije i većine drugih: isperi morskom vodom, a zatim stavi vruću vodu protiv boli.

Ostani na sigurnom

Nikad ne diraj, ne hvataj i ne zadirkuj divlju životinju, čak ni malu, i čak ni ako izgleda kao da spava ili je mrtva.
Ostavi joj prostora. Ako je sretneš, ne paniči, polako se odmakni i pusti je da ode svojim putem.
Ako te neka ubode: ne paniči, miruj, nazovi broj za hitne slučajeve (112, 000, 911) ili brzo idi u bolnicu. Zapamti kako je izgledala, fotografija pomaže.

Ne želi ti ništa loše. Otrov koristi za lov hrane ili za obranu i mnogo bi se radije sakrilo. Više o sigurnosti

Činjenice

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

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

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

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

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

Razbijač mitova

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

Istina: 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
