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

Sesungut yang menyengat

Ribuan sel penyengat kecil melepaskan sengat apabila sesuatu menyentuhnya.

Apa kesan bisanya?

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

Berapa bahaya ia kepada manusia?

Bahaya kepada manusia: MenyakitkanIa boleh jadi sangat sakit, tetapi hampir tidak pernah serius.

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

Jika ia menyengat

Vinegar can be used to deactivate the stinging cells. If you have touched a large number of tentacles, get medical attention after exposure.1
Keluar dari air dan tanggalkan semua sesungut (dengan sarung tangan atau kain).
Untuk obor-obor kotak tropika: tuang cuka pada sengatan sekurang-kurangnya 30 saat, panggil bantuan dan bersedia melakukan CPR. Untuk bluebottle dan kebanyakan yang lain: bilas dengan air laut, kemudian air panas untuk menghilangkan sakit.

berguna untuk diketahui

Fakta

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

Pemecah mitos

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

Hakikat: 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
