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

  • 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

Kekuatan bisa

Tentakel penyengat

Ribuan sel penyengat mungil menembak saat sesuatu menyentuhnya.

Apa efek 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

Seberapa berbahaya bagi manusia?

Bahaya bagi manusia: MenyakitkanBisa 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 ambil sisa tentakel yang menempel (pakai sarung tangan atau kain).
  • Untuk ubur-ubur kotak tropis: siram sengatan dengan cuka minimal 30 detik, minta bantuan, dan bersiaplah melakukan CPR. Untuk ubur-ubur botol biru dan kebanyakan lainnya: bilas dengan air laut, lalu air panas untuk meredakan nyeri.

Selalu hubungi nomor darurat dulu (112, 000, 911). Ini panduan pertolongan pertama umum, bukan nasihat medis. Dasar-dasar pertolongan pertama

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

Pembongkar mitos

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

Faktanya: 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
