The mauve stinger is a small jellyfish that drifts in warm seas across much of the world. Its bell and tentacles are covered in stinging cells, so its stings hurt, even when the jellyfish is dead and washed up on a beach. Huge swarms of them can close beaches and damage fishing and fish farms.1

Hidup di

Tropical and warm temperate seas worldwide, most common in the North Atlantic and Mediterranean, and all around Australia1

Lautan Atlantik, Lautan Pasifik, Lautan Hindi, Laut Mediterranean, Laut Merah

Laman utama

It lives in the open sea, mostly between the surface and 150 m deep. Swarms are often carried by wind or currents onto beaches, where tourists avoid the water and fishers get stung while freeing their nets.1

Panjang

3 cm hingga 12 cm (1.2 in hingga 4.7 in)1

Kelajuan maksimum

Apa yang ia makan?

It eats small animals such as tiny crustaceans, fish eggs and fish larvae, and also collects microscopic plant plankton. It catches prey mainly by taking particles of food in its body, and adults will eat their own young.1

Cara mengenalinya

Adults have a bell 3 to 12 cm across.1
Colour varies from mauve and purple to pink, light brown and yellow.1
It has eight long tentacles and four long oral arms.1
Unusually for a jellyfish, both the bell and the tentacles carry stinging cells.1
When disturbed by waves or a ship's motion, it gives off short flashes of light at night.1

Sering dikelirukan dengan: Its common name purple-striped jelly can cause confusion with Chrysaora colorata. Stings from either can cross-react, so people who have been stung by one may react to the other.1

Sesungut yang menyengat

Ribuan sel penyengat kecil melepaskan sengat apabila sesuatu menyentuhnya.

Apa kesan bisanya?

This jellyfish stings rather than bites. Its stinging cells cause pain, redness, swelling and a rash, and the pain typically lasts 1 to 2 weeks. Less often, people feel dizzy or are sick or have diarrhoea, and skin rashes can return years later.1

Berapa bahaya ia kepada manusia?

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

Stings are common and painful, but they are generally not dangerous and there are no known deaths. A rare serious allergic reaction can happen, and a single case of Guillain–Barré syndrome, a serious nerve condition, has been linked to a sting; all symptoms in that case cleared within 6 months.1

Apa yang ia buat apabila takut?

Its stinging cells are used to defend it as well as to catch prey.1

Jika ia menyengat

The sting may possibly be relieved with compounds called hydroxyacetophenone and Symsitive, which stop the stinging cells firing. Seek medical help if a serious allergic reaction or other symptoms develop.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.
