Kuhusu jina: Pelagia comes from Greek and means "of the sea". Noctiluca comes from Latin and means "night light", because the jellyfish can glow in the dark.1

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

Anaishi

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

Bahari ya Atlantiki, Bahari ya Pasifiki, Bahari ya Hindi, Bahari ya Mediterania, Bahari ya Shamu

Nyumbani

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

Urefu

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

Kuogelea, makadirio

Hula nini?

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

Jinsi ya kumtambua

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

Mara nyingi huchanganywa na: 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

Nguvu ya sumu

Mikono inayodunga

Maelfu ya seli ndogo za kudunga hufyatuka kitu kikizigusa.

Sumu yake hufanya nini?

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

Ana hatari gani kwa watu?

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

Hufanya nini akiogopa?

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

Akidunga

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
Toka majini na uondoe vipande vya mikono iliyonata (kwa glavu au kitambaa).
Kwa yavuyavu sanduku wa kitropiki: mimina siki kwenye sehemu zilizodungwa kwa angalau sekunde 30, omba msaada na uwe tayari kufanya CPR. Kwa mabotoli ya bluu na wengine wengi: suuza kwa maji ya bahari, kisha maji ya moto kupunguza maumivu.

Daima piga namba ya dharura kwanza (112, 000, 911). Huu ni mwongozo wa jumla wa huduma ya kwanza, si ushauri wa kitabibu. Misingi ya huduma ya kwanza

Kaa salama

Kamwe usimguse, kumkamata wala kumchokoza mnyama wa porini, hata akiwa mdogo, na hata akionekana amelala au amekufa.
Mpe nafasi. Ukikutana naye, tulia, rudi nyuma polepole na umwache aende zake.
Akikudunga: tulia, usitikisike, piga namba yako ya dharura (112, 000, 911) au nenda hospitali haraka. Kumbuka alivyoonekana, picha husaidia.

Hakuwindi wewe. Hutumia sumu yake kukamata chakula au kujilinda, na hupendelea zaidi kujificha. Zaidi kuhusu kukaa salama

inafaa kujua

Ukweli

It glows in the dark, and a description of its light was written by Pliny the Elder in 77 AD.1

Unlike most jellyfish, it has stinging cells on its bell as well as its tentacles.1

A seven-arm octopus has been recorded holding one of these jellyfish to use its sting as a defence.1

Swarms can cover tens of square kilometres and contain millions of jellyfish.1

It can eat microscopic plant plankton, which is highly unusual for a cnidarian.1

It has no polyp stage, a bottom-dwelling stage that most other jellyfish go through.1

Kuvunja dhana potofu

Dhana potofu: A dead jellyfish washed up on the beach is harmless.

Ukweli: Even recently dead, stranded individuals can still sting.1
