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

Vive en

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

Inicio

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

Que come?

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

Como recoñecelo

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

Adoita confundirse con: 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

Poder da pezoña

Tentáculos que pican

Miles de pequenas células urticantes disparan cando algo as toca.

Que fai a súa pezoña?

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

Que perigoso é para as persoas?

Perigo para as persoas: DolorosoPode doer moito, pero case nunca é grave.

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

Que fai cando ten medo?

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

Se pica

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
Sae da auga e quita os tentáculos que queden (con luvas ou cun pano).
Para as cubomedusas tropicais: bota vinagre nas picaduras durante polo menos 30 segundos, pide axuda e prepárate para facer a RCP. Para as carabelas portuguesas e a maioría das outras: aclara con auga de mar e despois con auga quente para a dor.

Mantente a salvo

Nunca toques, collas nin molestes un animal salvaxe, aínda que sexa pequeno e aínda que pareza durmido ou morto.
Déixalle espazo. Se atopas un, mantén a calma, recúa amodo e déixao ir polo seu camiño.
Se un te pica: mantén a calma, non te movas, chama ao teu número de emerxencias (112, 000, 911) ou vai rápido a un hospital. Lembra como era, unha foto axuda.

Non vai a por ti. Usa a súa pezoña para cazar comida ou para defenderse, e prefire con moito agocharse. Máis sobre como estar a salvo

Datos

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

Desmontamitos

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

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