The Australian box jellyfish is one of the most venomous animals in the world. It lives in the warm coastal waters of northern Australia and nearby parts of Southeast Asia. Its sting can cause extreme pain and can be deadly, so it is important to know how to recognise it and what to do.1

Co renconuscher el

  • The bell is box-shaped and pale blue, with faint markings.1
  • The bell is usually about 16 cm across and can reach 35 cm.1
  • A cluster of 15 tentacles hangs from each of the four corners of the bell.1
  • It is almost completely transparent, so it is very hard to see in the water.1
  • When hunting, its tentacles can stretch to about 3 m long.1

Tge fa ses tissi?

Its venom makes cells porous, so potassium leaks out of them. This causes hyperkalemia, a dangerous build-up of potassium in the blood, which can lead to heart and circulation failure. Stings cause excruciating pain and a burning feeling, and an untreated victim can die within two to five minutes.1

Quant privlus è el per umans?

Privel per umans: MortalIn dals animals ils pli privlus dal mund.

At least 64 deaths have been recorded in Australia. Most deaths in recent decades have been children, because their smaller bodies are at higher risk. Most stings are mild, but one animal's venom is said to be enough to kill 60 adults.1

Bunas novitads: ils medis han in medicament (antiserum) u in tractament per quai.1

Sch'el piztga

  • Diluted acetic acid, such as vinegar, is the recommended treatment, because it deactivates stinging cells that have not yet fired. Some North American toxicologists advise applying it for around 30 seconds. Pressure bandages are no longer recommended, because they can cause more stinging cells to fire.1
  • Va or da l'aua e prenda davent las tentaclas (cun manetschas u cun in tschop).
  • Tar medusas cubicas tropicalas: versa aschieu sin las piztgadas durant almain 30 secundas, clama agid e sajas pront da far ina reanimaziun. Tar galeras portugaisas e las bleras autras: lava cun aua da mar, lura cun aua chauda cunter las dolurs.

Resta en segirezza

  • Na tutga, na piglia e na tizza mai in animal selvadi, gnanc in pitschen, ed era sch'el para da durmir u d'esser mort.
  • Dà spazi a l'animal. Sche ti scuntras in, resta calm, va plaun enavos e lascha ir el per sia via.
  • Sch'in tal animal ta piztga: resta calm, na ta mova betg, clama tes numer d'urgenza (112, 000, 911) u va spert en in ospital. Ta regorda co ch'el veseva or, ina foto gida.

El n'ha betg quai sin tai. El dovra ses tissi per pigliar nutriment u per sa defender, e sa zuppa bler pli gugent. Dapli davart la segirezza

Fatgs

1

It has four clusters of eyes with 24 eyes in total, even though it has no central nervous system.1

2

Its tentacles are covered with millions of stinging cells that fire microscopic darts carrying venom.1

3

Its only known predators are green sea turtles and leatherback turtles, whose thick skin protects them from its stings.1

4

It is attracted to blue light, which makes it stream out its tentacles, while black objects make it move away.1

5

From certain angles, its pale blue bell looks like a human head or skull.1

6

Its name, 'hand of death', comes from its four appendages, which look like hands.1

Destructur da mits

Mit: Pressure bandages are the best first aid for a box jellyfish sting.

Vardad: Pressure bandages were used until 2005, but health authorities no longer recommend them because they can trigger more venom release. Diluted vinegar is the recommended treatment.1
