The Irukandji jellyfish is a tiny box jellyfish with a sting that can cause a serious illness called Irukandji syndrome. It lives in the open water near Australia, and it is hard to spot because it is so small.1

Sihlala
Open water near Australia, with most reported incidents in Australia, especially North Queensland1

Ekhaya
It lives in open water. Most reported stings happen in Australia during the warm summer season. Swimmers in open water near North Queensland were the first people recorded with this syndrome.1
Ubude

Esona santya siphezulu
malunga ne-5 km/h (3,1 mph)

Sitya ntoni?
Muscle cells in the tentacles bring food to the mouth, where it enters a stomach-like cavity and is digested. Its prey changes as it grows, from small invertebrates such as zooplankton and crustaceans to fish.1

Indlela yokusiqaphela

  • The bell is square-shaped and very small, about 12 mm high and 30 mm across.1
  • It has four long tentacles, one from each corner of the bell.1
  • The tentacles range from 5 to 50 cm long.1
  • Its small size means it often goes unseen in open water.1

Sidla ngokubhidaniswa no: The common name Irukandji jellyfish is also used for other Irukandji jellyfish, such as Malo kingi. The name alone does not tell them apart.1

Amandla etyhefu yokuluma nokuhlaba

Ii-tentacle ezihlabayo

Amawaka eeseli ezincinci ezihlabayo ziyadubula xa kukho into ezichukumisayo.

Ityhefu yaso yokuluma okanye yokuhlaba yenza ntoni?

This jellyfish is extremely venomous. Its venom comes from stinging cells called nematocysts in its tentacles and bell, and it changes as the jellyfish matures. A sting can cause Irukandji syndrome, with muscle aches, back pain, nausea, headaches, chest and stomach pains, sweating, high blood pressure and difficulty breathing.1

Siyingozi kangakanani ebantwini?

Irukandji syndrome can be severe, and the symptoms are described in detail in medical accounts. Most reported incidents have been in Australia during the warm summer season. Because the jellyfish is so small, people often do not see it before they are stung.1

Ukuba siyahlaba

  • In hospital, patients are given intravenous morphine, hydromorphone or fentanyl for pain. Pethidine is avoided because of its toxic metabolite norpethidine.1
  • Phuma emanzini kwaye ususe naziphi na ii-tentacle (ngeiglavu okanye ngelaphu).
  • Kwiijelifishi zebhokisi (box jellyfish) zasetropiki: thela iviniga kwiindawo ezihlatyiweyo ubuncinane imizuzwana engama-30, biza uncedo kwaye ulungele ukwenza i-CPR. Kwii-bluebottle nakwezinye ezininzi: hlambulula ngamanzi olwandle, emva koko usebenzise amanzi ashushu ngenxa yeentlungu.

Soloko utsalela inombolo kaxakeka kuqala (112, 000, 911). Esi sisikhokelo soncedo lokuqala ngokubanzi, asilocebiso lwezonyango. Iziseko zoncedo lokuqala

Hlala ukhuselekile

  • Ungaze uchukumise, ubambe okanye uqhule isilwanyana sasendle, nokuba sincinci, kwaye nokuba sibonakala silele okanye sifile.
  • Sinike indawo. Ukuba udibana naso, hlala uzolile, buyela umva kancinci kwaye usiyeke sihambe ngendlela yaso.
  • Ukuba siyakuhlaba: hlala uzolile, musa ukushukuma, tsalela inombolo kaxakeka (112, 000, 911) okanye uye esibhedlele ngokukhawuleza. Khumbula ukuba sasikhangeleka njani, ifoto iyanceda.

Asikuzingeli. Sisebenzisa ityhefu yaso ukubamba ukutya okanye ukuzikhusela, kwaye singakhetha ukuzimela. Okungakumbi malunga nokuhlala ukhuselekile

Iinyaniso

1

Jack Barnes of Cairns, Australia, discovered the species. During an exploration aimed at finding the cause of Irukandji syndrome, he allowed himself, a lifeguard and his 9-year-old son to be stung.1

2

Irukandji syndrome, which this jellyfish can cause, was first identified after a group of swimmers were stung in open water near North Queensland, Australia.1

3

Its venom changes in composition as the jellyfish grows, matching its change in prey from invertebrates to fish.1

4

Its life cycle alternates between a young form that attaches to a reef or rock and an adult form that swims freely in the water.1

5

This jellyfish is a type of box jellyfish, a group known for potent venom.1

Young jellyfish begin as a swimming planula larva, which settles on a reef or rock and grows into a polyp. The polyp later forms a colony that develops into an adult medusa.1
