Irukandji jellyfish
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

Indlela yokusibona
- 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
Ivamise ukudidaniswa ne: 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 obuthi
Izinkulungwane zamaseli amancane ahlabayo ziyadubula uma kukhona okuzithintayo.
Ubuthi baso benzani?
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?
Ingozi ebantwini: Kuyingozi kakhuluSingabulala umuntu ongatholi kwelashwa.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
Uma sihlaba
- In hospital, patients are given intravenous morphine, hydromorphone or fentanyl for pain. Pethidine is avoided because of its toxic metabolite norpethidine.1
- Phuma emanzini bese ukhipha noma yimiphi imicu ehlabayo (ama-tentacle) (ngamagilavu noma ngendwangu).
- Kuma-box jellyfish asezindaweni ezishisayo: thela uviniga ezindaweni ezihlatshiwe okungenani imizuzwana engama-30, biza usizo futhi ulungele ukwenza i-CPR. Kuma-bluebottle nakwamanye amaningi: hlanza ngamanzi olwandle, bese usebenzisa amanzi ashisayo ngenxa yobuhlungu.
Njalo shayela kuqala inombolo yezimo eziphuthumayo (112, 000, 911). Lokhu kuyiseluleko sosizo lokuqala esijwayelekile, akusona iseluleko sezokwelapha. Izisekelo zosizo lokuqala
Hlala uphephile
- Ungalokothi uthinte, ubambe noma ugcone isilwane sasendle, ngisho noma sincane, futhi ngisho noma sibukeka silele noma sifile.
- Sinike isikhala. Uma uhlangana naso, hlala uzolile, uhlehle kancane bese usiyeka sihambe ngendlela yaso.
- Uma sikuhlaba: hlala uzolile, ungashukumi, shayela inombolo yezimo eziphuthumayo (112, 000, 911) noma uye esibhedlela ngokushesha. Khumbula ukuthi besibukeka kanjani, isithombe siyasiza.
Asikuzingeli wena. Sisebenzisa ubuthi baso ukuze sibambe ukudla noma ukuzivikela, futhi singancamela ukucasha. Okwengeziwe mayelana nokuhlala uphephile
Kuphi emhlabeni?

Yizibalo nje kusiphequluli sakho. Akukho okulondolozwayo noma okuthunyelwa ndawo.
Sishesha kangakanani?
Amaqiniso
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
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
Its venom changes in composition as the jellyfish grows, matching its change in prey from invertebrates to fish.1
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
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
