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

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

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

Bí o ṣe lè dá a mọ̀

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

A sábà máa ń ṣì í mọ̀ sí: 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

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

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

In hospital, patients are given intravenous morphine, hydromorphone or fentanyl for pain. Pethidine is avoided because of its toxic metabolite norpethidine.1

Òtítọ́

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
