The Irukandji is believed to be the most venomous creature in the world.


And if that’s not terrifying enough, this jellyfish only measures up to 2.5cm, making it extremely difficult to spot in open water. Although deadly, Irukandji are very fragile—you wont see them in standard aquariums, as the slightest impact against the glass would kill them.


You’ll mostly find them in Northern Queensland


The Irukandji gets its name from the Aboriginal tribe that inhabited North Queensland’s Palm Cove region, where Irukandji syndrome (produced by the Irukandji’s poison) occurs most often.


Getting treated for an Irukandji sting


Unlike a bluebottle, you can’t rely on vinegar or a warm shower to ease the sting from an Irukandji. If stung by an Irukandji jellyfish, your best bet is to head straight to the emergency room. Sting victims usually require painkillers and sometimes intravenous therapy, depending on the severity of the sting.


What is Irukandji syndrome?


The Irukandji’s sting causes symptoms collectively known as “Irukandji syndrome”. Initially, the sting feels quite mild, but can be followed by vomiting, profuse sweating, headache, agitation, rapid heart rate and increased blood pressure within minutes.


Doesn’t sound great, does it? So take precautionary measures.


If you’re travelling around the northern regions of Australia, note that this is Irukandji territory. Researchers have also stated that, due to global warming, Irukandji jellyfish may move south as the waters warm up. When swimming this summer, a lycra stinger suit will not only protect you from stingers, but from the sun as well. If you are going snorkelling or scuba diving, it is best to speak to a local expert about the water you’re swimming in.
