The Limits of Pain - Irukandji Syndrome




"I didn't think it was possible for anyone to endure that level of pain
without turning into a vegetable..."

-Irukandji victim


Great Barrier Reef, northern Australia. Enveloping thousands of kilometers of the Queensland coastline, the largest reef in the world attracts tourists in their millions every year to marvel at the incredible coral features, miles of unspoilt beaches, and to snorkel and scuba dive in its lazuline waters.

But any visit to the shore of Queensland brings unrelenting reminders that this idyll comes with a price. During the peak of its high season between december and january, many tourists are surprised to find endless beaches closed, dotted with vague warning signs. A return to the popular seaside resorts finds tiny portions of beach equipped with buoyed net enclosures, a half-hearted compromise for intrepid bathers in a season where the sea itself has become a threat.






Beyond the delicate mesh of the nets, the sea wasps have arrived. Jellyfish, of all shapes and sizes, are drawn to the shallow waters near the coast where their prey of small fish is plentiful and more easily caught.

Infamous among them and seen to the left is the lethal Box jellyfish, chironex fleckeri, considered to be one of the most venomous creatures on earth. Its powerful sting gives instant and excruciating pain, affecting the heart and nervous system in ways capable of killing an adult human in a matter of minutes. Survivors are often left with horrible scarring as if severely burned.


The stinger nets turned out to be a crude but effective solution against the chironex fleckeri. Because it often grows as big as a human head, the mesh would easily keep it, along with sharks and other marine predators, from coming in contact with the swimmers within. Tourists could feel safe, and injuries were largely prevented.



That is, until reports started coming in of a whole new set of symptoms. Rumors told of a sting that was hardly even felt, that left no mark on the skin, and that, 20 minutes later, started its sinister effect on the body with overpowering nausea. And then pain. Unimaginable, unwavering pain. Pain so severe, the mere sustained shock of it could prove fatal.

Something was slipping through the fine mesh of the protective nets, and it would take years of detective work to track down the tiny, invisible creature behind the new attacks. Heart attacks and similar conditions were often blamed in the case of tourists; in scuba divers, decompression sickness was suspected. When the news finally broke, the unassuming, anonymous nature of the elusive culprit only added to the terror.




Carukia barnesi - the ancient Irukandji jellyfish. The size of a man's thumbnail with four tentacles only a few inches long, it is effectively transparent and impossible to see or avoid. Its venom is 100 times as potent as a cobra's, and only the minuscule amount injected in each sting keeps the jellyfish from being the top killer of the Queensland shore. But in a diabolical twist, while its venom might be unlikely to kill outright, it has been known to make its victims long for the respite of death as an end to its unbearable pain.





“The symptoms overwhelm you. On a pain scale of 1 to 10,
it rated between 15 and 20...”

- Irukandji victim


It is likely that the pain from an Irukandji sting ranks among the most intense and excruciating agonies possible to experience - skirting the actual limits of maximum pain. With the soaring blood pressure, profuse sweating and frantic cramps, some bodies simply buckle under the pressure of the unrelenting torment, with brain hemorrhages and heart attacks having been documented as a result. Victims report wanting to rip their own skin off, begging doctors to be killed just to be put out of their misery. A female victim elaborates, "It's like when you're in labor, having a baby, and you've reached the peak of a contraction—that absolute peak—and you feel like you just can't do it anymore. That's the minimum that [Irukandji] pain is at, and it just builds from there."




"I don't think anything can prepare you for it. It comes in these sorts of crazy waves of pain, which increase in intensity
until you get to the point where you just can’t handle it..."

- Irukandji victim



Dr Peter Fenner is Australia's leading expert on the grouping of symptoms that later came to be known as Irukandji syndrome. What he tells of the course of the symptoms shows that the Irukandji has further tricks up its sleeve than the mere pain: "You get cramping in the muscles of the legs, moving up into the abdomen, into the chest, into the arms," says Dr Fenner. "It's the really severe cramping pains that people become totally distraught by. It comes in waves, rather like labour pain, getting stronger and stronger. You need vast doses of morphine to control the pain. Victims get a really severe headache and begin vomiting. They feel absolutely dreadful. A feeling of impending doom is how they describe it".

Disturbingly, Irukandji venom seems to affect the mind as well. Victims report a sense of being certain that the pain will kill them, that death is inevitable, compounding the overwhelming stress of the experience. No antivenom exists, and in some cases not even the strongest painkillers can take the edge off the torturous suffering. Because Irukandji syndrome, though temporary and rarely lasting longer than a few days, has such a varied and unpredictable progression, complete sedation is extremely risky, leaving no other course for victims than be left alone to face the onslaught head-on, writhing in torment at the limits of pain.

  2. This toxin's potential as some kind of bioweapon is terrifying. And I'm not saying that from the POV of an advocate, but from the POV of a reader who has just had the living **** scared out of him.

  5. Hy. I really like your entries. I think it is fantastic, that you dont give your own oppinion about these things, rather let the readers decide what they think. It's awesome journalism. No useless doublespeak, just the essence of the topic. But I would like to also add a suggestion. When you use a latin name, the first name begins always with a capital letter, so it is Chironex fleckeri. It's not a big deal, but scientificaly it is appropriate this way.

    Keep up the good work!

  6. I don't know much about bioweapons, but as long as I know animal toxins aren't the main components of them. Rather they contain toxins of bacteria, like anthrax, which can be inhaled. You see, this toxin, and also the venoms of snakes, mollucs, octopuses, and so on, must be entered into the blood vessels to be effective. Snake venoms for instance, cause much less trouble if ingested, in case they not go into the blood vessels, via micro injuries in the mouth. In case of venoms of vertebrates, and I think in this case too, venoms consist of proteins. These are vulnerable to UV light, and heat. If they are not well kept, or not frozen, they can loss their toxic nature, so I think it would be difficult to make bioweapons, from this, but who knows?

  17. i saw this on one of the science channels. this young blonde woman who was researching box jellies got stung . later they showed her squirming around in agony on a hospital bed it was crazy. she was like kicking her legs around all over the bed and moaning and rubbing her face and her body. . they said she was writhing around like that for 18 hours straight and it took her 2 weeks to fully recover... afterwarrds she said she felt like she was being stabbed and her limbs and head were being crushed a vice and her skin felt like it was on fire. crazy!

  18. About ten years ago while working in a hospital i saw the most horrific sight . A group of girls, i think college age, all from Brazil, had come here and i guess didn't know much about box jellies or stinger suits. All 7 of them were swimming in irukandji infested waters in just their bikinis and all 7 of them got stung multiple times. i've never seen such suffering. when i first saw them, they were laying on the floor of the emergency room waiting area where they had collapsed after being brought in. the screaming and moaning filled the halls and you could hear them from the second floor. There were lying there, on the floor piled around each other, writhing in pain, still in their swimsuits and soaked with sweat. I remember at least three of the girls were violently bucking, thrashing and kicking their legs around like they were being drowned in acid. i remember being unsettled by how the girls legs and bodies writhed around against each other and yet they were completely oblivious of their surroundings or even each other. you could see it on their faces, they were literally in their own world of suffering. after we got them onto beds (some of them had to be strapped down), they writhing and screaming continued for hours. Two of the girls were at it for almost two days, squirming and moaning almost nonstop. One of the girls we had to tie down begged for us to kill her. It was so awful. I'll never forget that day.
