Irukandji Jellyfish - World's deadliest fishing

The Irukandji jellyfish, fish for fish using deadly extendable arms that are covered in venomous stinging cells. As it swims along, this tiny jelly extends its tentacles and twitches them much like a fisher or fly-fisher would to attract prey in the water. The balls of venomous stinging cells (nematocysts) act like a lure and attract fish. When contact is made with the tentacles the venomous harpoons are fired into the prey which paralyses them.

This is the most Aussie thing ever. "I've been stung eleven times and each time I ended up in hospital" . . . if I'd been stung twice, you wouldn't get me back to the beach.

What's particularly interesting about these guys is that Irukandji syndrome is almost certainly an unintended side effect from the jellies' point of view. It's useless for hunting OR meaningful defense...the onset is simply too slow. It's something in our bodies reacting in some very strange and potentially catastrophic ways to a venom that is otherwise quite mild.

We can create body armor that can stop rifle rounds, but why cant we create a body suit to protect against jellyfish stings?

@LeatherCladVegan 6 жыл бұрын

We can (if that's even a serious question). Of course we can. We can build tank armour that stops 155mm High-explosive anti-tank rounds. We can create chain-mail wet-suits that defend the wearer from shark bites. The problem is that we can't yet make them practical, and even if we could, we would not be able to make them affordable, as that would require many people to buy them, and most people want to enjoy swimming freely without wearing chain-mail and a full wet-suit. Technology like graphene, carbon nanotubes, etc, might change that one day... We'll see.

Wouldn't the Irukandji be more potent than the Chironex if it was the same size as it's cousin? Since a tiny sting from a Fleckeri only causes scarring, but no hospital or long-lasting symptoms like the Irukandji?

@GaldirEonai 6 жыл бұрын

The thing about the Irukandji-Syndrome-causing box jellies is that their venom is _initially_ quite mild. Many victims don't even notice the initial sting. It's just that an hour or two _after_ the sting, through a mechanism that isn't fully understood yet, the secondary effects kick off, and they're _evil_. Meanwhile, with a Chironex sting you _definitely_ know that you've been stung, and the effect is very, very rapid. Many fatalities occur when victims suffer from circulatory collapse or heavy cramping while still trying to get back to shore and simply drown.

@brickx4106 6 жыл бұрын

The Australian Box Jellyfish Chironex Fleckeri known as the (Sea Wasp) is the deadliest creature on our Planet. Chironexs can kill you in 2 minutes. The Australian Box Jellyfish Irukandji is the 2nd deadliest creature on our Planet. After getting stung by Irukandji (painless, or mosquito bite sensation) it take 15-30 minutes for the venom to reach thru your Lymphatic system (lymphs nodes) will the painful effects kick in, also in some cases Irukandji Jellyfish can cause Irukandji Syndrome which is unique and devastating on the human body. Irukandji syndrome can last for days, months even years.

@brickx4106 3 жыл бұрын

If Irukandji were the size of Chironexs the moment your stung you die instantly. Then Irukandji would be the most lethal.
