Quote from Wikipedia: "Irukandji syndrome is a condition induced by envenomization through the sting of Carukia barnesi, the Irukandji jellyfish, and other cubozoans.[1]"Note: Irukandji Syndrome has nothing to do with Down Syndrome and this question should NOT be placed in the Down Syndrome category!
The most poisonous species of jellyfish are said to be Chironex fleckeri and Carukia barnesi, both Cubozoa.Carukia barnesi is the IrukandjiThe most poisonous type of jellyfish is the ''box jellyfish''. Getting stung from this type of jellyfish will usually cause death in around 180 seconds.Some species of box jellyfish produce extremely potent venom: Chironex fleckeri, Carukia barnesi and Malo kingi are among the most venomous creatures in the world. Stings from these and a few other species in the class are extremely painful and can be fatal to humans.There are hundreds of species of poisonous jellyfish in the world. One of these very famous poisonous jellyfish is the box jellyfish.

I found an article that states box jellyfish rarely live past a year in the wild and in that time can grow to 10 feet and to a weight of 4.4 pounds. There are nineteen species of box jellyfish. Some are quite large such as Chironex fleckeri described above. One variety is very small, Carukia barnesi which less than an inch in girth, and weighing less than an ounce.

The three most poisonous jellyfish are the box jellyfish (Chironex fleckeri), the Irukandji jellyfish (Carukia barnesi), and the Portuguese man o' war (Physalia physalis). The box jellyfish is known for its potent venom that can cause heart failure and death within minutes. The Irukandji jellyfish, though small, can cause severe pain and potentially life-threatening symptoms known as Irukandji syndrome. The Portuguese man o' war, while not a true jellyfish, possesses a venomous tentacle that can deliver painful stings and allergic reactions.
No. (please read sub-answer)No, but it is one of them. The most infamous one in the world is the Chironex fleckeri, whose venom in their entire body is enough to kill 60 humans. If a sting from the Chironex fleckeri is untreated, the victim can also die in as little as three minutes.
The most dangerous species of jellyfish are Chironex fleckeri and Carukia barnesi, both belonging to the Class Cubozoa (box jellies).
