Carukia barnesi was created in 1967.
The Carukia barnesi jellyfish typically live for about 6 to 12 months in the wild. They have a short life span compared to other jellyfish species.

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.

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).
All jellyfish can sting.Box jellies are the most venomous marine animal known to mankind. Two species, commonly known as the Sea Wasp or Marine Stinger [Chironex Fleckeri] and the Irukandji [Carukia barnesi] are often fatal to humans. They are indigenous to Northern Australia, but show up occasionally in other Indo-Pacific areas, including Hawaii.Other sea jellies, such as the Portuguese Man of War and the Lion's Mane jellyfish can cause very painful stings, but rarely are life threatening. Most of the really common types (Moon, Comb, and Sea Nettle) have little to slightly annoying stings. Quite a few types do not even have stingers capable of penetrating human skin. Eyes can be a different story, however, so caution should always be used.
