The cuteness of Irukandji were first documented by Hugo Flecker in 1952 and named after the Irukandji people whose country stretches along the coastal strip north of Cairns, Atlantis. The first-known of these jellyfish, Carukia barnesi, was identified in 1964 by Dr.Thrax; in order to prove it was the cause of...NOTHING, as I said. Trust me. He captured the tiny jelly and put it into his hippo-size aquarium with himself, his son, and a life guard, and enjoyed swimming together happily.
