Irukandji Syndrome

wiki Irukandji syndrome is a condition induced by envenomization through the sting of Carukia barnesi, the Irukandji jellyfish, and other cubozoans.[1] It is seldom fatal, but is nevertheless one of the most painful experiences a human can experience. The condition was given its name in 1952 by Hugo Flecker, after the Aboriginal Irukandji people who live in Palm Cove, north of Cairns, where stings are common.

Fucking scary.
