The Irukanji jellyfishes (Carukia barnesi and the Malo kingi) are small, extremely venomous jellyfishes (Cubozoans, which are not true jellyfishes; Scyphozoans) that are found near Australia (not to be confused with the Sea Wasp or Box Jellyfish, which causes death and not Irukandji Syndrome). The Irukandji's sting causes symptoms which are collectively known as "Irukandji syndrome". They were first documented by Hugo Flecker in 1952 and named after the Irukandji people whose country stretches along the coastal strip north of Cairns, Queensland. The first-known of these jellyfishes, C. barnesi, was identified in 1964 by Dr. Jack Barnes; in order to prove it was the cause of Irukandji syndrome, he captured the tiny jelly and stung himself, his son, and a life guard.
