The smallest deadliest jellyfish is the Malo Kingi Jellyfish which is a type of Irukandji Jellyfish. It inhabits the waters of Northern Australia and is no larger than an adults fingernail making them impossible to see in the water. There are two types of Irukandji Jellyfish the Malo Kingi and the Carukia Barnesi. If these jellies don't kill you they will at least leave you with a nasty case of Irukandji syndrome which results in such symptoms as headaches, nausea, restlessness, sweating, vomiting, high heart rate and blood pressure, not to mention severe back pains, muscle cramps, kidney pains and an intense skin burning sensation.
