Scientific names: Carukia
barnesi, Malo kingi and discovered in the 2000s and 2010s, Malo maximus, Malo

This deadly jellyfish is known as the Irukadnji. As noted above, there are
five species of Irukandji with unique scientific names but they all share the
same venom that will leave the victim a compilation
of general symptoms which include severe headache, backache, muscle pains, chest and abdominal pain, nausea, sweating, anxiety, hypertension, tachycardia, and pulmonary edema. These venomous box jellyfish are roughly the size of a dime and unlike most jellyfish, the Irukandji also have nematocysts on its bell. If you are swimming during wet and summer seasons in Australia, and slightly felt a tingle or a faint mosquito bite, then quickly address it.
