Carukia barnesi is a small and extremely venomous jellyfish found near Australia. Stings can result in Irukandji syndrome, and thus this species is commonly known as Irukandji jellyfish, although this name does not distinguish it from other Irukandji jellyfish such as Malo kingi.
A mature C. barnesi's bell is only 12 mm by 30 mm in height. It has four contractile tentacles, one extending from each bottom "corner" of its bell, ranging in length from 50mm to 500mm.[1] The jellyfish was discovered by, and named after, Jack Barnes.
