Animal Species:Irukandji, Carukia-barnesi
This species is the first discovered of what appears to be a group of Carybdeid sea jellies whose sting causes what is now called Irukandji Syndrome. Transparent, small and usually not observed, the Irukandji is unusual as its bell also features stinging capsules (nematocysts).
1 cm - 2 cm bell (diameter), up to 1 m tentacles
Solitary and usually occupying deeper offshore waters of northern Australia from Western Australia to Queensland, the Irukandji is swept inshore by winds and currents year-round, more frequently in summer. Found rarely off Sydney and Melbourne.
