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
