[1] In Australia, it is known from the northern coasts from Exmouth to Agnes Water, but its full distribution outside Australia has not been properly identified. This treatment is no longer recommended by health authorities,[14] due to research which showed that using bandages to achieve tissue compression provoked nematocyst discharge. The sting can produce an excruciating pain accompanied by an intense burning sensation, like being branded with a red hot iron.

The venom of C. fleckeri contains a variety of bioactive proteins that are cytolytic, cytotoxic, inflammatory or lethal, however, few individual venom proteins have been thoroughly characterised and their mechanism(s) of action remain unclear. The egg and sperm haploid forms of the Chironex fleckeri life cycle are called gametes. It produces potent and rapid-acting venom and its sting causes severe localized and systemic effects that are potentially life-threatening. [10] Among 225 analyzed C. fleckeri stings in Australia's Top End from 1991 to 2004, only 8% required hospital admission, 5% received antivenom and there was a single fatality (a 3-year-old child). Trouvez les Chironex Fleckeri images et les photos d’actualités parfaites sur Getty Images. Also, the researchers did not determine whether the increase in venom concentration was caused by already-discharged nematocysts releasing more venom, or if the venom that was released initially had simply leaked back out through the membrane, thus confounding the concentration measurement.
