About Irukandji jellyfish :
The Irukandji Jellyfish scientific name is Carukia barnesi. They inhabits in the waters of Australia. They are very deadly jellyfish. The Irukandji is considered the most venomous creature.

Irukandji jellyfish usually eat small fish, crustaceans and marine invertebrates. They use their potent venom to kill their prey so that it does not run away. Venom is found in their stinging cells called nematocysts. Generally jellyfish have several types of nematocysts. The types of nematocysts are very helpful to identify some species
