Irricanji are jelly fish like creatures in the ocean around northern Australia. They are long and thin, about 1 cm in thickness.
If you get stung by one apparently it is like having sandpaper rubbed over your entire body, and this lasts up to 48 hours.
This is what I was told then I was in Cairns.
Irakanji is the smallest yet highly venomous jellyfish found in Australia only.
Their size is about one cubic centimeter which means it can slip through a jellyfish net net that protect people on the beaches of Australia from jellyfish.) Which make it highly dangerous, and what make it even more dangerous is that it has stingers on its bell (the head of a jellyfish.)
