Translucent jellyfish the size of a thumbnail can kill you

Irukandji jellyfishOtherwise known as “reasons for not immigrating to Australia”. The Irukandji jellyfish are among the world’s most toxic creatures, and being translucent and the size of a thumbnail, are nearly impossible to detect in the water. They used to be confined to Australia’s northern waters, but marine biologists are now finding them further and further south. Two deaths have been blamed on the jellyfish, and it’s likely that more will follow if they migrate into the tourist-filled waters along southern Queensland’s Gold Coast and Sunshine Coast holiday destinations.
