By Reuters Staff 2 Min Read March 17 (Reuters) - Australia’s surfing team have named themselves the Irukandjis after one of the deadliest species of jellyfish on the planet, as they seek to inject a bit of cold-blooded killer instinct into their preparations for this year’s Tokyo Olympics. The team settled on the world's smallest jellyfish, a native to the country's northern waters, because the tiny creatures pack a "serious punch", Surfing Australia chief executive, Chris Mater said in a statement here on Wednesday. The name Irukandji refers to several similar, extremely venomous species of box-jellyfish, which have an adult size of about a cubic centimetre, and actively hunt prey and fire stingers into their victims.
