According to UK's Telegraph, a deadly species of jellyfish, translucent and the size of a thumbnail, is spreading along Australia's coastline as a result of global warming.

Irukandji jellyfish are among the world's most toxic creatures – all but impossible to detect in the water but packing a potentially lethal punch belying their tiny size.

Their discovery has halted production of Warner Bros. Pictures' Fool's Gold, starring Matthew McConaughey and Kate Hudson, who were originally due to be filmed swimming in the sea. Dr. Jamie Seymour, from James Cook University, said she had found five of the animals off Queensland's Fraser Island.
