They are able to fire their stingers into their victim, causing a condition known as<unk>  syndrome, which can be fatal. There are about 16 known species of<unk> , of which Carukia barnesi, Malo kingi, Malo maxima, Malo filipina and Malo bella are the best-known. The<unk>  syndrome was named in 1952 by Hugo Flecker, who first described the symptoms of this<unk>  envenoming. The syndrome were named after the<unk>  people, whose country stretches along the coastal strip north of Cairns, Queensland. The first of these<unk> , Carukia barnesi, was identified in 1964 by Jack Barnes; to prove it was the cause of<unk>  syndrome, he captured the tiny<unk>  and allowed it to sting him, his nine-year-old son and a robust young lifeguard. They all became seriously ill, but survived. Australian toxicologist Jamie Seymour made a documentary about the<unk>  called Killer<unk> . In 2015, North Queensland researchers discovered evidence that<unk>  actively hunt prey.
