RESEARCHERS have discovered three new species of irukandji jellyfish and developed a world-first breeding program for the creatures - breakthroughs being hailed as important steps towards developing an antivenom to treat the animal's often lethal stings.
One of the three new jellyfish species discovered this month off the coast of Broome, in Western Australia's remote Kimberley region, has been described as one of the world's most poisonous creatures.
Of the other new species, one is not generally fatal and the other's toxicity is not yet known.
The poisonous new species - which is transparent and has 12mm bell-shaped bodies - most closely resembles the irukandji species that killed British tourist Richard Jordan, 58, in the Whitsundays in January 2002 and American tourist Robert King, 44, off Port Douglas in April 2002.
