Lisa-Ann Gershwin is a biologist based in Launceston, Tasmania, who has described over 200 species of jellyfish, and developed a system to predict blooms of the hazardous Irukandji jellyfish in north Queensland. She led a team that discovered that the blooms coincide with the blooming of salps, and that these were prompted by upwelling after the dying down of trade winds. She has described several poisonous jellyfish—nine species of irukandji, including the Queensland species Malo kingi and Malo maximus, and the giant irukandji species Keesingia gigas from Western Australia, which was discovered without tentacles.
