Carukia barnesi(Irukandji) is a small box jellyfish about 25 mm across its bell. It has a single, retractile tentacle (50-500 mm long) attached at each of the four corners of its bell. The Irukandji is like other carybdeid jellyfish in that its nematocysts (stinging cells) cover not only its tentacles, but also its bell. The Irukandji’s venom is particularly potent and causes a set of symptoms known as ‘Irukandji Syndrome’ in humans. Very little is known about this small transparent jellyfish’s biology. So far it has been reported only from the tropical waters off Northern Australia.
