What are the known species of irukandji jellyfish?

Irukandji jellyfish are very tiny but extremely venomous jelly fish that are often found near the warm waters along the Queensland coast of Australia. The jelly fish is about the size of a fingernail but can release a potent toxin that can give one a big jolt. The Irukandji syndrome is named after the people who live along that North coastal strip of Queensland in Australia. Like other jelly fish, the Irukandji have stingers on both the tentacles and the bell. Once a human comes into contact with the jellyfish, the jellyfish injects a strong toxin which at first is not very painful. However, after a few minutes, the toxin does spread around the body and quickly exerts its effect. Not much is known about this obscure jellyfish partly because it is very tiny and fragile. It does not survive for long outside the water. The venom is known to stun small prĂªy. A single Irukandji jelly fish may not have much impact on an adult human, but multiple stings can have a profound effect. The typical

The Irukandji, a small jellyfish with a bell approximately 2cm in diameter is responsible for the unusual and dramatic syndrome observed following stings commonly known as Irukandji Syndrome. The Irukandji from its peanut sized body has a single retractile tentacle ranging from 50 to 500 mm long, hanging from each of the four corners of its bell. Unlike most other species of jellyfish all parts of the Irukandji can sting and not just the tentacles. The initial sting of the jellyfish is usually not very painful. However about 5 to 45 (in my case 10) minutes after being stung, the person starts to have a severe reaction, including backache, headache, shooting pains in their muscles, chest and abdomen. They may also feel nauseous, anxious, restless and begin vomiting. In rare cases the victim suffers pulmonary oedema (fluid on the lungs) which could be fatal if not treated or complete heart failure. How do we know about them? In 1964, a doctor called Jack Barnes spent several hours in a w

Irukandji jellyfish are tiny and extremely venomous jellyfish that are found mostly near Australia, and which cause symptoms collectively known as Irukandji syndrome. Its size is roughly no larger than a fingernail of an adult’s little finger. There are two known species, Carukia barnesi and the recently discovered Malo kingi. The symptoms of Irukandji syndrome were first documented by Hugo Flecker in 1952 and named after the Irukandji people whose country stretches along the coastal strip north of Cairns, Queensland. The first-known of these jellyfish, Carukia barnesi, was identified in 1964 by Dr. Jack Barnes; in order to prove it was the cause of Irukandji syndrome, he captured the tiny jelly and stung himself, his son, and a life guard.
