Irukandji jellyfish

Irukandji jellyfish are small and extremely venomous jellyfish that inhabit marine waters of Australia. But according to a National Geographic documentary on jellyfish the species has been found in waters as far north as the British Isles, Japan, and the Floridacoast of the United States. They are able to fire their stingers into their victim, causing symptoms collectively known as Irukandji syndrome. The Irukandji syndrome is produced by a small amount of venom and induces excruciating muscle cramps in the arms and legs, severe pain in the back and kidneys, a burning sensation of the skin and face, headaches, nausea, restlessness, sweating, vomiting, an increase in heart rate and blood pressure, and psychological phenomena such as the feeling of impending doom. The symptoms last from hours to weeks, and victims usually require hospitalisation. The size of the Irukandji jellyfish is roughly a cubic centimetre (1 cm3). There are 4 known species of Irukandji. photo credits: wikipedia, deadlylist, life-sea
