Tiny but Deadly, The Irukandji Jellyfish

Have you ever heard about Irukandji Jellyfish?

Irukandji jellyfish is known as small, invisible, deadly and extremely dangerous in Northen Australian waters.  This is deadly jellyfish which is only 1 to 16 inch in diameter with length about 1-3 feet,. There are two known species, Carukia Barnesi and Malo Kingi. 

The symptoms of Irukandji syndrome were first documented by Hugo Flecker in 1952. In 1964, Dr. Jack Barnes has identified Carukia Barnesi, the first known irukandji.

Irukandji has about 60 tentacles. Each tentacle could have 5000 sting cells (nematocyst) in the epidermis and have toxins that can kill 60 people. So, a Irukandji Jellyfish can kill approximately 3600 people.

Deadly Irukandji's venom can cause death, with symptoms: severe pains at various parts of the body (typically 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.
