Irukandji Jellyfish

• The Irukandji is a very small jelly, but is still extremely venomous!
• When first found by the scientist Dr. Jack Barnes in 1964, in order to prove that the fish was venoumous and causing the Irukandji syndrom that many people were falling sick from, he stung himself, the lifeguard and his son.  All became very sick from the syndrome (but lived).
• These tiny creatures have been found all over the world and can cause symptoms including extreme muscle cramping and pain, nausea, headaches, and increased blood pressure!
