• The box jellyfish (Chironex fleckeri) of northern Australia and Southeast Asia contains one of the most potent animal venoms known to man. A sting from one of these creatures can induce death in minutes from cessation of breathing, abnormal heart rhythms and profound low blood pressure (shock). The box jellyfish is also known as the sea wasp and the Australian box jellyfish (Source: DAN).
• The Irukandji jellyfish (Carukua barnesi) is a smaller relative of the sea wasp measuring only 0.6 in. (1.5 cm) to 1 in. (2.5 cm) across with four 20-inch (50 cm) tentacles. Irukandji has killed at least 70 people in the past 50 years. Chironex fleckeri has killed at least 100 people in the past century.
