Northern Australia

The coast of Northern Australia serves as a home to chironex fleckeri, also known as the box jellyfish, which has caused 60 deaths in the last 100 years, according the Center for Disease Control, Australia.

While fatalities are rare, about 40 people are hospitalized each year in the Northern Territory. Last year, a 6-year-old boy died in the Tiwi Islands, north of Darwin.
