Box jellyfish have a square-shaped float with tentacles streaming from the corners of the bell. Jellyfish sting using nematocysts. Nematocysts are tiny stinging cells. When an animal brushes up against a box jellyfish, the nematocyst cells puncture the victim and lets out a deadly venom. The venom kills the animal. These animals are usually invertebrates. Some box jellyfish venoms can be deadly to humans.

There are 28 species and three of them can kill a human. They live in the Gulf of Mexico, Japan and Australia. The sea wasp possesses the most potent venom of any marine creature. The venom attacks the heart and its victim can die in minutes. The sea wasp can “swim” at a rate of 3 mph. A sea wasp can grow up to be the size of a basketball. It can have up to 15 tentacles, each that measure about 3 meters long. The sea wasp also has 3 eyes. Two eyes detect only light. The third eye is somewhat like ours. It can form images.

On March 23, 2003, a seven year-old boy was swimming on an unprotected beach near Cairns, Australia. Suddenly he began screaming in pain. His grandfather rushed into the water and pulled the boy out of the water. After 10 minutes the child suffered full cardiac arrest. This boy was the 68th person to die from a sea wasp since 1883.
