AUSTRALIA |
 Box jellies, also called sea wasps and marine stingers, live primarily in coastal waters off Northern Australia and throughout the Indo-Pacific |
 They feed on tiny fishes, marine worms like arrow worms and annelid worms, mantis shrimps, prawns, crustaceans, and sometimes they feed on the other box jellyfish. |

Several different species produce deadly venom in their stings. When left untreated, severe stings have even resulted in death. In Australia, researchers have recorded at least 64 deaths by the sea wasp in the past hundred-odd years.
The stinging cells of these creatures do not fire in response to touching an object. Instead, they react to the chemicals on the skin. This helps the creatures avoid wasting resources on inanimate objects.
Stings from some species, primarily Irukandji species, result in severe reactions. Some symptoms include anxiety, headache, vomiting, backache, chest pain, high blood pressure, and more.
