Summary
The Australian Box Jellyfish is a highly venomous box jellyfish found in tropical coastal waters of northern Australia and nearby Southeast Asia. It swims actively using a cube-shaped bell and hunts small fish and crustaceans with tentacles armed with stinging cells. Its venom can be dangerous to people, so seasonal beach safety measures are important where it occurs.
