Box Jellyfish

box jellyfish, (class Cubozoa), also called sea wasp or cubozoan, any cnidarian (or coelenterate) belonging to the class Cubozoa. The class is made up of approximately 50 species, which are known for their semitransparent box-shaped bell and the toxic venom produced by some species. Box jellyfish live in warm coastal marine waters around the world, and species with toxic venom are generally found in the Indian and Pacific Oceans, between Thailand and the Philippines and off the coast of northern Australia. The deadliest species, as well as the largest species, is Chironex fleckeri, the Australian box jellyfish, which is found in the waters along Australia’s northern coast.
