The Box Jellyfish or Chironex Fleckeri (best-known species)
Kingdom: Animalia
Phylum: Cnidaria
Class: Cubozoa
Order: Cubomedusae
The Box Jellyfish is one of the most deadly creatures in the world. They are called the box jellyfish because they have four distinct sides. Not all of their kind are lethal, but some are extremely venomous and can be lethal. Their venom is considered the most deadly in the animal kingdom. One would most likely die from the venomous sting unless they are treated immediately. The box jellyfish actually hunts its prey instead of just drifting and catching whatever they find. They are most abundant in Australia and the Indo-Pacific areas. They are usually one to three inches tall with tentacles as long as two feet. They can have up to fifteen tentacles.
They are very dangerous creatures and it would be wise to check the areas you are swimming in if you are vacationing in Australia or Hawaii.
