Box jellyfish have transparent and pale blue which makes it invisible in the ocean.
For many years people did not know what was injuring or killing people.
It moves by shooting it's self forward like a jet and it moves 2 meters per second.
The box jellyfish has eyes which other jellyfish do not. They have eyes on each side of their box like sides and scientist don't even know how they see because they don't have a central nervous system.
They live off of northern Australia, near new Guiana, Philippines, and Vietnam.
They like to hang around River mouths and creeks. They lay their eggs at the river mouth and when they hatch they are called polyps which they stay on rocks until spring. Then they go into the ocean.
Box jellyfish eat small fish and crustaceans
The box jellyfish's top is so soft that the things that it try's to eat will most likely tear it apart so it has to sting it really fast.
The stinger has not only one type of venom but three. One called cardio toxic venom which effects the heart. Second one is neurotoxic venom which damages the nerves. The last one is dermatonecrotic which melts the skin.
If at least three meters of a tentacle touches you it can be fatal.
If not the victim will most likely go into cardiac arrest in minutes. If that does not happen the sting is so over whelming the victim can also go into shock.
The only treatment of the sting is vinegar and there is no cure.
The sting is usually not the reason why people die to it. It is mostly people drowning because of the shock you go into
