"Box jellyfish" or "sea wasp" is also a common name for the notoriously dangerous Chironex fleckeri. Box jellyfish are among the most venomous creatures in the world. Each tentacle has about 500,000 cnidocytes, harpoon-shaped needles that inject venom into the victim. Stings from these species are extremely painful and often fatal to humans and prey animals. Their venom can kill a human in a minute.
yes
Other species of jellyfish are among the most common and important jellyfish predators, some of which specialize in jellies. Other predators include tuna, shark, swordfish, sea turtles, and at least one species of Pacific salmon.

The most dangerous jellyfish are found off the coast of Brazil.The second most dangerous are found in the Great Reefs of Australia.Depending on what species of jelly you are, turtles, mola mola, sea birds, and other jellies prey on jellyfishes.Storms wash them up, climate changes can break or make cycles, marine debris can negatively contribute, but considering all that may, or may not be against them, jellyfish around the planet continue to thrive and in many cases are blooming faster than ever. There are many places that a major balance has taken hold, such as off Florida and the Gulf and others as well.
Coral Reefs don't really move and jellyfish move around, and sting people. Coral Reefs help other thins in the sea survive, where as jellyfish don't. The jellyfish are just there.
They do.
They swim around the ocen and use it for how all other animals use energy

It's big enough to inflict a good bite on a human, but the very fact that we thought they were extinct indicates how rarely we bump into each other. As compared to a shark or a jellyfish, no, a coelacanth is not dangerous.
no
No. The box jellyfish has a stronger poison than any other jellyfish.
in a short answer, yes. try looking on youtube for tangled jellyfish to see what I mean. and some jellyfish actually eat each other.
The box-jellyfish is special from all the other jelly-fish because, it doesn't drift but actually moves. All of the other jelly-fish just drift with the current, they are not moving. The box-jellyfish is actually not a jelly-fish. It is just called a jellyfish for its jellyfish appearance not for it truthfully being a jellyfish.
