because scientists did not know before and they thought that they were fish so they decided to call it like that.
Most if not all jellyfish are carnivorous.Jellyfish are carnivorous, eating plankton, crustaceans, fish eggs, small fish and other jellyfish.
Yes, they do all the time, even though jellyfish do not have brains, their stinging tentacles are near invisible in water. Unsuspecting fish swim into these tentacles and are paralyzed by the stinging cells that the jellyfish contains which affect the nervous system. The fish is then drawn into the 'head' of the jellyfish and digested.
Fish are vertebrates, jellyfish are invertebrates.
Jellyfish eat a large variety of things including small plants, copepods, fish larvae, fish eggs, plankton eggs and even other jellyfish. Several of these are producers.

jellyfish is not a fish.
jellyfish eat small fish and microplankton
Jellyfish, reptiles, and fish are all members of the animal kingdom.
jellyfishes eat plankton fish and even feed on other jellyfishes
Jellyfish will prey on other jellyfish, shrimp, fish, and fish eggs. They will eat animal that drifts in to their tentacles.
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.
