Every different jellyfish has a different number of tentacles. The jellyfish mostly eats little tiny fish. They eat as the fish run into the jellyfishes tentacles or mouth. They catch fish by swimming up and then they stop and they sink to the bottom while catching the tiny fish while the fish are swimming around. The larger jellyfish mostly swim around freely.
Some jellyfish can glow in the bottom of the ocean.
Most jellyfish live close to land but some live on the bottom of the ocean. The enemies of a jellyfish are the sea turtle. The reason the jellyfish cant hurt the sea turtle is because it can't hurt the shell. The humans are also one of the enemies because they think that jellyfish are worst then they are and they kill the jellyfish. Ocean sunfish also eat the jellyfish.
