They then develop into polyps, which attach themselves to the sea floor, where they feed and grow and produce other polyps, in much the same way as a bromeliad produces offspring. As food supplies come along then the nutrients are distributed to all of the polyps through those feeding tubes. Evidently something is out of balance, but, as many species suffer, the jellyfish prospers. The Box Jellyfish has been given the nickname of the Sucker Punch Jellyfish.
