  • A demonstration using fluorescein dye illustrates the effectiveness of sponges in pumping water.
  • The experiment takes place on a Caribbean reef, showcasing the natural habitat of these organisms.

Observations from the Experiment

  • Within seconds, the dye is drawn through the sponges along with water, highlighting their role as effective water pumps.
  • Plankton entering with the water does not exit through the osculum, emphasizing their filtering capability.
