Plankton

(From the Ancient Greek planktos – drifting). The ensemble of aquatic organisms drifting on the surface of water flows, living in fresh, brackish or salt waters. They depend on vertical or horizontal currents to move about. We distinguish between three large plankton groups: phytoplankton, zooplankton and bacterioplankton (essentially composed of bacteria).
