plankton

the organisms inhabiting the surface layer of a sea or lake, drifting with the current. Many planktonic organisms are capable of locomotion but are not sufficiently strong swimmers to move against the currents. Members of the plankton vary in size from unicellular organisms to large jellyfish, 1m or more in diameter. Compare NEKTON.
