Summary
Shows and discusses plant and animal plankton which sustain life in the sea.  Points out that these organism may vary in size from microscopic to quite large.  Uses film sequences of jellyfish to show variations in size, shape, and swimming habits. Explains how many seashore animals spend their larval or juvenile phases as members of the plankton.  Depicts this phenomena with motion pictures of larval crabs as they gather around a night light suspended in water from a pier.  Concludes with an explanation of microplankton which constitute the great pasturage of the sea.  Demonstrates methods used in collecting microplankton, shows them under the microscope, and considers the necessity of more knowledge and understanding of plankton. (KCTS) Kinescope.
