ABSTRACT 



Approximately 3,000 reports of bioluminescent displays on 

 file at the U. S. Naval Oceanographic Office are charted by 

 three-month periods. In addition, various aspects of biolu- 

 minescence, bioluminescent organisms, seasonal and geo- 

 graphic distribution, and displays are discussed. A separate 

 chart and a discussion of the puzzling phenomena of the 

 "phosphorescent wheel" and "wave" displays are included.
