The authors' investigations of infusorians as a component of the planktonic community in the Baltic Sea coincided with the heterotrophic stage of seasonal succession, and as a result the infusorians were numerous. In the deep troughs of the Sea at a depth of more than 150 m, the water is saturated with hydrogen sulfide. A community of infusorians relating to the saprobionts and capable of living with the minimal amount of oxygen was discovered for the first time--in the upper boundary of the hydrogen sulfide zone. In its level of infusorian abundance, the Baltic Sea must be considered a eutrophic body of water where infusorians serve as one of the leading agents in its self-purification.
