Caption: Paramecium. Light microscope footage of ciliate protozoan Paramecium sp. The clip shows pulsation cycles of two contractile vacuoles (red rings). These act as osmotic regulators, actively expelling excess water out of the cell. Paramecium are abundant in water and soil. They move by the rhythmic beating of many hair-like cilia, feeding mainly on bacteria. Filmed with differential interference contrast illumination.
