Caption: Stentor. Light microscope footage of ciliate protozoan Stentor sp. feeding. Stentor species are filter-feeding freshwater protozoa which can reach lengths up to 2 millimetres. A ring of prominent cilia surrounds the anterior part of the cell to sweep in food and aid in swimming. The organism contracts suddenly at 32 seconds. Filmed with differential interference contrast illumination.
