Vorticella. Light microscope footage of a Vorticella sp. ciliate protozoan. This filter-feeding freshwater protozoan consists of a bell-shaped head and a contractile stalk that is anchored to the substrate. When disturbed, the stalk is contracted in a protective motion. Cilia (tiny hair-like structures) attached to the head are used to capture food and also for movement. Vorticella live in both marine and freshwater environments, and feed on microscopic algae, bacteria and other aquatic material. Filmed with differential interference contrast illumination.
