Stentor ciliate protozoa. Fluorescence light micrograph of Stentor polymorphus ciliate protozoa. These ciliate protozoa inhabit freshwater, where they feed mainly on bacteria. They move by beating their cilia, hair-like extensions that cover their bodies. The small red bodies inside the protozoa are individual Zoochlorella sp. algae, which have a symbiotic relationship with the protozoa. They photosynthesise inside the Stentor, providing it with sugars and oxygen, while deriving protection from their host. Magnification: x114 when printed at 10 centimetres wide.
