Ciliate protozoan. Light micrograph of a freshwater ciliate protozoan (Stentor sp.). These are the largest protozoans found in freshwater. Some species reach 2 millimetres in length. They have a trumpet-shaped opening surrounded by a rim of cilia (not seen). The cilia beat to create a current of water that draws food,for example bacteria,inside.
