Podophrya spec. hast trapped a Trichodina and is ingesting their cytoplasm. There ist no suction as the name "Suctoria" indicates misleadingly. An active membrane transport based on a microtubular system inside the tentacles is the engine of ingestion of the prey´s cytoplasm. The ingesting tentacles are widened. Collected from Bodden, the brackish waters lying between the isles of Hiddensee and Ruegen (German Baltic Sea). This image was taken using Zeiss Universal with Olympus C7070 CCD camera.
