Close up of somewhat flattened Paramecium caudatum, a ciliated protozoan, featuring the opening and closing of its contractile vacuole, an organelle similar to a pump, used to control the water level within protozoa. The green specks are algae cells the Paramecium has consumed. Recorded under Nomarski DIC with a horizontal field of view of approximately 150 microns. | |
