Epistylis ciliate and rotifer. Light microscopy footage of an Epistylis ciliate protozoan with a rotifer inside its mouth. Epistylis is a genus of sessile single-celled protozoans, with a long stalk and a flattened head. At the top of the head is the mouth, surrounded by many fine cilia hairs. These create a vortex in the surrounding water, washing food particles into the mouth. Rotifers are microscopic aquatic animals that are related to roundworms. These specimens have been filmed in a sample of activated sludge, the term for a process that treats sewage and industrial waste water using bacteria and protozoa. This clip was filmed with darkfield illumination. | |
