Chlamydodon (clam-ee-doe-don), alga-eating hypostome ciliate. This cell was photographed immediately after dividing. During the division process, the cells do not eat. Food ingested before division is initiated is digested, with the rest that the cytoplasm is very empty and the major organelles can be seen with some clarity: orange zone, ingestion apparatus, macronucleus and railway track. Differential interference contrast.
