Condylostoma (con-dee-lost-oh-ma) is a medium to large ciliate (usually over 100 microns long). Commonly associated with surfaces, and slightly enriched habitats. The large anterior mouth can pick up relatively large particles of food. It is a heterotrich ciliate, with conventional cilia over most of the body and used to propel the cell, but with larger cilia around the mouth. This cell has obviously been consuming a variety of algae. This Differential Interference Contrast (DIC = Nomarski) image shows the cilia of the Adoral Zone of Membranelles (AZM) around the front of the cell and leading to the mouth at the end of the groove slightly to the right of centre near the bottom of the picture.

Condylostoma vastum. Brightfield portrait of Condylostoma, a large heterotrich ciliate. The anterior is truncate, and the cell is tapered posteriorly. The posterior contractile vacuole is served by fine collecting canals which are difficult to visualize by light microscopy. There is a well-developed adoral zone of membranelles on the left margin of the V-shaped peristomal region and a large undulating membrane on the right margin, well seen here. This individual is consuming Trachelomonas. From a freshwater aquaculture pond near Boise, Idaho.
