Cercomonas (sir-ko-moan-ass), gliding flagellates, two flagella insert just below the anterior apex of the cell. The anterior flagellum beats floppily, the posterior flagellum trails against the substrate. Body very flexible and elements may be drawn out as strands behind the moving cells. Common. Lots of species, but the taxonomy is very unstable. The very light region is the contractile vacuole. Phase contrast. This picture was taken by Linda Amaral Zettler, and David Patterson of material from the freshwater Lamont Pond (New York State, USA). Image copyright: L Amaral-Zettler and D. J.

Cercomonas

From the collection Lamont Pond, freshwater, New York

Description of Cercomonas: Gliding, with flexible body usually able to produce pseudopodia more often from posterior end, anterior flagellum varies in length from one species to another, it beats slowly and is flexible; posterior flagellum trails adhering in part to the ventral surface, usually lying in a groove. Some of the species (e.g., C. agilis ) may actively swim. Type species, C. longicauda Dujardin 1841.
