Cercomonas sp.2

Figs 3d , 4g –h

Description: Cercomonas . Cells are 8–12 µm and flexible with two flagella. The anterior flagellum is 0.25–0.5 times the cell length and beat from side to side, and its tip is thin. The second flagellum is about 0.5 times the cell length and appears to adhere to the cell body. Long strands of cytoplasm are seen from the posterior end of the cell.

Remarks: This organism is similar to Cercomonas sp. 1 in cell appearance and length, but can be distinguished by the shorter anterior flagellum and the presence of the posterior flagellum.
