Description of Hexamita inflata: Cells are roundish to ovoid and about 6 - 10 microns long. Several contractile vacuoles are seen. The posterior end of the cell may be pointed or rounded. Two nuclei are located anteriorly, and two longitudinal cytostomal tubes are visible below the equator of the cell and on the ventral side of the cell. There are two sets of 4 flagella (total eight flagella); two medium flagella are about 1.3 - 1.5 times the cell length, four short flagella are about the cell length. These flagella insert anterio-laterally into a small depression on the anterior part of the cell. Two long flagella emerge from the cytostomal tube and are about 2 times the length of the cell. The long flagella normally cross each other. The cells move by skidding or swimming.
