Description of Metanema strenuum: Cells are ovate, about 22 to 27 microns long, flexible, and flattened. There is a knob near the base of the posterior flagellum. The cell has a small posterior protuberance. There are about 24 very distinct striations on each face of the cell. The cells move with a skidding action with the anterior flagellum directed towards the right and the posterior one to the left. Both flagella are slightly longer than the cell. The nucleus and reservoir are in the left side of the cell. The ingestion organelle is not visible.
