Metanema (met-a-knee-ma) strenuum (Skuja, 1948) Larsen, 1987. 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 moves 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. Rarely observed. This picture was taken by Won Je Lee using conventional photographic film using a Zeiss Axiophot microscope of material collected in marine sediments of Botany Bay (Sydney, Australia). The image description refers to material from Botany Bay. Image copyright: Won Je Lee, image used under license to MBL (micro*scope).
