Description of Peranema trichophorum
Cells are metabolic and 35 to 50 microns long, have longitudinal pellicular striations around the cell. The anterior end of the cell is slightly pointed and the posterior end is truncated, rounded, or indented. This body is slightly curved and the flagellar pocket is also to the right. The flagellar pocket including the flagellar canal is up to 40 % the length of the cell. The anterior flagellum is as long as the cell, is thick and is directed forward when the cell is moving. The posterior flagellum may be hard to observe, is thin, and tightly adpressed to the cell surface, lying in a narrow longitudinal groove. The ingestion organelle has two rods and is weakly developed. The nucleus is posterior to the centre of the cell. The cells glide in contact with the substratum.
