(stike-o-trike-a), un-named species. The body of the unidentified hypotrich ciliate has a broader posterior portion, and a narrowed anterior region. The adoral zone of membranelles can be seen to the right of the anterior-most part of the cell and then to the left near the cytostome located in the anterior part of the broader part of the cell - showing that it makes about one complete turn around the body. There is a sheath of material (ectosymbiotic bacteria?) which supports the caudal cilia. Differential interference contrast.
