Stichotricha (stike-o-trike-a), un-named species. The body of the unidentified hypotrich ciliate has a broader posterior portion, and a narrowed anterior region. This is a detail of the cell surface showing the numerous long ectosymbiotic bacteria. Phase contrast.

Stichotricha (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 makes about one complete tour of the anterior part, winding down from the anterior to the cytostome located in the anterior part of the broader part of the cell. There are locomotor cirri over the body (not easily seen here), and also stiff projecting cilia / cirri. Some structures form a bracing structure to support the two very long cilia which extend 50 or 60 microns Phase contrast micrograph.

Stichotricha (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.

Stichotricha, hypotrich ciliate usually located in a flocculent mucoid mass adhering to submerged vegetation or other debris. The adoral zone of membranelles (AZM) is supported on a narrow and twisted anterior projection. Rows of cirri follow a curving path on the body.
