Holosticha (whole-o-stike-a) (tentative identification) is a hypotrich ciliate in which the cirri are distributed in rows on the ventral surface. It is one of a large number of stichotrichine genera, and the genera can only be properly distinguished by careful mapping of the the distribution of the cirri - an exercise which requires special preparation of the cell. Differential interference contrast.

This species with endosymbiotic algae. Phase contrast.

This highly contractile marine ciliat has ventral cirri in oblique and marginal rows and three rows of dorsal cilia, thus it is a hypotrich structural grade. The adorale zone of membranelles shows clearly the assemblage of cilia to membranelles. There are very special dorsal cilia (visible as a lateral row), each of them emanate from a cortical papilla. Collected from Bodden, the brackish waters lying between the isles of Hiddensee and Ruegen (German Baltic Sea). This image was taken using Zeiss Universal with Olympus C7070 CCD camera.

Histriculus (his-trick-you-lus) is a hypotrich ciliate with cirri forming a row all around the margin and including across the back of the cell. Cell not flexible, by which it is distinguished from the very similar Oxytricha, also not with three long caudal cirri, by which it is distinguished from Stylonychia. With adoral zone of membranelles. Phase contrast.

These ciliates are undergoing conjugation, sexual exchange of genetic material.
