Dexiotricha granulosa, annotated

Dexiotricha granulosa is a scuticociliate, 50-70 μm long, whose cytoplasm is packed with tiny ring-shaped glyocogen granules. The cell has a distinctive pattern of kinetids at the anterior (which looks to me, like the winding path around a tiny mountain). These are not true ciliary rows or kineties (I mislabelled them as such, in the original video) but "paratenes", which appear as transverse rows running at right angles to the longitudinal kineties (see Denis Lynn, The Ciliated Protozoa, 2008, p. 43). Contractile vacuole and macronucleus are close together, at the midpoint of the cell.
