Ciliophrys (silly-off-rees), a pedinellid stramenopile, with a single flagellum. The cell may exist as a non-swimming form with radiating arms, and with the flagellum inactive or beating in a languid figure of 8 motion. The arms can be resorbed, and the cell can then swim with the flagellum pulling the cell forward. This is the heliozoon form, with a nucleus in the centre of the cell. Phase contrast.

Ciliophrys (silly-off-riss) infusionum Cienkowski, 1876. Helioflagellate, in the heliozoan stage the cells are about 4 - 9 microns across, and have a central nucleus and one flagellum held in a figure of eight. The cells are spherical with delicate pseudopodia extending radially from the body and bearing extrusomes. The cells may change from the heliozoan stage with pseudopodia and a slow beating flagellum to a swimming flagellate without pseudopodia and with the flagellum beating rapidly. In swimming cells, the nucleus is located apically. Observed to consume suspended bacteria. When feeding, bacteria adhere to the pseudopodia and then are drawn to the body. The cells eat diatoms up to 18 microns long. Sometimes common.

Portrait of Ciliophrys infusionum (Cienkowski,1876), one of the colourless pedinellid flagellates (also referred to as a helioflagellate). When at rest on the substrate tentacles(axopodia supported by one triplet of microtubules) of with fine granules are distributed over the entire surface and the single flagellum is held in a tight S configuration hardly moving. When swimming, tentacles withdraw and the cell surface appears smooth, the flagellum beating more rapidly in sine wave fashion. From standing freshwater near Boise, Idaho. Phase contrast.
