Portrait of Cyclidiopsis acus (Korschikoff, 1917), a colorless euglenoid flagellate. Similar in general morphology to Euglena acus but without plastids. Flexible but not metabolic. Swims or glides slowly. One short emergent flagellum less than one quarter body length. The pale orange stigma is visible here at the junction of the anterior apical canal and the reservoir. The contractile vacuole is posterior to the reservoir. Multiple long, needle-shaped paramylon bodies are visible in the cytoplasm. From standing freshwater. Boise, Idaho.June 2005.DIC.
