Euglenas are small algae. Most species have a whiplike flagella they use for locomotion. But these flagella are very difficult to see with brightfield microscopy. Contrast enhancing techniques like 'phase contrast' are needed.
The top species is Euglena Oxyuris, the bottom is Phacus longicauda. Note the red eye spots.
