Microscopic image of a flagellate, a long oval with a long, thin tail extending out and away from one end.

The three types of protists are distinguished by their method of locomotion: flagellates (use a whiplike flagellum), amoebas (use a pseudopod), and ciliates (use short "hair"). Microphotography provides a close-up examination of flagellates and amoebas, noting their similarities, differences, and some examples of the huge numbers of species.
