An example of a single celled organism in the protist kingdom is the "Paramecium" or "slipper animalcule." The "Paramecium" moves using its small, hair-like fibers called cilia, and eats using the cilia to sweep the food into its food vacuole. Other protists can be amoebas, which move by extending pseudopods and flowing into them, or flowing around food particles and engulfing them.
