Paramecium are oval-shaped, have two nuclei (one large and another small), and has cilia unlike amoeba and euglena. Euglena, instead of cilia, has a flagellum that is uses for locomotion. Euglena also has an eyespot that is sensitive to light and have green chlorophyll pigment. Amoebas have no fixed shape and have no cilia or flagella. They move by use of pseudopodia.
