They both live in water, and they are both single celled (protists).
A euglena has a flagellum for movement, which amoeba and paramecium do not have.
They are both single celled protists, but Euglena is of Euglenozoa phylum, which has flagella, and Paramecium are cillates with cilia for motility.

Euglena, paramecium, and amoeba
Amoeba, paramecium, and euglena
The euglena is much smaller compared to the paramecium, its less than half the size of one paramecium.
Kingdom Protista
Paramecium and Euglena are both single-celled organisms, but they have different modes of movement. Paramecium uses cilia for propulsion, allowing it to move quickly through water, while Euglena uses a whip-like flagellum. Generally, paramecia can move rapidly and may have an advantage in speed over Euglena, but actual comparisons can vary based on environmental conditions and the specific species involved. Thus, in some instances, a paramecium may be able to outrun a euglena.

Some protists include algae, diatoms, paramecium, rotifers, flagellates, amoeba, and giardia. Other protists include trichomonadida, euglena, trichonympha, ceratium, and dinoflagellates.
there are also paramecium and amoeba and protizonenes
