Amoebas are a genus of single-celled eukaryotic organisms (classified as protozoans).
They are considered animal-like because they feed heterotrophically.
The structure of amoebas is usually examined using the typical example of the common amoeba (Amoeba proteus).
Amoebas are widespread in freshwater, and less commonly in marine waters.
They feed on bacteria and single-celled organisms.
