An amoeba often called amoeboid, is a type of cell or organism which has the ability to alter its shape, primarily by extending and retracting pseudopods. Amoebas do not form an individual taxonomic group instead, they can be found in every major lineage of eukaryotic organisms. Amoeboid cells occur not only among the protozoa, but also in fungi, algae, and animals.Visit here https://www.youtube.com/watch?v=kguStZtssdg&t=25s https://speakerdeck.com/frozen
