Amoeba
Amoeba A genus of protoctists (see also
protozoa) of the phylum
Rhizopoda, members of which have temporary body projections called
pseudopodia. These are used for locomotion and feeding and result in a constantly changing body shape (see
amoeboid movement). Most species are free-living in soil, mud, or water, where they feed on smaller protoctists and other single-celled organisms, but a few are parasitic. The best known species is the much studied
A. proteus.
