Amoeba

views updated

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.
