Amoeboid Group (Sarcodina) (Rhizopoda-Actinopoda, or Sarcodina) contains the familiar Amoeba studied in elementary biology. There are probably over 200 species of amoeba-like animals which vary greatly in size. The largest ones, although still very small,  can be viewed with the naked eye. A one thousand power microscope is required to view some of the very tiny species. These animals extend a foot or pseudopod for locomotion.
