In older classification systems, most amoebae were placed in the class or subphylum Sarcodina, a grouping of single-celled organisms that possess pseudopods or move by protoplasmic flow. Sensitivity of Amoeba Proteus: Amoeba proteus gives negative response to mechanical obstacle. When it is pricked or touched by a rod it turns to avoid the obsta­cle. 3. The requirement is the availability of water. This process regulates the amount of water present in the cytoplasm of the amoeba. This small protozoan uses tentacular protuberances called pseudopodia to move and phagocytose smaller unicellular organisms, which are enveloped inside the cell's cytoplasm in a food vacuole, where they are slowly broken down by enzymes. Just before it reproduces, it rounds up into a ball with tiny pseudopodia extensions. The earliest record of an organism resembling Amoeba was produced in 1755 by August Johann Rösel von Rosenhof, who named his discovery "der kleine Proteus" ("the little Proteus"), after Proteus, the shape-shifting sea-god of Greek Mythology.

Traditionally, amoebas are grouped under the Kingdom Protista as they are neither classified as a plant, animal nor fungus. Amoeba proteus Pallas, 1766, is the most known species of a genus of protists previously inserted in the phylum Rhizopoda, but presently, on the base of molecular data, classified as phylum Amoebozoa, belonging to the Kingdom of the protists.We have however to keep in mind that the classification of the protists is presently much debated. Of six species found in the human alimentary tract, Entamoeba histolytica causes amebic dysentery.
