Dictyostelium discoideum
The best known amoeboid protists are "Chaos carolinense" and "Amoeba proteus", both of which have been widely cultivated and studied in classrooms and laboratories. Other well known species include the so-called "brain-eating amoeba" "Naegleria fowleri", the intestinal parasite "Entamoeba histolytica", which causes amoebic dysentery, and the multicellular "social amoeba" or slime mould "Dictyostelium discoideum".
