Several species of Amoeba are known ,Amoeba proteus (Gr, amoib= change ) is commonest and best known .Other common species are .Aradiosa ,A discoides and A verrucosa. The following description is largely based on A proteus.

The water is then filtered and allowed to stand open for 2to 3 days .This allows abundant bacterial growth in it ,Now some half rotten leaves are brought from a pond or ditch, washed ant put into the filtrate.
