Amoebas belong to the domain eukarya, the kingdom protist, the phyllum protozoa, the class rhizopoda, the order amoebida and the family amoebidae. This is the scientific classification of the genus amoeba, which includes many species of amoeba.
The classification of living things in biology is called the taxonomy, nomenclature or scheme. Amoeba proteus is a representative example of the species, whose members are characterized by an amorphous shape and a method of propulsion facilitated by a feature called the pseudopod. This feature of the amoeba is also instrumental for feeding. All protists, the amoeba included, are single-celled animals containing a nucleus.
Specifically, amoebas are part of the phylum Amoebozoa, as described by Max Lühe in 1913. In 2002-2003, they were placed into the kingdom Protozoa by Thomas Cavalier-Smith. They are also classified under the domain Eukaryota, as described in 1998 by Cavalier-Smith. The species or genus was first described in 1822 by Bory de Saint-Vincent and later added to the family Amoebidae. There are four major subspecies of amoebas identified as of 2014.
