Amoebae as specialized cells and life cycle stages[ edit ] Neutrophil white blood cell engulfing anthrax bacteria Some multicellular organisms have amoeboid cells only in certain phases of life, or use amoeboid movements for specialized functions. In the immune system of humans and other animals, amoeboid white blood cells pursue invading organisms, such as bacteria and pathogenic protists, and engulf them by phagocytosis. Both the plasmodial slime moulds, currently classified in the class Myxogastria , and the cellular slime moulds of the groups Acrasida and Dictyosteliida , live as amoebae during their feeding stage. The amoeboid cells of the former combine to form a giant multinucleate organism, [33] while the cells of the latter live separately until food runs out, at which time the amoebae aggregate to form a multicellular migrating "slug" which functions as a single organism.

Both the plasmodial slime moulds, currently classified in the class Myxogastria , and the cellular slime moulds of the groups Acrasida and Dictyosteliida , live as amoebae during their feeding stage. The amoeboid cells of the former combine to form a giant multinucleate organism, [33] while the cells of the latter live separately until food runs out, at which time the amoebae aggregate to form a multicellular migrating "slug" which functions as a single organism. Ehrenberg , adopted the genus in his own classification of microscopic creatures, but changed the spelling to Amoeba.

Within the traditional Sarcodina, amoebae were generally divided into morphological categories , on the basis of the form and structure of their pseudopods. Amoebae with pseudopods supported by regular arrays of microtubules such as the freshwater Heliozoa and marine Radiolaria were classified as Actinopods ; whereas those with unsupported pseudopods were classified as Rhizopods.

Dismantling of Sarcodina[ edit ] In the final decade of the 20th century, a series of molecular phylogenetic analyses confirmed that Sarcodina was not a monophyletic group. In view of these findings, the old scheme was abandoned and the amoebae of Sarcodina were dispersed among many other high-level taxonomic groups. Today, the majority of traditional sarcodines are placed in two eukaryote supergroups : Amoebozoa and Rhizaria.

The rest have been distributed among the excavates , opisthokonts , and stramenopiles. Some, like the Centrohelida , have yet to be placed in any supergroup.
