## Amoebozoa

Amoebozoa are a group of motile amoeboid protists, members of this group move or feed by means of temporary projections, called pseudopods. The best known member of this group is the slime mold, which has been studied for centuries; other members include the Archamoebae, Tubulinea and Flabellinia. Some Amoeboza cause disease.
