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.

Opisthokonts, basal

Opisthokonts are a group of eukaryotes that include both animals and fungi as well as basal groups that are not classified in these groups. These basal opisthokonts are reasonably categorized as protists and include choanoflagellates, which are the sister or near-sister group of animals.
