Excavata. Many of the protist species classified into the supergroup Excavata are asymmetrical, single-celled organisms with a feeding groove “excavated” from one side. This supergroup includes heterotrophic predators, photosynthetic species, and parasites. Its subgroups are the diplomonads, parabasalids, and euglenozoans.

Excavata Like Rhizaria, Excavata ( Figures 5(e)–5(j) ) are primarily a collection of protozoa, but also include a single group of secondary algae. The most recent common ancestor of excavates was a flagellate (probably a free-living bacterivore) with a characteristic broad feeding groove, and various extant free-living groups still have this ...
