Podiata Families
Podiates (Thomas Cavalier-Smith, Cavalier-Smith, 2012, excl. Ancyromonadida) are a proposed clade containing the Amorphea (incl. Opisthokonta, Amoebozoa, apusomonads and breviates) and the organisms now assigned to the clade CRuMs. Ancyromonadida does not appear to have emerged in this grouping. Sarcomastigota (Cavalier-Smith, 1983) is a proposed subkingdom (currently shown to be paraphyletic) that includes all the podiates that are ''not'' animals or fungi. Sulcozoa (Thomas Cavalier-Smith, Cavalier-Smith, 2012) is a proposed phylum (currently shown to be paraphyletic) within Sarcomastigota that does not include the phyla Amoebozoa (clade) and Choanozoa (paraphyletic), i.e. it includes the proposed subphyla Apusozoa and Varisulca.

Agelas Clathrodes
''Agelas clathrodes'', also known as the orange elephant ear sponge, is a species of sea sponge. It lives on reefs in the Caribbean, usually more than below the surface of the ocean. It takes various forms, and its color is reddish orange. Description The orange elephant ear sponge is very variable in form. It may be encrusting, developing a thickness up to thick or have large, flabby lobes or be fan-, tube- or ridge-shaped. Large specimens may combine several of these forms. The surfaces are perforated by small holes, both circular and irregularly elongate, especially on the side away from the current. The flesh is tough, firm and resilient and the thick surface skin is rough to the touch. The colour can vary from yellow, through orange to brick red or brown. This sponge can be confused with ''Agelas citrina'' but that species is usually pinkish or creamy yellow. Another similar species is ''Agelas sventres'' but that has round holes on the exposed side, each with a noticea ...

Paraphyletic
In taxonomy (general), taxonomy, a group is paraphyletic if it consists of the group's most recent common ancestor, last common ancestor and most of its descendants, excluding a few Monophyly, monophyletic subgroups. The group is said to be paraphyletic ''with respect to'' the excluded subgroups. In contrast, a monophyletic group (a clade) includes a common ancestor and ''all'' of its descendants. The terms are commonly used in phylogenetics (a subfield of biology) and in the tree model of historical linguistics. Paraphyletic groups are identified by a combination of Synapomorphy and apomorphy, synapomorphies and symplesiomorphy, symplesiomorphies. If many subgroups are missing from the named group, it is said to be polyparaphyletic. The term was coined by Willi Hennig to apply to well-known taxa like Reptilia (reptiles) which, as commonly named and traditionally defined, is paraphyletic with respect to mammals and birds. Reptilia contains the last common ancestor of reptiles a ...

Apusomonadida
The Apusomonadida are a group of protozoan zooflagellates that glide on surfaces, and mostly consume prokaryotes. They are of particular evolutionary interest because they appear to be the sister group to the Opisthokonts, the clade that includes both animals and fungi. Together with the Breviatea, these form the Obazoa clade.

Breviata
''Breviata anathema'' is a single-celled flagellate amoeboid eukaryote, previously studied under the name ''Mastigamoeba invertens''. The cell lacks mitochondria but has remnant mitochondrial genes, and possesses an organelle believed to be a modified anaerobic mitochondrion, similar to the mitosomes and hydrogenosomes found in other eukaryotes that live in low-oxygen environments. Early molecular data placed ''Breviata'' in the Amoebozoa, but without obvious affinity to known amoebozoan groups. More recently, phylogenomic analysis has shown that the class Breviatea is a sister group to the Opisthokonta and Apusomonadida The Apusomonadida are a group of protozoan zooflagellates that glide on surfaces, and mostly consume prokaryotes.

Obazoa
Obazoa (Brown et al., 2013) is a proposed sister clade of Amoebozoa (which together form Amorphea). Obazoa is composed of Breviatea, Apusomonadida and Opisthokonta. The term Obazoa is based on the OBA acronym for Opisthokonta, Breviatea, and Apusomonadida. Determining the placement of Breviatea and Apusomonadida and their properties is of interest for the development of the opisthokonts in which the main lineages of animals and fungi emerged. The relationships among opisthokonts, breviates and apusomonads are not conclusively resolved (as of 2018), though Breviatea is usually inferred to be the most basal of the three lineages. Ribosomal RNA phylogenies do not usually recover Obazoa as a clade (see for example:), probably reflecting their stemming from a very ancient common ancestor, and little phylogenetic signal Phylogenetic signal is an evolutionary and ecological term, that describes the tendency or the pattern of related biological species to resemble each other more than ...

Unikont
Amorphea are members of a taxonomic supergroup that includes the basal Amoebozoa and Obazoa. That latter contains the Opisthokonta, which includes the Fungi, Animals and the Choanomonada, or Choanoflagellates. The taxonomic affinities of the members of this clade were originally described and proposed by Thomas Cavalier-Smith in 2002. The International Society of Protistologists, the recognised body for taxonomy of protozoa, recommended in 2012 that the term Unikont be changed to Amorphea because the name "Unikont" is based on a hypothesized synapomorphy that the ISP authors and other scientists later rejected. It includes amoebozoa, opisthokonts, and possibly Apusozoa. Taxonomic revisions within this group Cavalier-Smith has proposed two new phyla: Sulcozoa, which consists of the subphyla Apusozoa ( Apusomonadida and Breviatea), and Varisulca, which includes the subphyla Diphyllatea, Discocelida, Mantamonadidae, Planomonadida and Rigifilida. The validity of this p ...

Malawimonas
''Malawimonas'' is a Loukozoa genus, possible sister of the Podiata. History of the discovery of Malawimonads In 1993, Charles J O’ Kelly studied the jakobid groups flagellates and implications for the early diversification of eukaryotes and recognized that ''Jakoba, Reclimonas,'' and ''Histonia'' or often refer as “core jakobids” were morphologically somewhat similar. Interestingly, they included an unnamed and undescribed free-swimming, flagellate, and also groove- bearing cell. During the early study, these cells were thought to be a member from ''Jakoba'' due to the external morphology features that resembles ''Jakoba libera'' in terms of lack of cell covering, sessile trophic stages, swimming in a similar manner and sharing the tendency for the anterior flagellum to form a “crook. However, later discovery found that this species seems to not fit and can not be assigned to the genus ''Jakoba'', nor to any other genus of Jakobids, because of their discoidal mitochond ...

Neozoa
The Scotokaryotes (Cavalier-Smith) is a proposed basal Neokaryote clade as sister of the Diaphoretickes. Basal Scotokaryote groupings are the Metamonads, the Malawimonas and the Podiata. In this phylogeny the Discoba are sometimes seen as paraphyletic and basal Eukaryotes. An alternative to the Unikont–Bikont division was suggested by Derelle ''et al.'' in 2015, where they proposed the acronyms Opimoda–Diphoda respectively, as substitutes to the older terms. The name Opimoda is formed from the letters (shown in capitals) of OPIsthokonta and aMOebozoa. In this phylogeny Discoba belongs to the Diphoda clade. Taxonomy A proposed cladogram is See also *Diphoda A bikont ("two flagella") is any of the eukaryotic organisms classified in the group Bikonta. Many single-celled members of the group, and the presumed ancestor, have two flagella. Enzymes Another shared trait of bikonts is the fusion of two ge ...

Apusozoa
The Apusozoa are an Obazoa phylum comprising several genera of flagellate eukaryotes. They are usually around 5–20 μm in size, and occur in soils and aquatic habitats, where they feed on bacteria. They are grouped together based on the presence of an organic shell or theca under the dorsal surface of the cell. The name derives from the Ancient Greek words for footless () and animal (). This phylum is currently defined as containing the Breviata and the Apusomonadida. However, it currently usually is viewed as paraphyletic, with the Breviata as more basal. The opisthokonts appear to have emerged as sister of the apusomonadida. It has been suggested that the Mantamonadida be classified in Apusozoa. The ancyromonadida appear to be Varisulca, Planomonadida, shifting them possibly more basal than the Amoebozoa, or less basal. While some classification systems have placed Hemimastigida in Apusozoa, 2018 research indicated that hemimastigotes (/Hemimastix/Spironemidae) are thei ...
