Further, as taxonomy pays no account of molecular phylogeny, one current classification has all alveolate taxa other than apicomplexans, ciliates and dinoflagellates, named under the grab bag term "Protalveolata".

[7] The difficulty of placing very early dinozoans either within or outside the group "dinoflagellates" continues to favour classifications such as Protalveolata,[7] as does the potential polyphyly between the two genera of "colpodellids" Voromonas and Colpodella.

[1] Both of these groups of organisms – unlike the majority of eukaryotes studied to date – seem to have a linear mitochondrial genome.

All Myzozoa appears to have evolved from an ancestor that possessed plastids, required through endosymbiosis.

[13] Chromerida are ancestrally myzocytotic, on the basis of evidence for myzocytosis by the chromerid Vitrella brassicaformis.
