Myzozoa

Myzozoa is a grouping of Alveolata,[1][2] that feed through myzocytosis.

Several protozoan species group in Myzozoa.[3]

It is sometimes described as a phylum, containing the subphyla Dinozoa and Apicomplexa.[4]

The term "Miozoa" is also used.[5]

Evolution

The closest relation to this clade are the ciliates.

Both these groups of organisms — unlike the majority of eukaryotes studied to date — seem to have linear mitochnodrial genome. Most other eukaryotes that have had their mitochondrial genomes examined have circular genomes.

The branching order of this clade is only partly understood. The Colpodellids and the Apicomplexa appear to be sister clades as do the perkinsids and the dinoflagelates.[6] The positions of the other members of this phylum remains unclear at present.

The Chromerida and the Colpodellida appear to be sister clades with the Dinozoa being more closely related to the perkinsids and the dinoflagelates.[7]

Notes

Perkinsus marinus and the Apicomplexa both have histones while the dinoflagellates appear to have lost theirs.[8]
