Myzozoa is a grouping of specific phyla within Alveolata, that either feed through myzocytosis, or were ancestrally capable of feeding through myzocytosis. Many protozoan orders are included within Myzozoa. It is sometimes described as a phylum, containing the major subphyla and Apicomplexa, plus minor subphyla. The term Myzozoa superseded the previous term "Miozoa", by the same authority, and gave a slightly altered meaning.
