Myzozoa

Within Myzozoa, there are four phyla: • Apicomplexa – parasitic protozoa that lack axonemal locomotive structures except in gametes • Dinoflagellata – mostly marine flagellates many of which have chloroplasts • Chromerida – a marine phylum of photosynthetic protozoa • Perkinsozoa ==Evolution==

The most closely related large clade to the myzozoans are the ciliates. plus the smaller groups discussed above. All Myzozoa appears to have evolved from an ancestor that possessed plastids, required through endosymbiosis. The branching order within both Myzozoa and Protalveolata, is only partly understood. Three groups – the colpodellids, Chromerida and the Apicomplexa – appear to be sister clades. Three other groups – the perkinsids, Syndiniales and Oxyrrhis are distantly related to the dinoflagellates. ==Notes==
