Alveolate

The Alveolata is a grouping of protists. One view is that it is a superphylum with at least four phyla.

 Phyla 

 Ciliates, very common protozoa, with many short cilia arranged in rows
 Chromerida – a marine phylum of photosynthetic protozoa
 Apicomplexa, parasitic protozoa that lack locomotive structures except in gametes
 Dinoflagellate, mostly marine flagellates, many of which have chloroplasts
