In the system of classification published in 1964 by B.M. Honigsberg and colleagues, the phylum Protozoa was divided according to the means of locomotion, such as by cilia or flagella. [ 26 ] Despite awareness that the traditional Protozoa was not a clade , a natural group with a common ancestor, some authors have continued to use the name ...
[1] [b] In the 21st century, the classification shifted toward a two-kingdom system of protists: Chromista (containing the chromalveolate, rhizarian and hacrobian groups) and Protozoa (containing excavates and all protists more closely related to animals and fungi). [2] The following groups contain protists.

It gets its name from the combination of "Sarcodina" (which is an older term used for amoeboids) [4] and "Mastigophora" (which is an older term for flagellates). The characteristics of phylum sarcomastigophora are : (1) Nucleus is of one type except in the stages of certain foraminifera. (2) Locomotory organ either pseudopodia or flagella or both.
The hierarchy of biological classification's eight major taxonomic ranks.A domain contains one or more kingdoms. Intermediate minor rankings are not shown. In biology, a kingdom is the second highest taxonomic rank, just below domain.
On the basis that apicomplexans possess a plastid surrounded by four membranes, and that peridinin dinoflagellates possess a plastid surrounded by three membranes, Petersen et al. [25] have been unable to rule out that the shared stramenopile-alveolate plastid could have been recycled multiple times in the alveolate phylum, the source being ...
Ciliate species range in size from as little as 10 μm in some colpodeans to as much as 4 mm in length in some geleiids, and include some of the most morphologically complex protozoans. [4] [5] In most systems of taxonomy, "Ciliophora" is ranked as a phylum [6] under any of several kingdoms, including Chromista, [7] Protista [8] or Protozoa. [9]
The name DRIP is an acronym for the first protozoa identified as members of the group, [5] Cavalier-Smith later treated them as the class Ichthyosporea, since they were all parasites of fish. order Dermocystida "D": Dermocystidium. One species, Rhinosporidium seeberi, infects birds and mammals, including humans.
