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 ...
The plasmodiophores [1] (also known as plasmophorids [2] or plasmodiophorids [3]) are a group of obligate endoparasitic protists belonging to the subphylum Endomyxa in Cercozoa. [4] Taxonomically, they are united under a single family Plasmodiophoridae , order Plasmodiophorida , sister to the phagomyxids .
Actinophrys species belong to an informal group known as heliozoa, which are unicellular eukaryotes (or protists) that are heterotrophic (also known as protozoa) and present stiff radiating arms known as axopodia. [3] [4] In particular, Actinophrys species are characterized by axonemes consisting of double interlocking spirals of microtubules.
Amorphea [1] is a taxonomic supergroup that includes the basal Amoebozoa and Obazoa. That latter contains the Opisthokonta, which includes the Fungi, Animals and the Choanomonada, or Choanoflagellates. The taxonomic affinities of the members of this clade were originally described and proposed by Thomas Cavalier-Smith in 2002. [2] [4]
[4] Many orphan groups of free-living protozoa remain left behind, unable to be added to a supergroup, such as: Picozoa (possibly belongs to Archaeplastida with limited certainty), Malawimonadida (thought to be related to Metamonada), Ancyromonadida, Breviatea, Apusomonadida, etc. [1]
Myzozoa [1] is a grouping of specific phyla within Alveolata, [2] [3] that either feed through myzocytosis, or were ancestrally capable of feeding through myzocytosis. [1] Many protist orders are included within Myzozoa. [1] [4] It is sometimes described as a phylum, containing the major subphyla Dinozoa and Apicomplexa, plus minor subphyla. [5]

Haemoproteus is a genus of parasitic protozoa that belong to the Apicomplexa phyla. The megaloschizont cells measured 50 to 100 micrometers. The megaloschizont cells measured 50 to 100 micrometers. The merozoites inside the megaloschizonts were less than 1 micrometer in diameter.
