By 1954, Protozoa were classified as "unicellular animals", as distinct from the "Protophyta", single-celled photosynthetic algae, which were considered primitive plants. [25] 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 ...
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.
This article largely follows the efforts of the scientific community and the International Society of Protistologists to revise the taxonomy of protists in a manner that reflects their phylogeny and evolution, striving away from the use of historical paraphyletic taxa and relying exclusively on clades as the basis of the classification.
Protistology is a scientific discipline devoted to the study of protists, a highly diverse group of eukaryotic organisms. All eukaryotes apart from animals, plants and fungi are considered protists. [1]
[36] [37] Protozoa, like plants and animals, can be considered heterotrophs or autotrophs. [33] Autotrophs like Euglena are capable of producing their energy using photosynthesis, while heterotrophic protozoa consume food by either funneling it through a mouth-like gullet or engulfing it with pseudopods, a form of phagocytosis .

May 2024) (Learn how and when to remove this message) Amoeba, Entamoeba histolytica uses holozoic nutrition. Holozoic nutrition (Greek: holo -whole ; zoikos -of animals) is a type of heterotrophic nutrition that is characterized by the internalization ( ingestion ) and internal processing of liquids or solid food particles.

Tetrahymena thermophila is a species of Ciliophora in the family Tetrahymenidae. [1] It is a free living protozoon and occurs in fresh water. [2]There is little information on the ecology and natural history of this species, [3] but it is the most widely known and widely studied species in the genus Tetrahymena.
Bodo saltans (alternatively known as Pleuromonas jaculans) is a free-living nonparasitic species of kinetoplastid flagellated phagotrophic protozoa that feed on bacteria. [1] Bodo saltans cells have been reported in freshwater and marine environments.
