Belongs within: Spirotricha.Contains: Strombidinopsidae, Tintinnina, Strobilidiidae. The Choreotrichida are a group of ciliates united by a closed adoral zone of membranelles (secondarily opened slightly in Parastrombidinopsis) and hypoapokinetal stomatogenesis in a pouch. Representatives include Leegaardiella in which the collar polykinetids are bipartited whereas in other taxa they are continuous (Agatha & Strüder-Kypke 2007). <==Choreotrichida [Choreotrichia, Strobilidiina] | i. s.:… Continue reading Choreotrichida

Tetrahymenida
Belongs within: Oligohymenophorea. The model tetrahymenidans Published 15 November 2019 Ciliates have long been one of the most (if not the most) confidently recognised groups of unicellular eukaryotes owing to their distinctive array of features, in particular locomotion by means of more or less dense tracts of small cilia that often run the length of… Continue reading Tetrahymenida
Eimeriorina
Belongs within: Sporozoa.Contains: Eimeria. The Eimeriorina are a group of intracellular parasites in which macro- and microgametes are produced independently (Adl et al. 2019). Characters (from Adl et al. 2019): Microgametes and macrogametes develop independently; syzygy is absent; microgamonts produce large number of cilated microgametes; zygote is nonmotile; sporozoites always enclosed in sporocyst within oocyst.… Continue reading Eimeriorina
Thoracosphaeraceae
Belongs within: Peridiniales.Contains: Scrippsiella. The Thoracosphaeraceae are a group of dinoflagellates of which many members are unique among alveolates in producing calcareous structures, either as resting cysts or during vegetative stages (Gottschling et al. 2005, as Calciodinellaceae). Molecular phylogenies also indicate the inclusion of a number of non-calcareous taxa in this clade. Zooxanthella nutricola is… Continue reading Thoracosphaeraceae
Eugregarinorida
Belongs within: Sporozoa. The Eugregarinorida are a major subgroup of the gregarine parasites, found in a wide range of invertebrate hosts. Let’s you and me enter syzygy Published 9 May 2015 Finally, you and your beloved are together. For the two of you, there are no others; all the world is yours alone. You gaze… Continue reading Eugregarinorida
Aconoidasida
Belongs within: Sporozoa. The Aconoidasida are a group of sporozoans lacking the conoid in at least the asexual stages of the life cycle; members of this group include species of significance to human such as malaria-causing Plasmodium and Theileria causing diseases in livestock. Within the clade, members of the Haemosporida possess ciliated microgametes and a… Continue reading Aconoidasida
Dissodinium
Belongs within: Gymnodinoidia. The life and times of Dissodinium Published 20 June 2018 I’ve referred before to the position of the minute crustaceans known as copepods as one of the major groups of animals making up the marine zooplankton. Copepods form a significant part of the diet for a wide range of other marine animals:… Continue reading Dissodinium
Ceratium
Belongs within: Peridiniphycidae.Contains: Ceratium horridum, Ceratium tripos. Ceratium is a diverse genus of flagellates, including both freshwater and marine species, with three or four horns radiating from the theca. Ceratium… er… Neoceratium… er… Tripos humilis Published 30 July 2013 Ceratium has long been a popular choice as a representative dinoflagellate genus for textbooks, because as… Continue reading Ceratium
Peridiniphycidae
Belongs within: Peridinoidia.Contains: Blepharocysta, Peridiniales, Leptodinioideae, Goniodomaceae, Ceratocorys, Cribroperidinioideae, Ceratium, Gonyaulax. The Peridiniphycidae are a major group of dinoflagellates with a tabulation that accords with, or derives from, a pattern in which there are five or six latitudinal plate series, and which lack a sagittal suture (Adl et al. 2012).

Peridiniaceae
Belongs within: Peridiniales.Contains: Peridinium. The Peridiniaceae are a group of dinoflagellates with a distinct cingulum, containing four to six cingular plates, and at least one intercingular boundary on the dorsal surface (Fensome et al. 1993). Characters (from Fensome et al. 1993): Test with four Kofoid apical plates; five postcingular plates; cingulum distinct with four to… Continue reading Peridiniaceae
