Selenidium Cirratuli
''Selenidium'' is a genus of parasitic alveolates in the phylum Apicomplexa. Species in this genus infect marine invertebrates. Taxonomy This genus was created by Giard in 1884.Giard A (1884). Note sur un nouveau groups de protozoaire parasites des annelides et sur q points de l'histoire des gregarines (''S. pendula''). C r Assoc fr Avnnc Set, Cotigr Blois p. 19 Fifty six species have been described in this genus. The type species is '' Selenidium pendula'' Giard, 1884. Description All species in this genus infect marine invertebrates. Life cycle These species infect the gut of polychaete worms. The trophozoites are vermiform with an apical complex. They have few epicytic folds. A dense array of microtubules lies under a trilayered pellicle. Syzygy occurs in the tail-to-tail, head-to-head and lateral positions. The gamonts are extracellular. They are foliaceous or cylindroid in shape and have longitudinal striations. The oocysts are spherical or ovoid, are 12-18 microns i ...

Eukaryota
The eukaryotes ( ) constitute the Domain (biology), domain of Eukaryota or Eukarya, organisms whose Cell (biology), cells have a membrane-bound cell nucleus, nucleus. All animals, plants, Fungus, fungi, seaweeds, and many unicellular organisms are eukaryotes. They constitute a major group of Outline of life forms, life forms alongside the two groups of prokaryotes: the Bacteria and the Archaea. Eukaryotes represent a small minority of the number of organisms, but given their generally much larger size, their collective global biomass is much larger than that of prokaryotes. The eukaryotes emerged within the archaeal Kingdom (biology), kingdom Asgard (Archaea), Promethearchaeati and its sole phylum Promethearchaeota. This implies that there are only Two-domain system, two domains of life, Bacteria and Archaea, with eukaryotes incorporated among the Archaea. Eukaryotes first emerged during the Paleoproterozoic, likely as Flagellated cell, flagellated cells. The leading evolutiona ...
