Selenidium Pendula
''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. pendija''). 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 micro ...

Eukaryota
Eukaryotes () are organisms whose cells have a nucleus. All animals, plants, fungi, and many unicellular organisms, are Eukaryotes. They belong to the group of organisms Eukaryota or Eukarya, which is one of the three domains of life. Bacteria and Archaea (both prokaryotes) make up the other two domains. The eukaryotes are usually now regarded as having emerged in the Archaea or as a sister of the Asgard archaea. This implies that there are only two domains of life, Bacteria and Archaea, with eukaryotes incorporated among archaea. Eukaryotes represent a small minority of the number of organisms, but, due to their generally much larger size, their collective global biomass is estimated to be about equal to that of prokaryotes. Eukaryotes emerged approximately 2.3–1.8 billion years ago, during the Proterozoic eon, likely as Flagellated cell, flagellated phagotrophs. Their name comes from the Greek language, Greek wikt:εὖ, εὖ (''eu'', "well" or "good") and wikt:� ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
