Rhabdospora Thelohani
''Rhabdospora'' is a genus assigned to cells found in a variety of fish. First reported in 1892, there has since been disagreement over whether ''Rhabdospora'' represents a parasite of the phylum '' Apicomplexa'' or a specialized fish cell. History In 1892, Thélohan described unusual looking cells from the intestine of various fishes. In 1895, Laguessé named these cells ''Rhabdospora thelohani'' or "rodlet cells", determining them to be parasites that infect the fish. Since then, there has been disagreement over whether ''R. thelohani'' is an Apicomplexan parasite or a specialized intestinal fish cell. Description The exact nature and status of this genus remains an open question. Some authors consider the descriptions of this species to be an error while others have reported features consistent with its inclusion in the Apicomplexia.

Eukaryota
Eukaryotes () are organisms whose Cell (biology), cells have a cell nucleus, 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-domain system, 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), Asgard archaea. This implies that there are only Two-domain system, 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 (ecology), 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. The ...
