Plexaurella Kunzei
''Plexaurella'' is a genus of gorgonian-type octocorals in the family Plexauridae. Species of the genus are typically characterised by their slit-pores, however, there are some which lack this distinguishing feature (e.g. ''P. grisea'').Bayer, FM 1961. Shallow water Octocorallia of the West Indian Region. Studies of the fauna of Curacao and other Caribbean islands. 55. Sclerite examination is necessary for species identification, which reveals the characteristic 4-rayed 'butterfly' spicules of the cortex and the lack of purple sclerites in the axial sheath.

Albert Von Kölliker
Albert von Kölliker (born Rudolf Albert Kölliker'';'' 6 July 18172 November 1905) was a Swiss anatomist, physiologist, and histologist. Biography Albert Kölliker was born in Zurich, Switzerland. His early education was carried on in Zurich, and he entered the university there in 1836. After two years, however, he moved to the University of Bonn, and later to that of Berlin, becoming a pupil of noted physiologists Johannes Peter Müller and of Friedrich Gustav Jakob Henle. He graduated in philosophy at Zurich in 1841, and in medicine at Heidelberg in 1842. The first academic post which he held was that of prosector of anatomy under Henle, but his tenure of this office was briefin 1844 he returned to Zurich University to occupy a chair as professor extraordinary of physiology and comparative anatomy. His stay here was also brief; in 1847 the University of Würzburg, attracted by his rising fame, offered him the post of professor of physiology and of microscopical and comparativ ...

Plexaurella Nutans
''Plexaurella nutans'', the giant slit-pore sea rod, is a tall species of soft coral in the family Plexauridae. It is a relatively uncommon species and is found in shallow seas in the Caribbean region. Description ''Plexaurella nutans'' can grow to a height of over a metre (yard). It has thick cylindrical branches that occasionally fork and which are often slightly clubbed at the tips. These have a diameter of . The polyps are rather large and protrude from round, oval or slit-shaped grooves in the cup-shaped calyces in the coral skeleton. Each of these calyces is on a slight mound giving the coral a dimpled surface. When the polyps are extended, as they usually are, they give the coral a fuzzy appearance. The colour of this coral is usually pale brown, grey or sometimes lavender. Distribution and habitat ''Plexaurella nutans'' is an uncommon species and occurs at depths down to in the Caribbean Sea, the Bahamas and Florida. It is usually found on isolated patch reefs or on fo ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...
