Solomon Markovitch Herzenstein
Solomon Markovich Herzenstein (; 1854 – August 7, 1894) was a Russian zoologist. Biography Herzenstein received a degree in natural sciences and mathematics from St. Petersburg University and was appointed as the custodian of the Zoological Museum of the Imperial Academy of Science in 1879 or 1880. He also supervised practical training at the University for Women. In 1880, 1884, and 1887, he was commissioned to travel to the Murman Coast of the Kola Peninsula to study the mollusks and fishes there. His work, "Materialy k Faunye Murmanskavo Berega i Byelavo Morya," which was published in the ''Trudy'' of the in 1885, became a standard reference. He co-wrote ''Zamyetki po Ikhtologii Basseina Ryeki Amura'' (1887) and ''Nauchnye Rezultaty Puteshestvi Przevalskavo'' (1888–91) with N. L. Varpakhovski. He also wrote ''Ryby'' (St. Petersburg, 1888-91), and published "Ichthyologische Bemerkungen" in the ' (1890-92). Species described * '' Acanthogobio guentheri'' (Herzenstein, ...

Ray-finned Fish
Actinopterygii (; ), members of which are known as ray-finned fishes, is a class of bony fish. They comprise over 50% of living vertebrate species. The ray-finned fishes are so called because their fins are webs of skin supported by bony or horny spines (rays), as opposed to the fleshy, lobed fins that characterize the class Sarcopterygii (lobe-finned fish). These actinopterygian fin rays attach directly to the proximal or basal skeletal elements, the radials, which represent the link or connection between these fins and the internal skeleton (e.g., pelvic and pectoral girdles). By species count, actinopterygians dominate the vertebrates, and they constitute nearly 99% of the over 30,000 species of fish. They are ubiquitous throughout freshwater and marine environments from the deep sea to the highest mountain streams. Extant species can range in size from ''Paedocypris'', at , to the massive ocean sunfish, at , and the long-bodied oarfish, at . The vast majority of Actinoptery ...

Triplophysa
''Triplophysa'' is a genus of fish in the family Nemacheilidae found mainly in and around the Qinghai-Tibet Plateau in China. Currently, the genus is a mixed assemblage of species. Some lineages have been identified and treated as subgenera (''Hedinichthys'', ''Indotriplophysa'', ''Labiatophysa'', ''Qinghaichthys'' and ''Tarimichthys''), but as Wikipedia follows Fishbase for fish species all but ''Hedinichthys'' have been treated as subgenera in Wikipedia, although Kottelat in his revision of the loaches did recognise them as valid. FishBase, however, includes these in ''Triplophysa'' without specifying subgenera and treats the names given by Kottelat as synonyms. Ecology ''Triplophysa zhaoi'' holds the record for the lowest altitude for Asian fish: it is found at below sea level in swamps of the Lükqün oasis, in the Turpan Depression in Xinjiang. In the other end, ''Triplophysa stolickai'' holds the record altitude for Asian fish: it is found at above sea level in hot sprin ...

Taxa Named By Solomon Herzenstein
In biology, a taxon (back-formation from ''Taxonomy (biology), taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular Taxonomic rank, ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's Linnaean taxonomy, system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard de Jussieu, Bernard and Antoine Laurent de Jussieu.
