Aristostomias Scintillans
''Aristostomias'' is a genus of barbeled dragonfishes native to the ocean depths in the Pacific, Atlantic and Indian Ocean, Indian oceans. Red Light Bioluminescence Production of red light bioluminescence Similar to other deep-sea organisms that are capable of producing red light bioluminescence, including ''Pachystomias'', ''Aristostomias'' has large suborbital photophores that produce red-shifted cold light. In addition, ''Aristostomias'' has postorbital photophores that emit blue-green light. Visual systems Most meso- and bathypelagic fish are only able to see shortwave light, as their retinae possess rods with rhodopsins sensitive to blue light. ''Aristostomias'' is able to detect red-shifted light, as their retinae have long-wave absorbing rhodopsins and porphyropsins that can detect wavelengths of up to 590 nm. ''Aristostomias'' can detect red light at distances of up to 2 meters, suggesting that detection is used primarily for close-range intraspecific communic ...

Erich Zugmayer
Erich Johann Georg Zugmayer (16 May 1879, Vienna – 13 February 1938) was an Austrian zoologist and ichthyologist who worked in the Austrian foreign ministry. He collected extensively in Asia where he went on several expeditions including Western Tibet (1906) and Baluchistan (1911). He described several new species of fishes and several bird taxa were described from his collections. Life and work Zugmayer was born in Vienna to Heinrich Zugmayer (1841-1917, director of the metal-making firm of Zugmayer) and his wife Emilie, née Hoffmann (d. 1926). A cousin was the zoologist Hans Hass (1919-2013). He studied liberal arts before studying commerce in London and working in trade and then gave up to study natural sciences at Heidelberg University from 1900. He was influenced by Otto Bütschli, Theodor Curtius, Curt Herbst, Alfred Hettner, Albrecht Kossel, Friedrich Krafft, Robert Lauterborn, Hermann Karl Rosenbusch , Wilhelm Salomon-Calvi and August Schuberg.

Stomiidae
Stomiidae is a family of deep-sea ray-finned fish, including the barbeled dragonfishes, that live in all oceans in a wide range of depths. They are quite small, usually around 15 cm, up to 26 cm, and they exhibit a strong sexual dimorphism. These fish are apex predators and have enormous jaws filled with fang-like teeth. They are also able to hinge the neurocranium and upper-jaw system, which leads to the opening of the jaw to more than 100 degrees. This ability allows them to consume extremely large prey, often 50% greater than their standard length. Evolution Due to their extreme habitats, stomiids are very rare in the fossil record. The oldest known genus is '' Azemiolestes'' Prokofiev, 2001 from the Middle Eocene (Lutetian) of Georgia. Other fossil genera include '' Abruzzoichthys'' Carnevale, 2002 from the Middle Miocene of Italy and '' Mrazecia'' Pauca, 1929 from the Early Oligocene of Romania.

William Welsh Welsh
William is a masculine given name of Germanic origin. It became popular in England after the Norman conquest in 1066,All Things William"Meaning & Origin of the Name"/ref> and remained so throughout the Middle Ages and into the modern era. It is sometimes abbreviated "Wm." Shortened familiar versions in English include Will or Wil, Wills, Willy, Willie, Bill, Billie, and Billy. A common Irish form is Liam. Scottish diminutives include Wull, Willie or Wullie (as in Oor Wullie). Female forms include Willa, Willemina, Wilma and Wilhelmina. Etymology William is related to the German given name ''Wilhelm''. Both ultimately descend from Proto-Germanic ''*Wiljahelmaz'', with a direct cognate also in the Old Norse name ''Vilhjalmr'' and a West Germanic borrowing into Medieval Latin ''Willelmus''. The Proto-Germanic name is a compound of *''wiljô'' "will, wish, desire" and *''helmaz'' "helm, helmet".Hanks, Hardcastle and Hodges, ''Oxford Dictionary of First Names'', Oxford Unive ...

Charles Henry Gilbert
Charles Henry Gilbert (December 5, 1859 in Rockford, Illinois – April 20, 1928 in Palo Alto, California) was a pioneer ichthyologist and Fisheries science, fishery biologist of particular significance to natural history of the western United States. He collected and studied fishes from Central America north to Alaska and described many new species. Later he became an expert on Pacific salmon and was a noted conservation movement, conservationist of the Pacific Northwest. He is considered by many as the intellectual founder of American fisheries biology. He was one of the 22 "pioneer professors" (founding faculty) of Stanford University. Early life and education Born in Rockford, Illinois, Gilbert spent his early years in Indianapolis, Indiana, where he came under the influence of his high school teacher, David Starr Jordan (1851‒1931). When Jordan became Professor of Natural History at Butler University in Indianapolis, Gilbert followed and received his B.A. degree in 187 ...

Ethelwynn Trewavas
Ethelwynn Trewavas (5 November 1900 – 16 August 1993) was an ichthyologist at the British Museum of Natural History. She was known for her work on the families Cichlidae and Sciaenidae. She worked with Charles Tate Regan, another ichthyologist and taxonomist. Academic studies and career She received her bachelor's degree and Board of Education Certificate in Teaching in 1921 from Reading University, and then worked as a teacher before being employed by the King's College of Household and Social Science as a part-time demonstrator, spending most of her time on research. She was taught by Dr. Nellie B. Eales when associated with the Freshwater Biological Association. She met Charles Regan and was employed by him as his assistant until hired by the British Museum (Natural History) as Assistant Keeper in 1935. She was appointed Deputy Keeper of Zoology in 1958, and retired in 1961. She served as the senior scientist in the Fish Section of the British Museum (Natural Hi ...

Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. 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 of an ancestral taxon are grouped together (i.e. Phylogeneti ...

Charles Tate Regan
Charles Tate Regan (1 February 1878 – 12 January 1943) was a British ichthyology, ichthyologist, working mainly around the beginning of the 20th century. He did extensive work on fish classification schemes. Born in Sherborne, Dorset, he was educated at Derby School and Queens' College, Cambridge and in 1901 joined the staff of the Natural History Museum, London, Natural History Museum, where he became Keeper of Zoology, and later director of the entire museum, in which role he served from 1927 to 1938. Regan was elected Fellow of the Royal Society in 1917. Regan mentored a number of scientists, among them Ethelwynn Trewavas, who continued his work at the British Natural History Museum. Taxon described by him *See :Taxa named by Charles Tate Regan Among the species he described is the Siamese fighting fish (''Betta splendens''). In turn, a number of fish species have been named ''regani'' in his honour: Taxon named in his honor *A Thorny Catfish ''Anadoras regani'' (Stein ...
