Erik Bertelsen
Erik Bertelsen (8 August 1912 – 18 March 1993) was a Danish ichthyologist, who specialised in deep sea fish. The fish, '' Diaphus bertelseni'' is named in his honour. He studied biology at the University of Copenhagen (1930 -) and in 1937 started work on the Dana collection at Charlottenlund Castle and also for the Danish Fisheries Investigation (DFI). He earned a doctorate in 1951 with his dissertation, ''The ceratioid fishes. Ontology, taxonomy, distribution and biology''. He was director of DFI from 1958 to 1971, when he resigned to work at the zoological museum of the University of Copenhagen, where with fewer administrative duties he was able to concentrate on his research on deep sea fish. In 1961 he was made a Knight of the Order of the Dannebrog. He authored over 50 taxa. See :Taxa named by Erik Bertelsen and wikidata query His zoological author abbreviation is Bertelsen. In 1932 he participated in a fisheries biology research trip to the Faroe Islands and Iceland. I ...

Gerhard Krefft
Gerhard Krefft (30 March 1912 - 20 March 1993) was a German ichthyologist and herpetologist.Stehmann & Hulley (1994). Family His father was a neurologist, who "was an enthusiastic collector of living reptiles and amphibians", and his mother was a concert singer.Stehmann & Hulley (1994), p.558. He and his wife Ingeborg were married in 1947, and they had three daughters.Stehmann & Hulley (1994), p.559. He was the great-nephew of the zoologist, palaeontologist, and Curator of the Australian Museum, Johann Ludwig (Louis) Gerard Krefft (1830–1881). Professional career He had more than 160 scientific publications, many of which were "milestone contributions to the taxonomy and zoogeography Zoogeography is the branch of the science of biogeography that is concerned with geographic distribution (present and past) of animal species. As a multifaceted field of study, zoogeography incorporates methods of molecular biology, genetics, mo ... of oceanic fishes".Stehmann & Hulley (199 ...

Norman Bertram Marshall
Norman Bertram Marshall, known as Freddy, (5 February 1915 – 13 February 1996) was a British marine biologist and ichthyologist who was worked at the British Museum (Natural History). His main interests were in the area of deep sea research. Early life Freddy Marshall was born in the Cambridgeshire village of Great Shelford, where his family had lived for generations in a house built by his father; both his father and grandfather were builders. He was the eldest of four children, having two brothers and a sister. His father joined the Cambridgeshire Regiment and went to fight in the First World War in France before Freddy was born. From 1920 he attended the village's church school and in 1926 went to the Cambridge and County High School. During his school years Freddy was more interested in fishing than in his studies and narrowly avoided expulsion. However, he attained a Higher School Certificate with distinctions in zoology and botany. Cambridge and early career In 1933 Marsh ...

Waryfish
Waryfishes are deep-sea aulopiform fishes in the small family Notosudidae. They are thought to have a circumglobal distribution in subarctic to subantarctic waters. The family name Notosudidae derives from the Greek ''noton'' (back) and Latin ''sudis'' (a fish, ''esox'', the name of salmon). Description Waryfishes are slender, scaled fish, similar in appearance to lancetfishes, but lacking the greatly enlarged dorsal fin. Although the adults are deep-water fish, the larvae inhabit surface waters, and are unique in having teeth on their upper jaws. Waryfishes lack a swim bladder. * Dorsal fin: 9-14 rays * Anal fin: 16-21 rays * Pectoral fin: 10-15 rays * Scales in lateral line The lateral line, also called the lateral line organ (LLO), is a system of sensory organs found in fish, used to detect movement, vibration, and pressure gradients in the surrounding water. The sensory ability is achieved via modified epithelial ...: 44-65 References * {{Taxonbar, from=Q136731 ...

Taxa Named By Erik Bertelsen
In biology, a taxon (back-formation from ''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 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 system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the intr ...
