Franz Martin Hilgendorf
Franz Martin Hilgendorf (5 December 1839 – 5 July 1904) was a German zoologist and paleontologist. Hilgendorf's research on fossil snails from the Steinheim crater in the early 1860s became a palaeontological evidence for the theory of evolution published by Charles Darwin in 1859. Life and work Franz Hilgendorf was born on 5 December 1839 in Neudamm (Mark Brandenburg). Between 1851 and 1854 he went to a gymnasium in Königsberg (Neumark) and later to the Gymnasium ''Zum Grauen Kloster'' (Grey Monastery) in Berlin where he graduated in 1858. In 1859 he started studying philology at the University of Berlin. After four semesters he changed to the University of Tübingen. In the summer of 1862 he joined an excavation by Friedrich August Quenstedt in the Steinheim crater. In 1863 Hilgendorf received his Ph.D. for work related to this excavation. He finished his research on the fossils during his time at the Museum für Naturkunde in Berlin. In 1868, Hilgendorf became ...

Dębno
Dębno (german: Neudamm) is a town in Myślibórz County, West Pomeranian Voivodeship in western Poland. As of December 2021, the town has a population of 13,443. After the Migration Period, the area was populated by West Slavic peoples since the 6th century. Later, it was invaded by Saxons immediately after the invasion and annexation of the Catholic Duchy of Kopanica. The castle of Dębno belonged to the House of Odrowąż. Dębno is known for hosting the oldest marathon in Poland (since 1969), one of the five marathons included in the Crown of Polish Marathons, along with marathons in Kraków, Poznań, Warsaw and Wrocław.

Friedrich August Quenstedt
Friedrich August von Quenstedt (July 10, 1809 – December 21, 1889), was a German geologist and palaeontologist. Life Von Quenstedt was born at Eisleben in Saxony, and educated at the Humboldt University of Berlin. After a period as assistant in the mineralogical museum, he was appointed associate professor (1837) and then professor (1841) of mineralogy and geognosy at the Eberhard Karls Universität Tübingen. Work His earlier work related chiefly to crystallography and mineralogy, on which subjects he published text-books that were widely used. However, he also became distinguished for his researches on palaeontology, and especially for those on the fossils of the Jurassic system. In 1845, he devised a trinomial system of nomenclature for Jurassic ammonites, which has caused some difficulty for later taxonomists.J.H. Callomon, D. T. Donovan, & M. K. Howarth "F. A.

Henry Weed Fowler
Henry Weed Fowler (March 23, 1878 – June 21, 1965) was an American zoologist born in Holmesburg, Pennsylvania. He studied at Stanford University under David Starr Jordan. He joined the Academy of Natural Sciences in Philadelphia and worked as an assistant from 1903 to 1922, associate curator of vertebrates from 1922 to 1934, curator of fish and reptiles from 1934 to 1940 and curator of fish from 1940 to 1965. He published material on numerous topics including crustaceans, birds, reptiles and amphibians, but his most important work was on fish. In 1927 he co-founded the American Society of Ichthyologists and Herpetologists and acted as treasurer until the end of 1927. In 1934 he went to Cuba, alongside Charles Cadwalader (president of the Academy of Natural Sciences of Philadelphia), at the invitation of Ernest Hemingway to study billfishes, he stayed with Hemingway for six weeks and the three men developed a friendship which continued after this trip and Hemingway sent speci ...

David Starr Jordan
David Starr Jordan (January 19, 1851 – September 19, 1931) was the founding president of Stanford University, serving from 1891 to 1913. He was an ichthyologist during his research career. Prior to serving as president of Stanford University, he had served as president of Indiana University from 1884 to 1891. Starr was also a strong supporter of eugenics, and his published views expressed a fear of "race-degeneration" and asserted that cattle and human beings are "governed by the same laws of selection". He was an antimilitarist since he believed that war killed off the best members of the gene pool, and he initially opposed American involvement in World War I. Early life and career Jordan was born in Gainesville, New York, and grew up on a farm in upstate New York. His parents made the unorthodox decision to educate him at a local girls' high school. His middle name, Starr, does not appear in early census records, and was apparently self-selected; he had begun using ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ludwig Heinrich Philipp Döderlein
Ludwig Heinrich Philipp Döderlein (3 March 1855, Bad Bergzabern – 23 April 1936, Munich) was a German zoologist. He specialized in echinoderms, particularly sea stars, sea urchins, and crinoids. He was one of the first European zoologists to have the opportunity to do research work in Japan from 1879 to 1881. Today, he is considered one of the most important pioneers of marine biological research in Japan. He was the director and curator of the Musée zoologique de la ville de Strasbourg from 1882 to 1919. He headed the Zoologische Staatssammlung München from 1923 to 1927 and was Professor of Zoology in the Ludwig Maximilian University of Munich. Biography Ludwig Döderlein was born in Bad Bergzabern, then Kingdom of Bavaria, on March 3, 1855. He went to school in Bayreuth from 1864 to 1873. From 1873 to 1875 he studied natural sciences in the University of Erlangen, where he also worked as an assistant to the Zoologist Emil Selenka in the summer of 1875. From 1875 to 1876 ...

Helicolenus Hilgendorfii
''Helicolenus hilgendorfii'', Hilgendorf's saucord, is a species of marine ray-finned fish belonging to the subfamily Sebastinae, part of the family Scorpaenidae. It is found in the northwestern Pacific Ocean. Taxonomy ''Helicolenus hilgendorfii'' was first formally described in 1884 as ''Sebastes hilgendorfii'' by the German zoologist Ludwig Heinrich Philipp Döderlein with the type locality given as Tokyo, although no types are known. Döderlein did not state who was honoured in the specific name but it is certainly the German zoologist and palaeontologist Franz Martin Hilgendorf whose work on Japanese fishes was often referred to by Döderlein. Description ''Helicolenus hilgendorfii'' attains a maximum standard length of . It has an elongated, compressed body with a large head which has weak spines. The orbit protrudes a little over the dorsal profile of the head. They do not have a swim bladder. There are no teeth in the front of the jaws. The preoperculum has 5 spines an ...

Cypridina Hilgendorfii
''Vargula hilgendorfii'', sometimes called the sea-firefly and one of three bioluminescent species known in Japan as umi-hotaru (海蛍), is a species of ostracod crustacean. It is the only member of genus '' Vargula'' to inhabit Japanese waters; all other members of its genus inhabit the Gulf of Mexico, the Caribbean Sea, and waters off the coast of California. ''V. hilgendorfii'' was formerly more common, but its numbers have fallen significantly. Description ''V. hilgendorfii'' is a small animal, only 3 millimetres long. It is nocturnal and lives in the sand at the bottom of shallow water. At night, it feeds actively. Bioluminescence ''V. hilgendorfii'' is known for its bioluminescence. It produces a blue-coloured light by a specialized chemical reaction of the substrate luciferin and the enzyme luciferase. The luciferase enzyme consists of a 555-amino acid-long peptide with a molecular mass of 61627 u, while the luciferine vargulin has only a mass of 405.5 u. A ...

Crustacean
Crustaceans (Crustacea, ) form a large, diverse arthropod taxon which includes such animals as decapods, seed shrimp, branchiopods, fish lice, krill, remipedes, isopods, barnacles, copepods, amphipods and mantis shrimp. The crustacean group can be treated as a subphylum under the clade Mandibulata. It is now well accepted that the hexapods emerged deep in the Crustacean group, with the completed group referred to as Pancrustacea. Some crustaceans (Remipedia, Cephalocarida, Branchiopoda) are more closely related to insects and the other hexapods than they are to certain other crustaceans. The 67,000 described species range in size from '' Stygotantulus stocki'' at , to the Japanese spider crab with a leg span of up to and a mass of . Like other arthropods, crustaceans have an exoskeleton, which they moult to grow. They are distinguished from other groups of arthropods, such as insects, myriapods and chelicerates, by the possession of biramous (two-parted) limbs, and by th ...

Ostracod
Ostracods, or ostracodes, are a class of the Crustacea (class Ostracoda), sometimes known as seed shrimp. Some 70,000 species (only 13,000 of which are extant) have been identified, grouped into several orders. They are small crustaceans, typically around in size, but varying from in the case of ''Gigantocypris''. Their bodies are flattened from side to side and protected by a bivalve-like, chitinous or calcareous valve or "shell". The hinge of the two valves is in the upper (dorsal) region of the body. Ostracods are grouped together based on gross morphology. While early work indicated the group may not be monophyletic and early molecular phylogeny was ambiguous on this front, recent combined analyses of molecular and morphological data found support for monophyly in analyses with broadest taxon sampling. Ecologically, marine ostracods can be part of the zooplankton or (most commonly) are part of the benthos, living on or inside the upper layer of the sea floor. While Myodoc ...

Gustav Wilhelm Müller
Christian Gustav Wilhelm Müller (17 February 1857, Mühlberg near Erfurt – 18 February 1940) was a German zoologist specializing in Ostracoda. In 1895 he succeeded Carl Eduard Adolph Gerstaecker as director of the zoological museum at Greifswald, a position he maintained until 1923. He was the taxonomic authority of numerous taxa in Ostracoda; a few examples being the subfamily Conchoeciinae and the genera ''Archiconchoecia'', ''Cytherois'' and ''Stenocypria''. In 1965, the genus '' Muellerina'' Bassiouni (family Hemicytheridae) was named in his honor.
