Max Poll
Max Fernand Leon Poll (21 July 1908 in Ruisbroek – 13 March 1991 in Uccle) was a Belgian ichthyologist who specialised in the Cichlidae. In the years 1946 and 1947 he organised an expedition to Lake Tanganyika. He has described several species of Pseudocrenilabrinae, such as '' Lamprologus signatus'', '' Steatocranus casuarius'', '' Neolamprologus brichardi'', and '' Neolamprologus pulcher''. He was a member of The Royal Academies for Science and the Arts of Belgium, professor at the Université libre de Bruxelles, and conservator at the Royal Museum of the Belgian Congo in Tervuren. He was an honorary member of the American Society of Ichthyologists and Herpetologists. Taxon named in his honor Named after him are species and taxa In biology, a taxon (back-formation from ''taxonomy''; : 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 particula ...

Günther Maul
Günther Edmund Maul (May 7, 1909 – September 28, 1997) was a German ichthyologist and taxidermist in Portugal. Maul came to Madeira in December 1930 to work as taxidermist at Museu Municipal do Funchal, which opened to the public in 1933. He was appointed director for the museum in 1940, a post that he held to his retirement in 1979. He, however, continued his research until shortly before his death. He started two journals (''Boletim do Museu Municipal do Funchal'' in 1945 and ''Bocagiana'' in 1959) and opened the museum's aquarium to the public in 1959. He also participated in several expeditions including with the French bathyscaphe '' Archimède'' in 1966 and organised the first multidisciplinary expedition to the Salvage Islands in 1963. He was awarded an honorary doctorate from the University of Madeira in 1995. Works He described several species of fish *'' Himantolophus albinares'' *'' Coryphaenoides thelestomus'' *'' Macruronus maderensis'' *'' Rouleina maderensis'' ...

Phosichthyidae
Lightfishes are small stomiiform fishes in the family Phosichthyidae The earliest fossils of lightfishes are of the genus †'' Sytchevskia'' Prokofiev, 2002, known from Middle Eocene-aged Tethyan marine strata in Georgia. They are very small fishes found in oceans throughout the world: most species grow no longer than 10 cm, while those in the genus '' Vinciguerria'' only reach 4 cm or so. They make up for their small size with abundant numbers: '' Vinciguerria'' is thought — with the possible exception of '' Cyclothone'' — to be the most abundant genus of vertebrates. Deep-sea trawls of the Humboldt Current in the southeast Pacific have found that lightfishes make up 85% by mass of mesopelagic fishes, with '' Vinciguerria lucetia'' by far the most numerous species. They are bioluminescent fishes, possessing rows of photophores along their sides, with which they hunt planktonic invertebrates, especially krill, copepod Copepods (; meaning 'oar-feet') are ...

Marion Griswold Grey
Marion Griswold Grey (1911–1964) was an American ichthyologist. The daughter of James and Lucy Griswold, she was born Marion Griswold in Los Angeles and moved to Kenosha, Wisconsin with her family when she was nine. She studied zoology at Wellesley College but left after two years of study. In 1933, she married Arthur L. Grey and moved to Chicago; the couple had three children, including linguist Sarah Thomason. After she brought a pipefish to the Field Museum of Natural History for identification, she was encouraged by Alfred Weed to volunteer at the museum. She gained additional knowledge from informal training while at the museum. From 1943 to 1946, she was put in charge of the Fish Division at the museum on an unpaid basis while curator Loren P. Woods served in the Navy during World War II. She continued to be an associate in the Division of Fishes at the museum until her death in 1964. In 1948, she was a member of the museum's expedition to Bermuda. She learned Russian so ...

Species
A species () is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. It is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour, or ecological niche. In addition, palaeontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. About 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomen". The first part of a binomen is the name of a genus to which the species belongs. The second part is called the specific name (zoology), specific name or the specific ...

Monotypic Taxon
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of Genus, genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. Theoretical implications Monotypic taxa present several important theoretical challenges in biological classification. One key issue is known as "Gregg's Paradox": if a single species is the only member of multiple hierarchical levels (for example, being the only species in its genus, which is the only genus in its family), then each level needs a distinct definition to maintain logical structure. Otherwise, the different taxonomic ranks become effectively identical, which creates problems for organizing biological diversity in a hierarchical o ...

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 ...

Stomiiformes
Stomiiformes is an order (biology), order of deep-sea ray-finned fishes of very diverse Morphology (biology), morphology. It includes, for example, Barbeled dragonfish, dragonfishes, lightfishes (Gonostomatidae and Phosichthyidae), loosejaws, marine hatchetfishes and viperfishes. The order contains 4 family (biology), families (5 according to some authors) with more than 50 genus, genera and at least 410 species. As usual for deep-sea fishes, there are few common names for species of the order, but the Stomiiformes as a whole are often called dragonfishes and allies or simply stomiiforms. The scientific name means "''Stomias''-shaped", from ''Stomias'' (the type genus) + the standard fish order suffix "-formes". It ultimately derives from Ancient Greek ''stóma'' (στόμᾶ, "mouth") + Latin ''forma'' ("external form"), the former in reference to the huge mouth opening of these fishes. The earliest stomiiform is ''Paravinciguerria'' from the Cenomanian of Morocco and Italy. D ...

Integrated Taxonomic Information System
The Integrated Taxonomic Information System (ITIS) is an American partnership of federal agencies designed to provide consistent and reliable information on the taxonomy of biological species. ITIS was originally formed in 1996 as an interagency group within the US federal government, involving several US federal agencies, and has now become an international body, with Canadian and Mexican government agencies participating. The database draws from a large community of taxonomic experts. Primary content staff are housed at the Smithsonian National Museum of Natural History and IT services are provided by a US Geological Survey facility in Denver. The primary focus of ITIS is North American species, but many biological groups exist worldwide and ITIS collaborates with other agencies to increase its global coverage. Reference database ITIS provides an automated reference database of scientific and common names for species. it contains over 839,000 scientific names, synonyms, and ...
