Paul Henri Fischer
Paul Henri Fischer (also spelled Paul-Henri Fischer), (7 July 1835 Paris – 29 November 1893) was a French physician, zoologist and paleontologist. He is generally known as Paul Fischer. Biography He studied science and medicine, securing doctorates in both, and became assistant in paleontology at the National Museum of Natural History in Paris. He was made assistant naturalist there in 1872. Beginning in 1856, he was joint editor, with A. C. Bernardi to start with, of the ''Journal de Conchyliologie''. He served several terms as president of the Société Géologique de France and the Société Zoologique de France. In 1880, he was a member of the commission for submarine dredging.

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. 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. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists 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. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
William Adam (malacologist)
William Adam (27 Januari 1909, The Hague – 3 November 1988, Brussels) was a Dutch / Belgian malacologist who specialised in cephalopods. Adam described a number of cuttlefish and bobtail squid species, including ''Euprymna hoylei'', ''Sepia cottoni'', ''Sepia dollfusi'', ''Sepia dubia'', ''Sepia reesi'', ''Sepia sewelli'', ''Sepia thurstoni'', ''Sepia vercoi'', and ''Sepiola knudseni''. Adam was born as the son of Constance Jeannette Barkhuijsen and the merchant sailor William Adam. After his schooling in The Hague he visited Java in 1926-27. Upon his return home he studied biology at Utrecht University, obtaining his PhD in 1933 with a dissertation on terrestrial mollusk glands. He then took a position at the Museum of Natural Sciences in Brussels, where he climbed the ranks. In 1952 he became a Belgian citizen. In 1957 Adam became correspondent of the Royal Netherlands Academy of Arts and Sciences The Royal Netherlands Academy of Arts and Sciences ( nl, Koninklij ...

Louis Joubin
Louis Marie Adolphe Olivier Édouard Joubin (27 February 1861 in Épinal – 24 April 1935 in Paris) was a professor at the Muséum national d'Histoire naturelle in Paris. He published works on nemerteans, chaetognatha, cephalopods, and other molluscs. He served as an assistant to Henri de Lacaze-Duthiers, subsequently becoming director of the laboratories at Banyuls-sur-Mer (1882) and Roscoff (1884). Later on, he became an instructor at the University of Rennes,Prosopo Sociétés savantes and in 1903 succeeded Edmond Perrier as ''chaire des mollusques, des vers et des zoophytes'' at the |
Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. 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 ...

Octopus
An octopus ( : octopuses or octopodes, see below for variants) is a soft-bodied, eight- limbed mollusc of the order Octopoda (, ). The order consists of some 300 species and is grouped within the class Cephalopoda with squids, cuttlefish, and nautiloids. Like other cephalopods, an octopus is bilaterally symmetric with two eyes and a beaked mouth at the center point of the eight limbs. The soft body can radically alter its shape, enabling octopuses to squeeze through small gaps. They trail their eight appendages behind them as they swim. The siphon is used both for respiration and for locomotion, by expelling a jet of water. Octopuses have a complex nervous system and excellent sight, and are among the most intelligent and behaviourally diverse of all invertebrates. Octopuses inhabit various regions of the ocean, including coral reefs, pelagic waters, and the seabed; some live in the intertidal zone and others at abyssal depths. Most species grow quickly, mature ea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...
