Franz Hermann Troschel
Franz Hermann Troschel (10 October 1810 – 6 November 1882) was a German zoologist born in Spandau. He studied mathematics and natural history at the University of Berlin, where he was awarded his doctorate in 1834.Beolens, Bo; Watkins, Michael; Grayson, Michael (2011). ''The Eponym Dictionary of Reptiles''. Baltimore: Johns Hopkins University Press. xiii + 296 pp. . ("Troschel", p. 268). From 1840 to 1849 he was an assistant to Martin Lichtenstein at the Natural History Museum, Berlin, Natural History Museum of Berlin. In 1849 he became a professor of zoology and natural history at the University of Bonn. In 1851 he became a member of the Academy of Sciences Leopoldina. ''Deutschen Akademie der Naturforscher Leopoldina''. Troschel is remembered for the identification and classification o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stefano Delle Chiaje
Stefano Delle Chiaje (25 April 1794 – 18 December 1860) was an Italian zoologist, botanist, anatomist and physician. Delle Chiaje studied medicine in Naples, where he was a pupil of Giuseppe Saverio Poli. Together they started compiling books on the bivalves and the gastropod molluscs of the Kingdom of the Two Sicilies. He later taught pathology and performed research in the field of malacology. He erected the genus of nemertean worms ''Polia'', naming it in honour of Poli, and described ''Polia lineata'' and ''Polia siphunculus''. The latter has since been synonymised with '' Cerebratulus marginatus'', but Delle Chiaje's description shows an understanding of the animal's anatomy and recognition of its constituent parts that was missing among many of his contemporaries. He made a study of the skeletons and detached bones found during the excavations of the buried city of Pompeii, making deductions on the health of the population, their characters and occupations, the types of ...

André Étienne D'Audebert De Férussac
Baron André Étienne Justin Pascal Joseph François d'Audebert de Férussac (30 December 1786 – 21 January 1836) was a French naturalist best known for his studies of molluscs. (Two of his given names are sometimes spelt Just or Juste instead of Justin, and d'Audibert, d'Audebard, or d'Audeberd instead of "d'Audebert".) He was born in Chartron, near Lauzerte in the province of Quercy (now in Tarn-et-Garonne), the son of Jean Baptiste Louis d'Audibert de Férussac and Marie Catherine Josèphe de Rozet, and was professor of geography and statistics at the École d'état-major in Paris. Taxa Férussac named and described numerous taxa of gastropods, including: * '' Cochlodina'' Férussac, 1821, a land snail genus * ''Helicostyla'' Férussac, 1821, a land snail genus Various other taxa were named in honor of him, including: * Ferussaciidae Bourguignat, 1883,Bourguignat, J.

Alcide D'Orbigny
Alcide Charles Victor Marie Dessalines d'Orbigny (6 September 1802 – 30 June 1857) was a French naturalist who made major contributions in many areas, including zoology (including malacology), palaeontology, geology, archaeology and anthropology. D'Orbigny was born in Couëron (Loire-Atlantique), the son of a ship's physician and amateur naturalist. The family moved to La Rochelle in 1820, where his interest in natural history was developed while studying the marine fauna and especially the microscopic creatures that he named "foraminiferans". In Paris he became a disciple of the geologist Louis Cordier, Pierre Louis Antoine Cordier (1777–1861) and Georges Cuvier. All his life, he would follow the theory of Cuvier and stay opposed to Lamarckism. South American era D'Orbigny travelled on a mission for the Paris Museum, in South America between 1826 and 1833. He visited Venezuela, Colombia, Ecuador, Peru, Bolivia, Chile, Argentina, Paraguay, and Brazil, and returned to Franc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Octopus
An octopus (: octopuses or octopodes) 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 centre point of the eight limbs. An octopus can radically deform its shape, enabling it to squeeze through small gaps. They trail their appendages behind them as they swim. The siphon is used for respiration and locomotion (by water jet propulsion). Octopuses have a complex nervous system and excellent sight, and are among the most intelligent and behaviourally diverse invertebrates. Octopuses inhabit various ocean habitats, including coral reefs, pelagic waters, and the seabed; some live in the intertidal zone and others at abyssal depths. Most species grow quickly, mature early, and are short-lived. In most species, the male uses a speciall ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Family (biology)
Family (, : ) 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". The delineation of what constitutes a family—or whether a described family should be acknowledged—is established and decided upon by active taxonomists. There are not strict regulations for outlining or acknowledging a family, yet in the realm of plants, these classifications often rely on both the vegetative and reproductive characteristics of plant species. Taxonomists frequently hold varying perspectives on these descriptions, leading to a lack of widespread consensus within the scientific community ...

Mark Norman (marine Biologist)
Mark Douglas Norman (1960s to present) is a scientist living in southern Australia. He works as a Chief Conservation Scientist with Parks Victoria. Prior to 2016 he worked as a curator and marine biologist through the University of Melbourne and Museum Victoria. For over a decade in this role, Norman worked exclusively with cephalopods and was a leading scientist in the field, having discovered over 150 new species of octopuses.
