	Wilhelm Moritz Keferstein Wilhelm Moritz Keferstein (7 June 1833, Winsen (Luhe) – 25 January 1870) was a German naturalist. He described a number of reptiles and amphibians for the first time. He originally studied hydraulic engineering in Hanover, later becoming a lecturer and professor of zoology at the University of Göttingen. With zoologist Ernst Ehlers (1835-1925), he wrote ''Zoologische Beiträge gesammelt im Winter 1859/60 in Neapel und Messina...'' in 1861. With Karl Wilhelm von Kupffer (1829-1902) he was co-author of a study on the electric organs of ''Gymnotus'' and ''Mormyrus'' that was published in Henle and Pfeufer's ''Zeitschrift für rationelle Medicin'' (Journal of rational medicine). He also made important contributions to Heinrich Georg Bronn's ''Die Klassen und Ordnungen des Thier-Reichs'' (Classes and Orders of the Animal Kingdom). Keferstein's tree frog is named after him (a species he described in 1868), as is a genus of polychaetes, ''Kefersteinia'' (family Hesionidae). ...

picture info	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 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.Franz Herrmann Troschel ''Deutschen Akademie der Naturforscher Leopoldina''.

picture info	Thysanoteuthis Rhombus ''Thysanoteuthis rhombus'', also known as the diamond squid, diamondback squid, or rhomboid squid, is a large species of squid from the family Thysanoteuthidae which is found worldwide, throughout tropical and subtropical waters. ''T. rhombus'' is given its name for the appearance of the fins that run the length of the mantle. They are a fast growing species with a lifespan of approximately 1 year. The diamond squid is the only cephalopod species known to be monogamous. ''T. rhombus'' often preys on fish and other small cephalopods at varying water depths. This species is commercially fished in Japan, specifically in the Sea of Japan and Okinawa. Description ''Thysanoteuthis rhombus'' are distinguishable by the presence of arms with two series of suckers, whereas the tentacular clubs have four. It lacks photophores. ''T. rhombus'' is named for its fins, which run in equal length along the mantle, giving the appearance of a rhombus. The species is able to grow up to 100 ...

picture info	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 ...

picture info	Taxon 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 Linnaean taxonomy, system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard de Jussieu, Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first mad ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]

picture info	Cephalopod Genera A cephalopod is any member of the molluscan class Cephalopoda ( Greek plural , ; "head-feet") such as a squid, octopus, cuttlefish, or nautilus. These exclusively marine animals are characterized by bilateral body symmetry, a prominent head, and a set of arms or tentacles ( muscular hydrostats) modified from the primitive molluscan foot. Fishers sometimes call cephalopods "inkfish", referring to their common ability to squirt ink. The study of cephalopods is a branch of malacology known as teuthology. Cephalopods became dominant during the Ordovician period, represented by primitive nautiloids. The class now contains two, only distantly related, extant subclasses: Coleoidea, which includes octopuses, squid, and cuttlefish; and Nautiloidea, represented by '' Nautilus'' and '' Allonautilus''. In the Coleoidea, the molluscan shell has been internalized or is absent, whereas in the Nautiloidea, the external shell remains. About 800 living species of cephalopods have been ...
