Eduard Von Martens
Eduard von Martens (18 April 1831 – 14 August 1904) also known as ''Carl'' or ''Karl Eduard von Martens'', was a German zoologist. Born in Stuttgart in 1831, von Martens attended university in University of Tübingen, Tübingen, where he graduated in 1855. He then moved to Berlin, where he would be based for the remainder of his career, both at the Zoological Museum of the Berlin University (from 1855) and, from 1859 on, at the . In 1860, he embarked on the ''Thetis'' expedition of the Prussian expedition to Eastern Asia. When the expedition returned to Europe in 1862, von Martens continued to travel around Maritime Southeast Asia for 15 months. He published the results of the "Thetis" expedition in two volumes, constituting the Zoologischer Theil of the "Preussische Expedition nach Ost-Asien." Vol. ii, consisting of 447 pages and 22 plates, contained a very full account of the land molluscs. Back in Berlin, von Martens was curator of the malacological and other invertebrate ...

Berlin Society Of Friends Of Natural Science
The Berlin Society of Friends of Natural Science, (Gesellschaft Naturforschender Freunde zu Berlin, in German) (GNF) is a scientific society, one of the most important such societies of the late 18th century. After the Danziger Naturforschenden Gesellschaft, it is the oldest private natural society in Germany. It was founded in 1773 by F.H.W. Martini, and originally was based around 12 experts in the natural sciences who visited each other's collections and built up a collection and library for the society. The society also published a journal, in which great care was taken to publish accurate illustrations. The society exists still, with about 140 members. After a decade of inactivity following the Second World War, it has since been associated with the Free University of Berlin. Early Members * Friedrich Heinrich Wilhelm Martini (1729-1778) * Johann Gottlieb Gleditsch (1714-1786) * Marcus Eliesar Bloch (1723-1799) * Martin Heinrich Klaproth (1743-1817) * Dietrich Ludwig Gusta ...

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] |
Freshwater Snail
Freshwater snails are gastropod mollusks that live in fresh water. There are many different families. They are found throughout the world in various habitats, ranging from ephemeral pools to the largest lakes, and from small seeps and springs to major rivers. The great majority of freshwater gastropods have a gastropod shell, shell, with very few exceptions. Some groups of snails that live in freshwater Respiratory system, respire using gills, whereas Pulmonata, other groups need to reach the surface to breathe air. In addition, some are amphibious and have both gills and a lung (e.g. ''Ampullariidae''). Most feed on algae, but many are detritivores and some are Filter feeding, filter feeders. Freshwater snails are indirectly among the deadliest animals to humans, as they carry parasitic worms that cause schistosomiasis, a disease estimated to kill between 10,000 and 200,000 people annually. There are thousands of known species, and at least 33–38 independent Lineage (evolut ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Operculum (gastropod)
An operculum (; ) is a corneous or calcareous anatomical structure like a trapdoor that exists in many (but not all) groups of sea snails and freshwater snails, and also in a few groups of land snails, including the Helicinidae, Cyclophoridae, Aciculidae, Maizaniidae, Pomatiidae, etc. The operculum is attached to the upper surface of the foot and in its most complete state, it serves as a sort of "trapdoor" to close the aperture (mollusc), aperture of the shell when the soft parts of the animal are retracted. The shape of the operculum varies greatly from one family of gastropods to another. It is fairly often circular, or more or less oval in shape. In species where the operculum fits snugly, its outline corresponds exactly to the shape of the aperture (mollusc), aperture of the shell and it serves to seal the entrance of the shell. Many families have opercula that are reduced in size, and which are not capable of closing the shell aperture. Opercula have sometimes been modifie ...

Gastropod
Gastropods (), commonly known as slugs and snails, belong to a large Taxonomy (biology), taxonomic class of invertebrates within the phylum Mollusca called Gastropoda (). This class comprises snails and slugs from saltwater, freshwater, and from the land. There are many thousands of species of sea snails and sea slug, slugs, as well as freshwater snails, freshwater limpets, land snails and slugs. The class Gastropoda is a diverse and highly successful class of mollusks within the phylum Mollusca. It contains a vast total of named species, second only to the insects in overall number. The fossil history of this class goes back to the Furongian, Late Cambrian. , 721 family (taxonomy), families of gastropods are known, of which 245 are extinct and appear only in the fossil record, while 476 are currently neontology, extant living fossil, with or without a fossil record. Gastropoda (previously known as univalves and sometimes spelled "Gasteropoda") are a major part of the phylum Mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mollusk
Mollusca is a phylum of protostomic invertebrate animals, whose members are known as molluscs or mollusks (). Around 76,000 extant species of molluscs are recognized, making it the second-largest animal phylum after Arthropoda. The number of additional fossil species is estimated between 60,000 and 100,000, and the proportion of undescribed species is very high. Many taxa remain poorly studied. Molluscs are the largest marine phylum, comprising about 23% of all the named marine organisms. They are highly diverse, not just in size and anatomical structure, but also in behaviour and habitat, as numerous groups are freshwater and even terrestrial species. The phylum is typically divided into 7 or 8 taxonomic classes, of which two are entirely extinct. Cephalopod molluscs, such as squid, cuttlefish, and octopuses, are among the most neurologically advanced of all invertebrates—and either the giant squid or the colossal squid is the largest known extant i ...

Semisulcospiridae
Semisulcospiridae, common name semisulcospirids, is a family of freshwater snails, aquatic gilled gastropod mollusks with an operculum, in the superfamily Cerithioidea.MolluscaBase eds. (2021). MolluscaBase. Semisulcospiridae J. P. E. Morrison, 1952. Accessed through: World Register of Marine Species at: http://marinespecies.org/aphia.php?p=taxdetails&id=715954 on 2021-03-08 Semisulcospiridae diversified from the Pleuroceridae about 90 million years ago, in the Cretaceous. Distribution The family Semisulcospiridae occurs in western North America, the Far East of Russia, Korea, Japan, China and Vietnam. Taxonomy The family Semisulcospiridae was introduced as just a name (nomen nudum) by Morrison (1952), without a diagnosis of the taxon. It is a valid taxon however, because its name has been used as valid. 2005 taxonomy According to the taxonomy of Bouchet & Rocroi (2005), Semisulcospiridae was a subfamily within the family Pleuroceridae. 2009 taxonomy The subfamily ...

Type Locality (biology)
In biology, a type is a particular wikt:en:specimen, specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally associated. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set (mathematics), set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the ''International Code of Nomenclature for algae, fungi, and plants'' (ICN), the ...

Mungyeong
Mungyeong (; ) is a Administrative divisions of South Korea, city in North Gyeongsang Province, South Korea. The local government, economy, and transportation networks are all centered in Jeomchon, the principal town. Mungyeong has a lengthy history, and is known today for its various historic and scenic tourist attractions. The city's name means roughly "hearing good news." Recently, development has been somewhat stagnant with the decline of the coal industry. Since the 1990s, the proportion of people who rely on the tourism industry through Mungyeong Saejae has gradually increased. The city of Mungyeong was created after Jeomchon City and rural Mungyeong County were combined in 1995. It is now an urban-rural complex similar to 53 other small and medium-sized cities with a population under 300,000 people in South Korea. History The Mungyeong area is believed to have been controlled by a mixture of Jinhan confederacy, Jinhan and Byeonhan confederacy, Byeonhan states during the ...
