Notocochlis Chemnitzii
''Notocochlis chemnitzii'', or Chemnitz' moon snail, is a species of gastropod mollusc. It was first described to science in 1840 by Ludwig Karl Georg Pfieffer. The animal is likely named after conchologist Johann Hieronymus Chemnitz. Description The shell is smooth. There are four to five whorls with a short spire. It is grayish-blue to grayish-yellow, with arrow-shaped bands of brown and white. Some individuals may have a white band on the upper part of their whorls. The interior of the shell is brown. The shell has a maximum length of 33 mm (1.3 inches) and a diameter of 31 mm. The operculum is white and smooth. Distribution These snails are found from Baja California Sur to Peru, including the Gulf of California. This species is also found in the Galapagos Islands. They live in the intertidal zone, down to 3 meters (10 feet) deep, on sand and mud flats. Life history This moon snail preys on small bivalves. It is actively mobile, hunting on soft seabeds f ...

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] |
Gastropoda
The gastropods (), commonly known as snails and slugs, belong to a large taxonomic class of invertebrates within the phylum Mollusca called Gastropoda (). This class comprises snails and slugs from saltwater, from freshwater, and from land. There are many thousands of species of sea snails and slugs, as well as freshwater snails, freshwater limpets, and land snails and slugs. The class Gastropoda 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 Late Cambrian. , 721 families of gastropods are known, of which 245 are extinct and appear only in the fossil record, while 476 are currently extant with or without a fossil record. Gastropoda (previously known as univalves and sometimes spelled "Gasteropoda") are a major part of the phylum Mollusca, and are the most highly diversified class in the phylum, with 65,000 to 80,000 living snail and slug species.

Mollusca
Mollusca is the second-largest phylum of invertebrate animals after the Arthropoda, the members of which are known as molluscs or mollusks (). Around 85,000 extant species of molluscs are recognized. The number of fossil species is estimated between 60,000 and 100,000 additional species. 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. Numerous molluscs also live in freshwater and terrestrial habitats. They are highly diverse, not just in size and anatomical structure, but also in behaviour and habitat. 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 invertebrate species.

Ludwig Karl Georg Pfeiffer
Ludwig Karl Georg Pfeiffer, also known as Louis Pfeiffer (4 July 1805 – 2 October 1877), was a German physician, botany, botanist and conchology, conchologist. Early life, Education & Medical Career Louis Pfeiffer was born in Cassel, the eldest son of the jurist Burkhard Wilhelm Pfeiffer and his wife Louise (née Harnier). Pfeiffer received his primary education in the Friedrichsgymnasium Kassel, Cassel Lyceum, where he distinguished himself academically, and by the age of fifteen was already at the top of his class. In 1820, political tensions forced his father to relocate the family to Lübeck, but Louis continued to excel, reaching the top of his class there as well. At the age of sixteen, Pfeiffer entered into university to study medicine, first at the University of Göttingen, and finally at the University of Marburg, where he studied under such prominent scientists as Georg Wilhelm Franz Wenderoth and :de:Ernst Daniel August Bartels, Ernst Daniel August Bartels, graduating ...

Conchology
Conchology () is the study of mollusc shells. Conchology is one aspect of malacology, the study of molluscs; however, malacology is the study of molluscs as whole organisms, whereas conchology is confined to the study of their shells. It includes the study of land and freshwater mollusc shells as well as seashells and extends to the study of a gastropod's operculum. Conchology is now sometimes seen as an archaic study, because relying on only one aspect of an organism's morphology can be misleading. However, a shell often gives at least some insight into molluscan taxonomy, and historically the shell was often the only part of exotic species that was available for study. Even in current museum collections it is common for the dry material (shells) to greatly exceed the amount of material that is preserved whole in alcohol. Conchologists mainly deal with four molluscan orders: the gastropods (snails), bivalves (clams), Polyplacophora (chitons) and Scaphopoda (tusk shells). Ce ...

Johann Hieronymus Chemnitz
Johann Hieronymus Chemnitz (10 October 1730, Magdeburg – 12 October 1800, Copenhagen) was a German clergyman and a conchologist. From 1759 to 1768 he was Chaplain of the Danish Embassy in Vienna, then garrison Chaplain in Helsingør and Copenhagen. Johann Chemnitz continued the work of Friedrich Wilhelm Martini (1729–1778), ''Neues systematisches Conchylien-Cabinet''. He added to the three volumes previously published eight new volumes in 1779 and 1795. Although neither of the two authors use the binomial system, they are regarded as the authors of many species which were first described in this work. Chemnitz used many specimens from cabinet of curiosities of the king of Denmark whose conservator was Lorenz Spengler (1720–1807). Chemnitz began with a collection of half shells before collecting whole shells. His patron was Christian Hee Hwass (1731–1803). The 5th volume describes and portrays many shells from New Zealand and some from Australia collected during Cook ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Baja California Sur
Baja California Sur (; 'South Lower California'), officially the Free and Sovereign State of Baja California Sur ( es, Estado Libre y Soberano de Baja California Sur), is the least populated state and the 31st admitted state of the 32 federal entities which comprise the 31 States of Mexico. It is also the ninth-largest Mexican state in terms of area. Before becoming a state on 8 October 1974, the area was known as the ''El Territorio Sur de Baja California'' ("South Territory of Lower California"). It has an area of , or 3.57% of the land mass of Mexico, and occupies the southern half of the Baja California Peninsula, south of the 28th parallel, plus the uninhabited Rocas Alijos in the Pacific Ocean. It is bordered to the north by the state of Baja California, to the west by the Pacific Ocean, and to the east by the Gulf of California. The state has maritime borders with Sonora and Sinaloa to the east, across the Gulf of California. The state is home to the tourist resorts ...

Gulf Of California
The Gulf of California ( es, Golfo de California), also known as the Sea of Cortés (''Mar de Cortés'') or Sea of Cortez, or less commonly as the Vermilion Sea (''Mar Bermejo''), is a marginal sea of the Pacific Ocean that separates the Baja California Peninsula from the Mexico, Mexican mainland. It is bordered by the states of Baja California, Baja California Sur, Sonora, and Sinaloa with a coastline of approximately . Rivers that flow into the Gulf of California include the Colorado River, Colorado, Fuerte River, Fuerte, Mayo River (Mexico), Mayo, Sinaloa River, Sinaloa, Sonora River, Sonora, and the Yaqui River, Yaqui. The surface of the gulf is about . Maximum depths exceed because of the complex geology, linked to plate tectonics. The gulf is thought to be one of the most diverse seas on Earth and is home to more than 5,000 species of micro-invertebrates. Parts of the Gulf of California are a UNESCO World Heritage Site.

Galápagos Islands
The Galápagos Islands (Spanish: , , ) are an archipelago of volcanic islands. They are distributed on each side of the equator in the Pacific Ocean, surrounding the centre of the Western Hemisphere, and are part of the Republic of Ecuador. Located west of continental Ecuador, the islands are known for their large number of endemic species that were studied by Charles Darwin during the second voyage of HMS ''Beagle''. His observations and collections contributed to the inception of Darwin's theory of evolution by means of natural selection. The Galápagos Islands and their surrounding waters form the Galápagos Province of Ecuador, the Galápagos National Park, and the Galápagos Marine Reserve. The principal language on the islands is Spanish. The islands have a population of slightly over 25,000. The first recorded visit to the islands happened by chance in 1535, when Fray Tomás de Berlanga, the Bishop of Panamá, was surprised to find this undiscovered land on a vo ...
