Jean-Baptiste Lamarck
Jean-Baptiste Pierre Antoine de Monet, chevalier de Lamarck (1 August 1744 – 18 December 1829), often known simply as Lamarck (; ), was a French naturalist, biologist, academic, and soldier. He was an early proponent of the idea that biological evolution occurred and proceeded in accordance with natural laws. Lamarck fought in the Seven Years' War against Prussia, and was awarded a commission for bravery on the battlefield. Posted to Monaco, Lamarck became interested in natural history and resolved to study medicine. Packard (1901), p. 15. He retired from the army after being injured in 1766, and returned to his medical studies. Lamarck developed a particular interest in botany, and later, after he published the three-volume work ''Flore françoise'' (1778), he gained membership of the French Academy of Sciences in 1779. Lamarck became involved in the Jardin des Plantes and was appointed to the Chair of Botany in 1788. When the French National Assembly founded the Mus� ...

Rodolfo Amando Philippi
Rodolfo Amando (or Rudolph Amandus) Philippi (14 September 1808 – 23 July 1904) was a German–Chilean paleontologist and zoologist. Philippi contributed primarily to malacology and paleontology. His grandson, Rodulfo Amando Philippi Bañados (1905-1969), was also a zoologist and in order to avoid confusion in zoological nomenclature, the elder is referred to as "Philippi rumwiede to distinguish him from his grandson "Philippi añados. Early life Philippi was born in Charlottenburg, Berlin to Johann Wilhelm Eberhard Philippi, a Prussian government auditor, and his third wife Maria Anna Krumwiede (m. 1806). The father had five children from two earlier marriages and Philippi was the eldest from the third marriage. In 1818, Philippi, his younger brother Bernhard Eunom (1811–1852) and their mother went to Yverdon-les-Bains, Switzerland, where they were educated at the Pestalozzian Institute founded by Johann Heinrich Pestalozzi (1746–1827). The teaching included the use ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hombron
Jacques Bernard Hombron (1798–1852) was a French naval surgeon and naturalist. Hombron served on the French voyage of the ''Astrolabe'' and ''Zélée'' between 1837 and 1840 to investigate the perimeter of Antarctica.

Honoré Jacquinot
Honoré Jacquinot (1 August 1815 in Moulins-Engilbert - 22 May 1887 in Nevers) was a French surgeon and zoologist. Jacquinot was the younger brother of the naval officer Charles Hector Jacquinot, and sailed with him as a surgeon and naturalist on ''La Zelée'' on Dumont d'Urville's ''Astrolabe'' expedition (1837–1840). With J. B. Hombron, while en route to the Antarctic and anchored off the coast of New Zealand, he was able to describe and illustrate 15 species of molluscs found in those waters, plus several species of fish and crustacea.

Hermann Strebel (malacologist)
Hermann Wilhelm Strebel ( Hamburg, 1 January 1834 – Hamburg, 6 November 1914) was a merchant, ethnologue and a malacologist from Germany and Mexico. Biography He was born on 1 January 1834 in Hamburg as the youngest of four brothers. Through his school teacher he became interested in the study of snails and their shells On 13 August 1848, he left for Veracruz (city), Veracruz in Mexico. Under the supervision of his eldest brother he became an apprentice in a factory. He would stay in Mexico for the next twenty years. He survived a shipwreck off the coast of Yucatán (peninsula), Yucatán. Between 1852 and 1867 he worked as a merchant for German exporters of manufactured goods. During this time he began under the guidance of his friend Carl Hermann Berendt collecting shells of native snails, which would constitute the basis of his collection. At this time, he began a lively exchange with German and American malacologists. He was also introduced by Berendt to zoology and archeolog ...

Species
In biology, a species is the basic unit of Taxonomy (biology), 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 reproduction, produce Fertility, fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), 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 binomial nomenclature, 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 specifi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sea Snail
Sea snail is a common name for slow-moving marine gastropod molluscs, usually with visible external shells, such as whelk or abalone. They share the taxonomic class Gastropoda with slugs, which are distinguished from snails primarily by the absence of a visible shell. Definition Determining whether some gastropods should be called sea snails is not always easy. Some species that live in brackish water (such as certain neritids) can be listed as either freshwater snails or marine snails, and some species that live at or just above the high tide level (for example species in the genus '' Truncatella'') are sometimes considered to be sea snails and sometimes listed as land snails A land snail is any of the numerous species of snail that live on land, as opposed to the sea snails and freshwater snails. ''Land snail'' is the common name for terrestrial gastropod mollusks that have shells (those without shells are known .... Anatomy Sea snails are a very large group o ...

Gastropod
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.

Mollusk
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.

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 opi ...

Muricidae
Muricidae is a large and varied taxonomic family of small to large predatory sea snails, marine gastropod mollusks, commonly known as murex snails or rock snails. With about 1,600 living species, the Muricidae represent almost 10% of the Neogastropoda. Additionally, 1,200 fossil species have been recognized.Merle, D., Garrigues, B. & Pointier, J.-P. (2011). ''Fossil and Recent Muricidae of the World, Part Muricinae''. 648 pp., 182 colour plates, ConchBooks, Hackenheim. . Numerous subfamilies are recognized, although experts disagree about the subfamily divisions and the definitions of the genera. Many muricids have unusual shells which are considered attractive by shell collectors and by interior designers. Shell description Muricid shells are variably shaped, generally with a raised spire and strong sculpture with spiral ridges and often axial varices (typically three or more varices on each whorl), also frequently bearing spines, tubercles, or blade-like processes.
