Gérard Paul Deshayes
Gérard Paul Deshayes (; 13 May 1795 – 9 June 1875) was a French geologist and conchologist. Career He was born in Nancy, his father at that time being professor of experimental physics in the École Centrale of the département Meurthe He studied medicine in Strasbourg, and afterwards took the degree of ''bachelier ès lettres'' in Paris in 1821; but he abandoned the medical profession in order to devote himself to natural history. For some time he gave private lessons on geology, and subsequently became professor of natural history in the Muséum National d'Histoire Naturelle. He was distinguished for his researches on the fossil mollusca of the Paris Basin and of other areas Cenozoic cover. His studies on the relations of the fossil to the recent species led him as early as 1829 to conclusions somewhat similar to those arrived at by Lyell, to whom Deshayes rendered much assistance in connection with the classification of the, then, Tertiary system into Eocene, Miocene a ...

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. The anatomy, behavior, feeding, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Mangeliidae
Mangeliidae is a monophyletic family of small to medium-sized, predatory sea snails, marine gastropod mollusks in the superfamily Conoidea. Bouchet, P. (2011). Mangeliidae P. Fischer, 1883. In: MolluscaBase (2016). Accessed through: World Register of Marine Species at http://marinespecies.org/aphia.php?p=taxdetails&id=153853 on 2017-02-23Bouchet P. & Rocroi J.-P. (Ed.) (2005). "Classification and nomenclator of gastropod families". '' Malacologia'' 47(1-2). . 397 pp. Prior to 2011, both the subfamilies Mangeliinae and Oenopotinae had been placed in the family Conidae. In 2011, Bouchet, Kantor ''et al'' merged the two subfamilies into one taxon, which they elevated to the rank of family. This was based on anatomical characters and a dataset of molecular sequences of three gene fragments. Mangeliidae is a sister-clade to the family Raphitomidae As with their relatives in the family Conidae, species in the family Mangelidae use potent venoms to catch their prey. Through th ...

Mangelia Attenuata
''Mangelia attenuata'' is a species of sea snail, a marine gastropod mollusk in the family Mangeliidae. Description The shell size varies between 5 mm and 13 mm. The shell has nine whorls. Each whorl contains nine ribs, narrow, flexuous, with wider interspaces, spirally slightly and finely striate. The narrow aperture is long. The siphonal canal is short and broad. Its color is pale tawny, the upper part and middle of the body whorl often banded, or the lower half of the body whorl darker colored, sometimes there are several narrow revolving chestnut lines.

Portugal
Portugal, officially the Portuguese Republic, In recognized minority languages of Portugal: :* mwl, República Pertuesa is a country located on the Iberian Peninsula, in Southwestern Europe, and whose territory also includes the Macaronesian archipelagos of the Azores and Madeira. It features the westernmost point in continental Europe, its mainland west and south border with the North Atlantic Ocean and in the north and east, the Portugal-Spain border, constitutes the longest uninterrupted border-line in the European Union. Its archipelagos form two autonomous regions with their own regional governments. On the mainland, Alentejo region occupies the biggest area but is one of the least densely populated regions of Europe. Lisbon is the capital and largest city by population, being also the main spot for tourists alongside Porto, the Algarve and Madeira. One of the oldest countries in Europe, its territory has been continuously settled and fought over since prehistoric tim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mangelia
''Mangelia'' is a large genus of sea snails, marine gastropod mollusks in the family Mangeliidae. The genus has been used for a long time as a wastebasket taxon. There have been many described species, many of which have become synonyms. Among the remaining accepted names a good number are still in doubt and are little known. They are only tentatively placed within the genus ''Mangelia''. This genus was named ''Mangelia'' by Leach and accepted by Risso in 1826. Later, some authors, such as Lovén in 1846, spelled it inadvertently as ''Mangilia'', to honor the Italian malacologist Mangili Giuseppe (1767-1829). This had led to some confusion. Description The shell has a fusiform shape. It is mostly longitudinally ribbed The spire is elongated, turriculated, acuminated. The lip is very finely rugosely denticulated. The lip is thickened and slightly sinuated at the upper part. The siphonal canal is short, more or less truncated. The columella is smooth. The sinus is near the sutur ...
