Eulimella Scillae
''Eulimella scillae'' is a species of sea snail, a marine gastropod mollusk in the family Pyramidellidae, the pyrams and their allies. Description The white shell is rather solid and polished. Its length measures 9 mm. The teleoconch contains 11 to 12 flatly convex whorls. The last whorls are subangulated on the periphery. Distribution This species occurs in the following locations: at depths between 99 m and 200 m * Azores * Canary Islands * Cape Verdes * European waters (ERMS scope) * Greek Exclusive Economic Zone * Madeira * North Europe * Portuguese Exclusive Economic Zone * Spanish Exclusive Economic Zone * United Kingdom Exclusive Economic Zone * Mauritania Mauritania (; ar, موريتانيا, ', french: Mauritanie; Berber: ''Agawej'' or ''Cengit''; Pulaar: ''Moritani''; Wolof: ''Gànnaar''; Soninke:), officially the Islamic Republic of Mauritania ( ar, الجمهورية الإسلامية ...

Gastropod Shell
The gastropod shell is part of the body of a Gastropoda, gastropod or snail, a kind of mollusc. The shell is an exoskeleton, which protects from predators, mechanical damage, and dehydration, but also serves for muscle attachment and calcium storage. Some gastropods appear shell-less (slugs) but may have a remnant within the mantle, or in some cases the shell is reduced such that the body cannot be retracted within it (semi-slug). Some snails also possess an operculum that seals the opening of the shell, known as the Aperture (mollusc), aperture, which provides further protection. The study of mollusc shells is known as conchology. The biological study of gastropods, and other molluscs in general, is malacology. Shell morphology terms vary by species group. Shell layers The gastropod shell has three major layers secreted by the Mantle (mollusc), mantle. The calcareous central layer, tracum, is typically made of calcium carbonate precipitated into an organic matrix known as c ...

Molluscs Of Madeira
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.

Gastropods Described In 1835
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.

Eulimella
''Eulimella'' is a genus of sea snails, marine gastropod mollusks in the family Pyramidellidae, the pyrams and their allies.Bouchet, P.; Gofas, S. (2011). ''Eulimella'' Forbes & M'Andrew, 1846. Accessed through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&id=138404 on 27 August 2012 The subgenus name ''Ptycheulimella'' Sacco, 1892 or Turbonilla (Ptycheulimella) Sacco, 1892 has been used to describe species whose shells show a weak fold on the columella and frequently a brownish spiral band. Van Aartsen decided not to subdivide ''Eulimella'' s.l. because of the uncertainty of the identification of the type species of this subgenus compared with ''Tornatella pyramidata'' Deshayes, 183 Description Many species are poorly known. The elongated, turriculate shells are small, mostly under 1 cm. They are somewhat glossy and show no sculpture except a few microscopic growth lines. The teleoconch has numerous whorls. The apex is sinistral ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mauritania
Mauritania (; ar, موريتانيا, ', french: Mauritanie; Berber languages, Berber: ''Agawej'' or ''Cengit''; Pulaar language, Pulaar: ''Moritani''; Wolof language, Wolof: ''Gànnaar''; Soninke language, Soninke:), officially the Islamic Republic of Mauritania ( ar, الجمهورية الإسلامية الموريتانية), is a sovereign country in West Africa. It is bordered by the Atlantic Ocean to the west, Western Sahara to Mauritania–Western Sahara border, the north and northwest, Algeria to Algeria–Mauritania border, the northeast, Mali to Mali–Mauritania border, the east and southeast, and Senegal to Mauritania–Senegal border, the southwest. Mauritania is the 11th-largest country in Africa and the 28th-largest in the world, and 90% of its territory is situated in the Sahara. Most of its population of 4.4 million lives in the temperate south of the country, with roughly one-third concentrated in the Capital city, capital and largest city, Nouakchott, loca ...

Canary Islands
The Canary Islands (; es, Canarias, ), also known informally as the Canaries, are a Spanish autonomous community and archipelago in the Atlantic Ocean, in Macaronesia. At their closest point to the African mainland, they are west of Morocco. They are the southernmost of the autonomous communities of Spain. The islands have a population of 2.2 million people and they are the most populous special territory of the European Union. The seven main islands are (from largest to smallest in area) Tenerife, Fuerteventura, Gran Canaria, Lanzarote, La Palma, La Gomera, and El Hierro. The archipelago includes many smaller islands and islets, including La Graciosa, Alegranza, Isla de Lobos, Montaña Clara, Roque del Oeste, and Roque del Este. It also includes a number of rocks, including those of Salmor, Fasnia, Bonanza, Garachico, and Anaga. In ancient times, the island chain was often referred to as "the Fortunate Isles". The Canary Islands are the southernmost regio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
