Raphitoma Echinata
''Raphitoma echinata'' is a species of sea snail, a marine gastropod mollusk in the family Raphitomidae. ;Subspecies: * ''Raphitoma echinata pumila'' Monterosato, 1890 Description The shell length varies between 12 mm and 20 mm. Distribution This species is distributed in the Mediterranean Sea along Apulia, Greece, and the Balearic Islands The Balearic Islands ( es, Islas Baleares ; or ca, Illes Balears ) are an archipelago in the Balearic Sea, near the eastern coast of the Iberian Peninsula. The archipelago is an autonomous community and a province of Spain; its capital is .... They are also found north of the Hebrides and in the North Sea. As they occupy the coasts and the former Doggerland, it can be ascertained that Raphitoma echinata enjoy shallow waters. References * Gofas, S.; Le Renard, J.; Bouchet, P. (2001).

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] |
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. Anatomy Sea snails are a very large group of animals and a very diverse one. Most snails that live in salt water respire using a gill or gills; a few species, though, have a lung, are intertidal, and are active only at low tide when they can move around in the air. These air-breathing species includ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 opini ...

Raphitomidae
Raphitomidae is a family of small to medium-sized sea snails, marine gastropod mollusks in the superfamily Conoidea.Bouchet P. & Rocroi J.-P. (Ed.) (2005). "Classification and nomenclator of gastropod families". ''Malacologia'' 47(1-2). . 397 pp. Bouchet, Kantor ''et al''. elevated in 2011 the subfamily Raphitominae (which at that point had been placed in the family Conidae) to the rank of family. This was based on a cladistical analysis of shell morphology, radular characteristics, anatomical characters, and a dataset of molecular sequences of three gene fragments. The family was found to be monophyletic. Description The Raphitomidae is the largest, most diverse and most variable taxon in the Conoidea, with the greatest number of species and the largest ecological range (from the tropics to the pole) and largest vertical range (intertidal to hadal depths). The shells of species in the Raphitomidae are very variable in shape (buccinoid to ovate, elongate-fusiform, or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Balearic Islands
The Balearic Islands ( es, Islas Baleares ; or ca, Illes Balears ) are an archipelago in the Balearic Sea, near the eastern coast of the Iberian Peninsula. The archipelago is an autonomous community and a province of Spain; its capital is Palma. The 2007 Statute of Autonomy designates the Balearic Islands as one of the ''nationalities'' of Spain. The official languages of the Balearic Islands are Catalan and Spanish. Its four largest islands are Mallorca, Menorca, Ibiza, and Formentera. Many of its minor islands and islets are close to the larger islands, including Cabrera, Dragonera, and S'Espalmador. The islands have a Mediterranean climate, and the four major islands are all popular tourist destinations. Ibiza, in particular, is known as an international party destination, attracting many of the world's most popular DJs to its nightclubs. The islands' culture and cuisine are similar to those of the rest of Spain but have their own distinctive features. Etymology ...

Hebrides
The Hebrides (; gd, Innse Gall, ; non, Suðreyjar, "southern isles") are an archipelago off the west coast of the Scottish mainland. The islands fall into two main groups, based on their proximity to the mainland: the Inner and Outer Hebrides. These islands have a long history of occupation (dating back to the Mesolithic period), and the culture of the inhabitants has been successively influenced by the cultures of Celtic-speaking, Norse-speaking, and English-speaking peoples. This diversity is reflected in the various names given to the islands, which are derived from the different languages that have been spoken there at various points in their history. The Hebrides are where much of Scottish Gaelic literature and Gaelic music has historically originated. Today, the economy of the islands is dependent on crofting, fishing, tourism, the oil industry, and renewable energy. The Hebrides have less biodiversity than mainland Scotland, but a significant number of seals an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Doggerland
Doggerland was an area of land, now submerged beneath the North Sea, that connected Britain to continental Europe. It was flooded by rising sea levels around 6500–6200 BCE. The flooded land is known as the Dogger Littoral. Geological surveys have suggested that it stretched from what is now the east coast of Great Britain to what are now the Netherlands, the western coast of Germany and the Danish peninsula of Jutland. It was probably a rich habitat with human habitation in the Mesolithic period,Patterson, W, "Coastal Catastrophe" (paleoclimate research document), University of Saskatchewan although rising sea levels gradually reduced it to low-lying islands before its final submergence, possibly following a ts ...

Raphitoma
''Raphitoma'' is a genus of sea snails, marine gastropod mollusks in the family Raphitomidae. The type species ''Pleurotoma hystrix'' Cristofori and Jan, 1832 is a nomen nudum. It has been validated by Bellardi, 1847 as “''Pleurotoma histrix'' Jan.” Distribution This genus occurs in European waters, in the northern part of the Mediterranean Sea, and in the Atlantic Ocean off Cape Verde, West Africa and Angola. Taxonomy history The genus ''Raphitoma'' was created in 1847 by Luigi Bellardi (1818-1889) in his "Monographie des Pleurotomes fossiles du Piémont" for species in different groups without operculum. ''Raphitoma'' now contains many species formerly assigned to ''Pleurotoma'' Lamarck, 1799, ''Clathurella'' (Carpenter, 1857) and ''Philbertia'' (Monterosato, 1884). ''Philbertia'' was synonymized with ''Raphitoma'' in 1990 because Dr. Philippe Bouchet did not consider valid the subdivision of species into different genera solely on the basis of differences du ...
