Protatlanta Souleyeti
''Protatlanta souleyeti'' is a species of sea snail, a holoplanktonic marine gastropod mollusk in the family Atlantidae. ''Protatlanta souleyeti'' is the type species on the genus ''Protatlanta''. It is considered to be the only Recent species on the genus. The specific name ''souleyeti'' is in honor of French malacologist Louis François Auguste Souleyet. Description The maximum recorded shell length is 2 mm.Welch J. J. (2010). "The "Island Rule" and Deep-Sea Gastropods: Re-Examining the Evidence". '' PLoS ONE'' 5(1): e8776. . Some of the fossil specimens preserve a pinkish colour of the larval shells. The protoconch is naticoid in shape and has approximately 3¼ whorls. Most specimens have two thin spirals above the periphery, visible in apical view, and a third such spiral below the periphery, which separates the base of the protoconch and becomes covered by subsequent whorls. The described ornament can be fairly constant, but some specimens were found in which thes ... [...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.

Anda, Pangasinan
Anda, officially the Municipality of Anda ( pag, Baley na Anda; ilo, Ili ti Anda; tgl, Bayan ng Anda), is a 3rd class municipality in the province of Pangasinan, Philippines. According to the 2020 census, it has a population of 41,548 people. The municipality consists primarily of Cabarruyan Island (also known as Anda Island), as well as minor surrounding islets. Because of Anda's proximity near the Hundred Islands, a popular tourist destination for its caves and beaches, it is the so-called "Mother of the Hundred Islands." Anda is from Lingayen and from Manila. History On the north-west portion of Lingayen Gulf lies a group of islands which comprise the territory of Anda. Before the middle of the nineteenth century, the islands which comprise the municipality were uninhabited. Only occasionally did seafarers and fishermen use the coast as havens. Andres de la Cruz Cacho, fondly called in Bolinao as Andales Kulayo, discovered a vast tract of land suitable for grazing and ...

Cainozoic
The Cenozoic ( ; ) is Earth's current geological era, representing the last 66million years of Earth's history. It is characterised by the dominance of mammals, birds and flowering plants, a cooling and drying climate, and the current configuration of continents. It is the latest of three geological eras since complex life evolved, preceded by the Mesozoic and Paleozoic. It started with the Cretaceous–Paleogene extinction event, when many species, including the non-avian dinosaurs, became extinct in an event attributed by most experts to the impact of a large asteroid or other celestial body, the Chicxulub impactor. The Cenozoic is also known as the Age of Mammals because the terrestrial animals that dominated both hemispheres were mammalsthe eutherians (placentals) in the northern hemisphere and the metatherians (marsupials, now mainly restricted to Australia) in the southern hemisphere. The extinction of many groups allowed mammals and birds to greatly diversify so that l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Conchiolin
Conchiolins (sometimes referred to as conchins) are complex proteins which are secreted by a mollusc's outer epithelium (the mantle). These proteins are part of a matrix of organic macromolecules, mainly proteins and polysaccharides, that assembled together form the microenvironment where crystals nucleate and grow. This organic matrix also holds and binds to the crystals of aragonite which give such shells their stiffness. The ions necessary to form calcium carbonate are also secreted by the mantle, but it is the tailored environment created by the organic matrix which causes aragonite (rather than calcite) crystals to nucleate, in much the same way that collagen nucleates hydroxyapatite crystals. Conchiolin serves as a relatively flexible, crack-deflecting matrix for the mineral aggregate particles; its strength and the strong bonding of perlucin can in some cases (such as in the formation of nacre) give the finished material an impressive level of toughness. As well a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gulf Of Naples
The Gulf of Naples (), also called the Bay of Naples, is a roughly 15-kilometer-wide (9.3 mi) gulf located along the south-western coast of Italy (province of Naples, Campania region). It opens to the west into the Mediterranean Sea. It is bordered on the north by the cities of Naples and Pozzuoli, on the east by Mount Vesuvius, and on the south by the Sorrento Peninsula and the main town of the peninsula, Sorrento. The Peninsula separates the Gulf of Naples from the Gulf of Salerno, which includes the Amalfi Coast. The islands of Capri, Ischia and Procida are located in the Gulf of Naples. The area is a tourist destination, with the seaside Roman ruins of Pompeii and Herculaneum at the foot of Mount Vesuvius (destroyed in the AD 79 eruption of Vesuvius), along the north coast. Along with the island of Ischia and gulfs of Pozzuoli and Gaeta, local waters are home to varieties of whales and dolphins including fin and sperm whales.Mussi B.. Miragliuolo A.. Monzini E.. B ...

Naticoidea
Naticidae, common name moon snails or necklace shells, is a family of medium to large-sized predatory sea snails, marine gastropod molluscs in the clade Littorinimorpha. The shells of the species in this family are mostly globular in shape. Naticidae is the only family in the superfamily Naticoidea. It has been estimated that worldwide there are about 260–270 recent species of naticid snails. This group is assumed to have originated in the late Triassic or in the early Jurassic. Members of this family can be recognized by the shape of their shells, distinct appearance, or by their predatory behavior. Distribution Naticids are widely distributed and occur worldwide. The greatest diversity of both species and genera is found in tropical regions. Even so, naticid snails are also plentiful in temperate, Arctic and Antarctic waters. Habitat Moon snails live on sandy substrates, at a great variety of depths depending on the species (from the intertidal zone to thousands o ...

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 ...

Louis François Auguste Souleyet
Louis François Auguste Souleyet (8 January 1811 – 7 October 1852) was a French zoologist, malacologist and naval surgeon. Souleyet was naturalist-surgeon on the voyage of ''La Bonite'', which circumnavigated the globe between February 1836 and November 1837 under Auguste Nicolas Vaillant (1793–1858). In the Pacific he studied marine molluscs. After the death of Joseph Fortuné Théodore Eydoux (1802–1841), Souleyet completed the zoological section of the voyage's official report in 1852. Souleyet died of yellow fever in Martinique in 1852. He named a number of marine molluscs and fish, but most of his new taxa were validated two years earlier by John Edward Gray, who Latinized all vernacular names published earlier in an undated (1842 ?) atlas by Eydoux & Souleyet. He is himself commemorated in the scientific name of the streak-headed woodcreeper, ''Lepidocolaptes souleyetii'', named for him by DesMurs and in the Heteropod '' Protatlanta souleyeti'' by Edgar A. Smith in 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Specific Name (zoology)
In zoological nomenclature, the specific name (also specific epithet or species epithet) is the second part (the second name) within the scientific name of a species (a binomen). The first part of the name of a species is the name of the genus or the generic name. The rules and regulations governing the giving of a new species name are explained in the article species description. For example, the scientific name for humans is ''Homo sapiens'', which is the species name, consisting of two names: ''Homo'' is the " generic name" (the name of the genus) and ''sapiens'' is the "specific name". Historically, ''specific name'' referred to the combination of what are now called the generic and specific names. Carl Linnaeus, who formalized binomial nomenclature, made explicit distinctions between specific, generic, and trivial names. The generic name was that of the genus, the first in the binomial, the trivial name was the second name in the binomial, and the specific the proper term for ...
