Gérard Paul Deshayes
Gérard Paul Deshayes (; 13 May 1795 – 9 June 1875) was a French geologist and conchologist. Career He was born in Nancy, France, Nancy, his father at that time being professor of experimental physics in the École Centrale of the département in France, département Meurthe Department, 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 Charles Lyell, Lyell, to whom Deshayes rendered much assistance in connection with th ...

San Lorenzo Island (Peru)
San Lorenzo Island is the largest island of Peru. The island is in the Pacific Ocean near the port of Callao and measures .INEI, Compendio Estadistica 2007, page 24–25. Sovereignty rights San Lorenzo Island was incorporated in 1899 as territory of the Constitutional Province of Callao by decree of President Andrés Avelino Cáceres Dorregaray. The island was seized by the coup d'état government of Leguía y Salcedo and subsequently adoled out to navy sequestration in 1926. Under the unique status that Callao holds as Peru's only constitutionally formed province/region and without a change of status quo tilted in favor of a republic under civilian control, resolution of conflict over de facto vs de jure land use of San Lorenzo Island remains for global opinion and Peru's Supreme Court to resolve. Access , San Lorenzo is not open to the public. It is a restricted zone controlled by the Marina de Guerra del Perú; in rare cases, specialized professionals (archaeologists, ...

Edible Molluscs
An edible item is any item that is safe for humans to eat. "Edible" is differentiated from "eatable" because it does not indicate how an item tastes, only whether it is fit to be eaten. Nonpoisonous items found in nature – such as some mushrooms, insects, seaweed, and so forth – are referred to as edible. Processed items that normally are not ingested but are specially manufactured to be so, like edible underwear or edible packaging, are also labeled as edible. Edible items in nature It is estimated that approximately half of about 400,000 plant species on earth are edible, yet ''Homo sapiens'' consume only about 200 plant species, because these are the simplest to domesticate. Edible plants found in nature include certain types of mushrooms, flowers, seeds, berries, seaweed, and cacti. Being able to identify the versions of these plants that are safe to eat is an important survival skill. Many animals are also edible, including domesticated livestock as well as wild insect ...

Chiton Granosus
Chitons () are marine molluscs of varying size in the class Polyplacophora (), formerly known as Amphineura. About 940 extant and 430 fossil species are recognized. They are also sometimes known as gumboots or sea cradles or coat-of-mail shells or suck-rocks, or more formally as loricates, polyplacophorans, and occasionally as polyplacophores. Chitons have a shell composed of eight separate shell plates or valves. These plates overlap slightly at the front and back edges, and yet articulate well with one another. Because of this, the shell provides protection at the same time as permitting the chiton to flex upward when needed for locomotion over uneven surfaces, and even allows the animal to curl up into a ball when dislodged from rocks. The shell plates are encircled by a skirt known as a girdle. Habitat Chitons live worldwide, from cold waters through to the tropics. They live on hard surfaces, such as on or under rocks, or in rock crevices. Some species live quite high ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acanthopleura Echinata
''Acanthopleura echinata'' is a Southeast Pacific species of edible chiton, a marine polyplacophoran mollusc in the family Chitonidae, the typical chitons. Description ''Acanthopleura echinata'' is a very large chiton, with specimen confirmed at length of up to . In Chile, the largest individuals are in the north and the smallest in the south. The species is very dark reddish-brown. The plated shell, which often is covered in epibionts like algae, ''Scurria'' limpets and '' Mytilus'' mussels, has many spines. These spines are generally up to long in large individuals, but can be even longer if not broken, which however is unusual. The similar-sized '' Enoplochiton niger'' of the same region lacks the spines. Distribution, habitat and behavior The distribution of ''Chiton magnificus'' ranges along the Pacific coast of South America from Concepción Province (Punta Tumbes) in Chile to Talara in Peru. Although there are old claimed records of this species from the Galápagos Islan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subtidal
The neritic zone (or sublittoral zone) is the relatively shallow part of the ocean above the drop-off of the continental shelf, approximately in depth. From the point of view of marine biology it forms a relatively stable and well-illuminated environment for marine life, from plankton up to large fish and corals, while physical oceanography sees it as where the oceanic system interacts with the coast. Definition (marine biology), context, extra terminology In marine biology, the neritic zone, also called coastal waters, the coastal ocean or the sublittoral zone, refers to that zone of the ocean where sunlight reaches the ocean floor, that is, where the water is never so deep as to take it out of the photic zone. It extends from the low tide mark to the edge of the continental shelf, with a relatively shallow depth extending to about 200 meters (660 feet). Above the neritic zone lie the intertidal (or eulittoral) and supralittoral zones; below it the continental slope begi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Galápagos Islands
The Galápagos Islands (Spanish: , , ) are an archipelago of volcanic islands. They are distributed on each side of the equator in the Pacific Ocean, surrounding the centre of the Western Hemisphere, and are part of the Republic of Ecuador. Located west of continental Ecuador, the islands are known for their large number of endemic species that were studied by Charles Darwin during the second voyage of HMS ''Beagle''. His observations and collections contributed to the inception of Darwin's theory of evolution by means of natural selection. The Galápagos Islands and their surrounding waters form the Galápagos Province of Ecuador, the Galápagos National Park, and the Galápagos Marine Reserve. The principal language on the islands is Spanish. The islands have a population of slightly over 25,000. The first recorded visit to the islands happened by chance in 1535, when Fray Tomás de Berlanga, the Bishop of Panamá, was surprised to find this undiscovered land on a vo ...

Cape Horn
Cape Horn ( es, Cabo de Hornos, ) is the southernmost headland of the Tierra del Fuego archipelago of southern Chile, and is located on the small Hornos Island. Although not the most southerly point of South America (which are the Diego Ramírez Islands), Cape Horn marks the northern boundary of the Drake Passage and marks where the Atlantic and Pacific Oceans meet. Cape Horn was identified by mariners and first rounded in 1616 by the Dutchman Willem Schouten and Jacob Le Maire, who named it after the city of Hoorn in the Netherlands. For decades, Cape Horn was a major milestone on the clipper route, by which sailing ships carried trade around the world. The waters around Cape Horn are particularly hazardous, owing to strong winds, large waves, strong currents and icebergs. The need for boats and ships to round Cape Horn was greatly reduced by the opening of the Panama Canal in August 1914. Sailing around Cape Horn is still widely regarded as one of the major challenges in y ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
