Chiton
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 hi ... [...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] |

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] |
Marine (ocean)
The ocean (also the sea or the world ocean) is the body of salt water that covers approximately 70.8% of the surface of Earth and contains 97% of Earth's water. An ocean can also refer to any of the large bodies of water into which the world ocean is conventionally divided."Ocean." ''Merriam-Webster.com Dictionary'', Merriam-Webster, |
Mollusc
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.

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Coquimbo
Coquimbo is a port city, commune and capital of the Elqui Province, located on the Pan-American Highway, in the Coquimbo Region of Chile. Coquimbo is situated in a valley south of La Serena, with which it forms Greater La Serena with more than 400,000 inhabitants. The commune spans an area around the harbor of . The average temperature in the city lies around , and precipitation is low. History The area was originally occupied by indigenous people, who used it as a settlement and for fishing purposes. The natural harbour in Coquimbo was taken over by Pedro de Valdivia from Spain in 1550. The gold and copper industry in the region led to the city's importance as a port around 1840 and many Europeans especially from England settled in Coquimbo. In 1879 it was recognised as a town. The city was on the main path of totality of the Solar eclipse of July 2, 2019. Demographics According to the 2002 census of the National Statistics Institute, Coquimbo had 163,036 inhabitants (79,428 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Talara
Talara is a city in the Talara Province of the Piura Region, in northwestern Peru. It is a port city on the Pacific Ocean with a population of 91,444 as of 2017. Its climate is hot and dry. Due to its oil reserves, and ability to produce aviation fuel, Talara hosted a United States air base during World War II. It was also one of two refueling stations for the Pacific Fleet. There were naval guns on the hills, and submarine nets in the harbor. The Ajax, Achilles and Exeter, three British destroyers, were refuelled there on their way around the Horn to catch the Graf Spee in Rio de la Plata. Talara is also home to a large fishing fleet. The city is served by the Cap. FAP Víctor Montes Arias Airport. Talara is the westernmost city in all of mainland South America. (A small outlying town, Seccion Dieciocho, is situated slightly further west, and just beyond there, the land itself reaches its westernmost extent at Punta Pariñas.)

Intertidal Zone
The intertidal zone, also known as the foreshore, is the area above water level at low tide and underwater at high tide (in other words, the area within the tidal range). This area can include several types of habitats with various species of life, such as seastars, sea urchins, and many species of coral with regional differences in biodiversity. Sometimes it is referred to as the ''littoral zone'' or '' seashore'', although those can be defined as a wider region. The well-known area also includes steep rocky cliffs, sandy beaches, bogs or wetlands (e.g., vast mudflats). The area can be a narrow strip, as in Pacific islands that have only a narrow tidal range, or can include many meters of shoreline where shallow beach slopes interact with high tidal excursion. The peritidal zone is similar but somewhat wider, extending from above the highest tide level to below the lowest. Organisms in the intertidal zone are adapted to an environment of harsh extremes, living in water pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
