Convict Tang
''Acanthurus triostegus'', also known as the convict tang, convict surgeonfish, or manini, is a small surgeonfish in family Acanthuridae of the order Perciformes. It is typically about long, but some individuals may reach 27 cm. These tangs are widespread. They are found in the Indo-Pacific except for seas around the Arabian Peninsula, in the Pacific at the Hawaiian Islands, and in the Eastern Pacific they are found in the lower Gulf of California and down to Panama, including the Revillagigedo Islands, Clipperton Island, Cocos Island, and Galápagos Islands The Galápagos Islands ( es, Islas Galápagos) are an archipelago of volcanic islands in the Eastern Pacific, located around the Equator west of the mainland of South America. They form the Galápagos Province of the Republic of Ecuador, with ... with some reports throughout the Mediterranean and Adriatic Sea most likely entering through the Suez Canal.

Carl Linnaeus
Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his ennoblement in 1761 as Carl von Linné Blunt (2004), p. 171. (), was a Swedish botanist, zoologist, taxonomist, and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was born in Råshult, the countryside of Småland, in southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he continued to coll ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cocos Island
Cocos Island ( es, Isla del Coco) is an island in the Pacific Ocean administered by Costa Rica, approximately southwest of the Costa Rican mainland. It constitutes the 11th of the 13 districts of Puntarenas Canton of the Province of Puntarenas. With an area of approximately , the island is more or less rectangular in shape. It is the southernmost point of geopolitical North America if non-continental islands are included. The entirety of Cocos Island has been designated a Costa Rican National Park since 1978, and has no permanent inhabitants other than Costa Rican park rangers. Surrounded by deep waters with counter-currents, Cocos Island is admired by scuba divers for its populations of hammerhead sharks, rays, dolphins and other large marine species. The wet climate and oceanic qualities give Cocos an ecological character that is not shared with either the Galápagos Archipelago or any of the other islands (for example, Malpelo, Gorgona or Coiba) in the eastern Pac ...

Fish Of Palau
Fish are aquatic, craniate, gill-bearing animals that lack limbs with digits. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups. Approximately 95% of living fish species are ray-finned fish, belonging to the class Actinopterygii, with around 99% of those being teleosts. The earliest organisms that can be classified as fish were soft-bodied chordates that first appeared during the Cambrian period. Although they lacked a true spine, they possessed notochords which allowed them to be more agile than their invertebrate counterparts. Fish would continue to evolve through the Paleozoic era, diversifying into a wide variety of forms. Many fish of the Paleozoic developed external armor that protected them from predators. The first fish with jaws appeared in the Silurian period, after which many (such as sharks) became formidable marine predators rather than just the prey of arthropods. Most fi ...

Acanthurus
''Acanthurus'' is a genus of fish in the family Acanthuridae found in the Atlantic, Indian and Pacific Ocean. They are found in tropical oceans, especially near coral reefs, with most species in the Indo-Pacific but a few are found in the Atlantic Ocean. As other members of the family, they have a pair of spines, one on either side of the base of the tail which are dangerously sharp. Species There are currently 41 recognized species in this genus: * ''Acanthurus achilles'' G. Shaw, 1803 (Achilles surgeonfish) * ''Acanthurus albimento'' K. E. Carpenter, J. T. Williams & M. D.

Acanthurus Polyzona
''Acanthurus polyzona'', commonly known as the black-barred surgeonfish or zebra tang, is a tropical fish found in coral reefs in the western Indian Ocean. It was first described in 1868 by the Dutch ichthyologist Pieter Bleeker, who gave it the name ''Rhombotides polyzona''; it was later transferred to the genus ''Acanthurus'', becoming ''Acanthurus polyzona''. Description ''Acanthurus polyzona'' is a laterally flattened fish, roughly the shape of an almond, and can grow to a length of about . The head is short with a pointed snout and a terminal mouth with thick lips. The eyes are large and the two pairs of nostrils are immediately in front of the eyes. The overall colour of this fish is a very pale yellow, rather more olive-grey dorsally and more silvery-white ventrally. Superimposed on this pale background are nine broad black bands, narrowing slightly towards the belly; the first band passes through the eye, the second extends from the front of the dorsal fin to the base of ...

Galápagos Islands
The Galápagos Islands ( es, Islas Galápagos) are an archipelago of volcanic islands in the Eastern Pacific, located around the Equator west of the mainland of South America. They form the Galápagos Province of the Republic of Ecuador, with a population of slightly over 33,000 (2020). The province is divided into the Cantons of Ecuador, cantons of San Cristóbal Island, San Cristóbal, Santa Cruz Island (Galápagos), Santa Cruz, and Isabela Island (Galápagos), Isabela, the three most populated islands in the chain. The Galápagos are famous for their large number of Endemism, endemic species, which were studied by Charles Darwin in the 1830s and inception of Darwin's theory, inspired his theory of evolution by means of natural selection. All of these islands are protected as part of Ecuador's Galápagos National Park and Galápagos Marine Reserve, Marine Reserve. Thus far, there is no firm evidence that Polynesian expansion, Polynesians or the indigenous peoples of South Am ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clipperton Island
Clipperton Island ( or ; ) is an uninhabited, coral atoll in the eastern Pacific Ocean. It is from Paris, France, from Papeete, Tahiti, and from Mexico. It is an overseas state private property of France under direct authority of the Minister of the Overseas. In the past, Clipperton Island was the subject of a sovereignty dispute in particular between France and Mexico, which was finally settled through arbitration in 1931; the ''Clipperton Island Case'' remains widely studied in international law textbooks. Geography The atoll is south-west of Mexico, west of Nicaragua, west of Costa Rica and north-west of the Galápagos Islands, Ecuador, at . Clipperton is about south-east of Socorro Island in the Revillagigedo Archipelago, which is the nearest land, while the nearest French-owned island is Hiva Oa. Some consider it to be one of the eastern-most points of Oceania, rather than an outlying island of the Americas. It is low-lying and largely barren, with some sc ...

10th Edition Of Systema Naturae
The 10th edition of ''Systema Naturae'' is a book written by Swedish naturalist Carl Linnaeus and published in two volumes in 1758 and 1759, which marks the starting point of zoological nomenclature. In it, Linnaeus introduced binomial nomenclature for animals, something he had already done for plants in his 1753 publication of ''Species Plantarum''. Starting point Before 1758, most biological catalogues had used polynomial names for the taxa included, including earlier editions of ''Systema Naturae''. The first work to consistently apply binomial nomenclature across the animal kingdom was the 10th edition of ''Systema Naturae''. The International Commission on Zoological Nomenclature therefore chose 1 January 1758 as the "starting point" for zoological nomenclature, and asserted that the 10th edition of ''Systema Naturae'' was to be treated as if published on that date. Names published before that date are unavailable, even if they would otherwise satisfy the rules. The onl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Revillagigedo Islands
The Revillagigedo Islands ( es, Islas Revillagigedo, ) or Revillagigedo Archipelago are a group of four volcanic islands in the Pacific Ocean, known for their unique ecosystem. They lie approximately from Socorro Island south and southwest of Cabo San Lucas, the southern tip of the Baja California Peninsula, and west of Manzanillo. Historically linked to the Mexican state of Colima, to which they were granted in 1861 to establish a penal colony, the islands are under Mexican federal property and jurisdiction. In July 2016, the Revillagigedo Archipelago was inscribed as a UNESCO World Heritage Site, and in November 2017 they were declared to be a marine reserve and a national park of Mexico. Some of the volcanoes are active, with the last eruption of Volcán Bárcena in 1953, and Socorro in 1993. Travelling to the islands from their nearest land point takes approximately 26 to 30 hours, as they are typically reached by sea; a small military airstrip exists on Socorro. Geogr ...
