Fernando Cervigón
Fernando Cervigón Marcos (born Valencia on 15 May 1930, died Caracas 17 May 2017) was a Spanish ichthyologist and marine biologist, who lived most of his life in Venezuela. He discovered and described numerous species of fish including the Caribbean roughshark and is author of numerous works on fish and Venezuela's ocean environment including ''Los Peces Marinos de Venezuela''. He was the president of the Museo del Mar on Margarita Island, Nueva Esparta, Venezuela. Early life Fernando Cervigón Marcos was born in Valencia, Spain, on 15 May 1930. His secondary education was undertaken at the ''Colegio de Hermans Maristas'' between 1940 and 1948. In 1948 he matriculated at the University of Barcelona and he graduated for there with a Bachelor's degree in Natural Sciences. He completed a post-graduate course in 1958 and obtained a doctorate in Biological Sciences in 1964. His thesis for his doctoe was entitled ''Los Peces Marinos de Venezuela'' ("The marine fishes of Venezuela" ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chaenopsidae
The blennioid family Chaenopsidae includes the pike-blennies, tube-blennies, and flagblennies, all percomorph marine fish in the order Blenniiformes. The family is strictly tropical, ranging from North to South America. Members are also present in waters off Japan, Taiwan and Korea. Fourteen genera and 90 species are represented, the largest being the sarcastic fringehead, ''Neoclinus blanchardi'', at in length; most are much smaller, and the group includes perhaps the smallest of all vertebrates, ''Acanthemblemaria paula'', measuring just long as an adult. With highly compressed bodies, some may be so elongated as to appear eel-like; chaenopsids are scaleless and lack lateral lines. Their heads are rough and may be armed with spines. There may be 17 to 28 spines in the dorsal fin, with two in the anal fin. The habit of taking up home in abandoned worm tubes has earned some species in this family the name "tube-blenny". Many will also inhabit empty clam shells, which also ser ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cubagua Island
Cubagua Island or Isla de Cubagua () is the smallest and least populated of the three islands constituting the Venezuelan state of Nueva Esparta, after Margarita Island and Coche Island. It is located north of the Araya Peninsula, the closest mainland area. Geography Topography The island is in size, an elliptical shape with the longer axis east-west. Its area is . The coast consists of some beaches as well as cliffs from high in the south and from high in the north. The highest elevation of the flat-topped island reaches . Climate It is dry and lacks surface water bodies (the only freshwater is found in small underground reservoirs). Annual precipitation is , which is the value of a dry desert. Temperatures are close to year-round with little fluctuation. Vegetation The desert-like ( xerophytic) vegetation of the essentially barren island includes a number of cactus species such as Cardón de Dato ('' Ritterocereus griseus''), Buche, Melón de Cerro, Sabana o Monte (''Me ...

Venezuela
Venezuela (; ), officially the Bolivarian Republic of Venezuela ( es, link=no, República Bolivariana de Venezuela), is a country on the northern coast of South America, consisting of a continental landmass and many islands and islets in the Caribbean Sea. It has a territorial extension of , and its population was estimated at 29 million in 2022. The capital and largest urban agglomeration is the city of Caracas. The continental territory is bordered on the north by the Caribbean Sea and the Atlantic Ocean, on the west by Colombia, Brazil on the south, Trinidad and Tobago to the north-east and on the east by Guyana. The Venezuelan government maintains a claim against Guyana to Guayana Esequiba. Venezuela is a federal presidential republic consisting of 23 states, the Capital District and federal dependencies covering Venezuela's offshore islands. Venezuela is among the most urbanized countries in Latin America; the vast majority of Venezuelans live in the cities of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atlantic
The Atlantic Ocean is the second-largest of the world's five oceans, with an area of about . It covers approximately 20% of Earth's surface and about 29% of its water surface area. It is known to separate the "Old World" of Africa, Europe and Asia from the "New World" of the Americas in the European perception of the World. The Atlantic Ocean occupies an elongated, S-shaped basin extending longitudinally between Europe and Africa to the east, and North and South America to the west. As one component of the interconnected World Ocean, it is connected in the north to the Arctic Ocean, to the Pacific Ocean in the southwest, the Indian Ocean in the southeast, and the Southern Ocean in the south (other definitions describe the Atlantic as extending southward to Antarctica). The Atlantic Ocean is divided in two parts, by the Equatorial Counter Current, with the North(ern) Atlantic Ocean and the South(ern) Atlantic Ocean split at about 8°N.

Fish Measurement
Fish measurement is the measuring of individual fish and various parts of their anatomies. These data are used in many areas of ichthyology, including taxonomy and fisheries biology. Overall length * Standard length (SL) is the length of a fish measured from the tip of the snout to the posterior end of the last vertebra or to the posterior end of the midlateral portion of the hypural plate. Simply put, this measurement excludes the length of the caudal (tail) fin. * Total length (TL) is the length of a fish measured from the tip of the snout to the tip of the longer lobe of the caudal fin, usually measured with the lobes compressed along the midline. It is a straight-line measure, not measured over the curve of the body. Standard length measurements are used with Teleostei (most bony fish), while total length measurements are used with Myxini ( hagfish), Petromyzontiformes ( lampreys), and (usually) Elasmobranchii (shark Sharks are a group of elasmobranch fish chara ...

Fish Described In 1970
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 ...

Taxa Named By John S
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the int ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
