Jean Cadenat
Jean Cadenat (born Marmande, Lot-et-Garonne 16 April 1908, died Marmande 28 June 1992) was a French ichthyologist. In 1930, he joined the Agricultural Zoology station at La Grand Ferrade as an assistant preparator and the following year he completed his BSc (''license'') at the University of Bordeaux. From January 1932 to December 1941 he was at La Rochelle as an assistant in the Laboratory of G. Belloc at the Scientific and Technical Office of Fisheries then headed by Edouard Le Danois. During this period, he participated in many research expeditions, firstly aboard trawlers to the coasts of Ireland, France, Spain, Morocco and Mauritania, as well as participating in the fifth scientific cruise of the ''President Theodore Tissier'' in 1936 which travelled from the Canary Islands to the coast of Sierra Leone. In 1934, he began his military service in the French Navy, serving aboard Fisheries Patrols. In 1939, he was mobilised back to active service in La Rochelle. When he was demobil ...

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] |
Labrisomid
Labrisomids are small blennioids (blennies), percomorph marine fish belonging to the family Labrisomidae. Found mostly in the tropical Atlantic and Pacific Ocean, the family contains about 110 species in 15 genera. Stockier than the average blenny, labrisomids are elongated nonetheless; their dorsal fin spines outnumber soft rays (which may be absent altogether), and their pelvic fins are long and slender. Like many other blennies, labrisomids have whisker-like structures called cirri on their heads and napes. Scales may be cycloid or absent in labrisomids; many species are brightly coloured. The hairy blenny (''Labrisomus nuchipinnis'') is the largest species at 23 cm in length; most are far smaller. Generally staying within shallow coastal regions to depths around 10 m, labrisomids are benthic fish spending most of their time on or near the bottom. Both sandy and rocky substrates are frequented, sometimes at reefs or amongst beds of seagrass. Labrisomids are shy fish a ...

Endemism
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Senegal

Senegal is bordered by Mauritania to the north, Mali to the east, Guinea to the southeast and Guinea-Bissau to the southwest. Senegal nearly surrounds the Gambia, a country occupying a narrow sliver of land along the banks of the Gambia River, which separates Senegal's southern region of Casamance from the rest of the country. Senegal also shares a maritime border with Cape Verde. Senegal's economic and political capital is Dakar. Senegal is notably the westernmost country in the mainland of the Old World, or Afro-Eurasia.

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 (sharks and rays), as well as some other fishes.

Fish Of West Africa
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 fis ...
