Mochokidae
The Mochokidae are a family of catfishes ( order Siluriformes) that are known as the squeakers and upside-down catfish (although not all species swim upside-down). There are nine genera and about 200 species of mochokids. All the mochokids are freshwater species originating from Africa. They have three pairs of barbels, with the nasal barbels absent; sometimes, the mandibular barbels may be branched. The lips are modified into a suckermouth in '' Atopochilus'', ''Chiloglanis'', and '' Euchilichthys''. The adipose fin is usually very long. The dorsal and pectoral fins have spines that are usually strong and with a locking mechanism. They range in size up to SL. This group contains many popular species among aquarists, such as ''Synodontis nigriventris'', '' Synodontis angelicus'', and ''Synodontis multipunctatus ''Synodontis multipunctatus'', also known as the cuckoo catfish, cuckoo squeaker, or multipunk, is a small catfish from Lake Tanganyika, one of the lakes in the Great R ...

IUCN Red List Of Threatened Species
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biological species. It uses a set of precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. With its strong scientific base, the IUCN Red List is recognized as the most authoritative guide to the status of biological diversity. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit. The aim of the International Union for Conservation of Nature, IUCN Red List is to convey the urgency of conservation issues to the public and policy makers, as well as help the international community to reduce species extinction.

Nyanga River
The Nyanga River, 600 km, is a river that runs through southern Gabon and northern Republic of the Congo. It is the second most important river in Gabon after the Ogooue. It is well known for the numerous rapids that break up its otherwise smooth course. Course It rises on the border between the two countries, near the juncture of N'Gounié and Ogooué-Lolo provinces of Gabon, runs south along the border and then southwest through the Niari province of Congo, then enters the Nyanga province of Gabon and makes a sharp bend to the northwest. It passes through Nyanga's capital Tchibanga (the largest city on the river), then gradually bends around to the southwest again, running through a series of rapids before coming out onto a coastal plain and emptying into the Atlantic Ocean.

Catfish Of Africa
Catfish (or catfishes; order Siluriformes or Nematognathi) are a diverse group of ray-finned fish. Named for their prominent barbels, which resemble a cat's whiskers, catfish range in size and behavior from the three largest species alive, the Mekong giant catfish from Southeast Asia, the wels catfish of Eurasia, and the piraíba of South America, to detritivores (species that eat dead material on the bottom), and even to a tiny parasitic species commonly called the candiru, ''Vandellia cirrhosa''. Neither the armour-plated types nor the naked types have scales. Despite their name, not all catfish have prominent barbels or "whiskers". Members of the Siluriformes order are defined by features of the skull and swimbladder. Catfish are of considerable commercial importance; many of the larger species are farmed or fished for food. Many of the smaller species, particularly the genus ''Corydoras'', are important in the aquarium hobby. Many catfish are nocturnal, [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fish Described In 2008
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 f ...

Dominique Adriaens
"Dominique" is a 1963 French language popular song, written and performed by the Belgian female singer Jeannine Deckers, better known as Sœur Sourire ("Sister Smile" in French) or The Singing Nun. The song is about Saint Dominic, a Spanish-born priest and founder of the Dominican Order, of which she was a member (as Sister Luc-Gabrielle). The English-version lyrics of the song were written by Noël Regney. In addition to French and English, Deckers recorded versions in Dutch, German, Hebrew, Japanese, Korean, and Portuguese. It was a top selling record in 11 countries in late 1963 and early 1964. Commercial performance "Dominique" reached the Top 10 in 11 countries in late 1963 and early 1964, topping the chart in the United States, Canada, Australia and New Zealand. It reached the Top 5 in Norway, Denmark, Ireland and South Africa, with the song making it into the lower reaches of the Top 10 in the Netherlands, West Germany, and the United Kingdom.

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 ...

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. Total length meas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ngounié River
The Ngounié River (also Ngunyé) is a river flowing through southwest-central Gabon. It is the last and second most important tributary of the Ogooué River, the first being the Ivindo River. It initially flows down from the Chaillu Mountains, along the border with Congo, and then turns northwest, flowing through the towns of Fougamou, Sindara and Mouila before flowing into the Ogooué. Etymology The river name, Ngounié, is a French rewording of "Ngugni", which was originally used by Vili language speakers in the Samba Falls/ Imperatrice Falls area in the mid-1800s to call the northern border of their district, "Nsina-Ngugni". When Robert Bruce Napoleon Walker and Paul Du Chaillu arrived in the area, they wrote down "Ngouyai" or "Ngunyé". The Gisir and Punu language speakers of Gabon know the river as "Durembu-du-Manga", while the Apindji, Eviya and Tsogo speakers know it as Otembo-a-Manga. The Kele speakers know it as "Melembye-a-Manga". The first part of these names mean ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ivindo River
The Ivindo River is the most important tributary of the Ogooué River, which flows in Gabon. Course The Ivindo River flows from northeast Gabon to the southwest, eventually emptying into the Ogooué River. It flows through some of the wildest and most attractive rainforest in Africa. The upper stretch of the river is fairly gentle, draining the gentle plateau of eastern Gabon. Below the town of Makokou, the only significant town on the river, it drops off the plateau in a series of spectacular waterfalls and gorges.
