Synodontis Congicus
''Synodontis congicus'' is a species of upside-down catfish native to the Democratic Republic of the Congo and the Republic of the Congo where it occurs in the upper and middle Congo Basin. It was first described by Belgian ichthyologist Max Poll in 1971. The first specimen was found near the town of Gangala-na-Bodio, Democratic Republic of the Congo, in the Dungu River. The meaning of the specific name Specific name may refer to: * in Database management systems, a system-assigned name that is unique within a particular database In taxonomy, either of these two meanings, each with its own set of rules: * Specific name (botany), the two-part (bino ... ''"congicus"'' is "From the Congo". Description The fish is light grey to silver in color, with one to four spots along the midlateral line of the body. Like other members of the genus, this fish has a humeral process, which is a bony spike that is attached to a hardened head cap on the fish and can be seen extending beyond ...

Max Poll
Max Fernand Leon Poll (21 July 1908 in Ruisbroek, Flemish Brabant, Ruisbroek – 13 March 1991 in Uccle) was a Belgians, Belgian ichthyologist who specialised in the Cichlidae. In the years 1946 and 1947 he organised an exploration, expedition to Lake Tanganyika. He has described several species of Pseudocrenilabrinae, such as ''Lamprologus signatus'', ''Steatocranus casuarius'', ''Neolamprologus brichardi'', and ''Neolamprologus pulcher''.

Lake Mweru
Lake Mweru (also spelled ''Mwelu'', ''Mwero'') is a freshwater lake on the longest arm of Africa's second-longest river, the Congo. Located on the border between Zambia and Democratic Republic of the Congo, it makes up of the total length of the Congo, lying between its Luapula River (upstream) and Luvua River (downstream) segments.Google Earth accessed 29 March 2007. When in flood Lake Bangweulu and its swamps may temporarily have a larger area, but not a larger volume. Mweru means 'lake' in a number of Bantu languages, so it is often referred to as just 'Mweru'.The ''Northern Rhodesia Journal'' online at NZRAM.org: J B W Anderson: "Kilwa Island and the Luapula." Vol II, No. 3 pp87–88 (1954) Physical geography Mweru is mainly fed by the Luapula River, which comes in through swamps from the south, and the Kalungwishi River from the east. At its north end the lake is drained by the Luvua River, which flows in a northwesterly direction to join the Lualaba River and thence to th ...

Fish Of The Republic Of The Congo
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 ...

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] |
Synodontis
''Synodontis'' is the largest genus of mochokid catfishes. It is the biggest genus within the 10 genera and 190 different species in the family Mochokidae. ''Synodontis'' has over 131 different species within the genus. ''Synodontis'' are also known as squeakers, due to their ability to make stridulatory sounds through their pectoral fin spines when handled or disturbed. ''Synodontis'' make a sound that sounds like squeaking by rubbing their spines together. They do this when they have been frightened or when they become angry. ''Synodontis'' may also squeak when they are taken out of the water. These catfish are small- to medium-sized fish with many species exhibiting attractive spotted markings. Some species are also known for naturally swimming belly-up, earning the name upside-down catfish. Some of these species are '' Synodontis contractus'' and '' Synodontis nigriventris''. While some of these species are known to swim upside down, another species, '' Synodontis multipunct ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IUCN
The International Union for Conservation of Nature (IUCN; officially International Union for Conservation of Nature and Natural Resources) is an international organization working in the field of nature conservation and sustainable use of natural resources. It is involved in data gathering and analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through building partnerships. The organization is best known to the wider ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The 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 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. According to IUCN the formally stated goals of the Red List are to provide sc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Luapula River
The Luapula River is a section of Africa's second-longest river, the Congo. It is a transnational river forming for nearly all its length part of the border between Zambia and the DR Congo. It joins Lake Bangweulu (wholly in Zambia) to Lake Mweru (shared between the two countries) and gives its name to the Luapula Province of Zambia.Terracarta/International Travel Maps, Vancouver Canada: "Zambia, 2nd edition", 2000 Source and upper Luapula The Luapula drains Lake Bangweulu and its swamps into which flows the Chambeshi River, the source of the Congo. There is no single clear channel connecting the two rivers and the lake, but a mass of shifting channels, lagoons and swamps, as the explorer David Livingstone found to his cost. (He died exploring the area, and one of his last acts was to question Chief Chitambo about the course of the Luapula.)Blaikie, William Garden (1880): ''The Personal Life Of David Livingstone''Project Gutenberg Ebook #13262 release date: August 23, 2004.D ...

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 ...

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] |
Specific Name (zoology)
In zoological nomenclature, the specific name (also specific epithet or species epithet) is the second part (the second name) within the scientific name of a species (a binomen). The first part of the name of a species is the name of the genus or the generic name. The rules and regulations governing the giving of a new species name are explained in the article species description. For example, the scientific name for humans is ''Homo sapiens'', which is the species name, consisting of two names: ''Homo'' is the " generic name" (the name of the genus) and ''sapiens'' is the "specific name". Historically, ''specific name'' referred to the combination of what are now called the generic and specific names. Carl Linnaeus, who formalized binomial nomenclature, made explicit distinctions between specific, generic, and trivial names. The generic name was that of the genus, the first in the binomial, the trivial name was the second name in the binomial, and the specific the proper term for ...
