Georg Johann Pfeffer
Georg Johann Pfeffer (1854–1931) was a German zoologist, primarily a malacologist, a scientist who studies mollusks. Pfeffer was born in Berlin. In 1887 he became curator of the , which was established in 1843 and destroyed during World War II. Pfeffer's published writings were mainly about cephalopods. The World Register of Marine Species database lists 133 marine taxa named by Pfeffer When Pfeffer's name is listed as an authority for a taxon such as the land snail genus ''Lamellaxis'' Strebel & Pfeffer, 1882, his name is ''not'' simply an orthographic error for the more commonly encountered molluscan authority Pfeiffer, i.e. Ludwig Karl Georg Pfeiffer, who lived 50 years earlier, from 1805 to 1877. Georg Johann Pfeffer also studied amphibians and reptiles, naming several new species. Two species of reptiles are named in his honor, ''Calamaria pfefferi Pfeffer's reed snake, ''Calamaria pfefferi'', is a species of dwarf snake in the family Colubridae. The spe ...

Schilbid Catfish
Schilbeidae is a family of catfishes native to Africa and Asia. These fish tend to swim in open water. Schilbid catfishes usually have dorsal fins with a short base and a spine, but ''Parailia'' lack a dorsal fin altogether. Most species also possess an adipose fin. The base of the anal fin is very long. There are usually four pairs of barbels. Several species lack anal fin Fins are distinctive anatomical features composed of bony spines or rays protruding from the body of a fish. They are covered with skin and joined together either in a webbed fashion, as seen in most bony fish, or similar to a flipper, as se ...s. The family name is sometimes spelled Schilbidae in scientific literature. References Fish of Africa Fish of Asia Catfish families Taxa named by Pieter Bleeker {{catfish-stub ...

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] |
Tanzania
Tanzania (; ), officially the United Republic of Tanzania ( sw, Jamhuri ya Muungano wa Tanzania), is a country in East Africa within the African Great Lakes region. It borders Uganda to the north; Kenya to the northeast; Comoro Islands and the Indian Ocean to the east; Mozambique and Malawi to the south; Zambia to the southwest; and Rwanda, Burundi, and the Democratic Republic of the Congo to the west. Mount Kilimanjaro, Africa's highest mountain, is in northeastern Tanzania. According to the United Nations, Tanzania has a population of million, making it the most populous country located entirely south of the equator. Many important hominid fossils have been found in Tanzania, such as 6-million-year-old Pliocene hominid fossils. The genus Australopithecus ranged across Africa between 4 and 2 million years ago, and the oldest remains of the genus ''Homo'' are found near Lake Olduvai. Following the rise of '' Homo erectus'' 1.8 million years ago, humanity spread ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ruaha River
The Great Ruaha River is a river in south-central Tanzania that flows through the Usangu wetlands and the Ruaha National Park east into the Rufiji River. It traverses and marks the borders between Iringa Region, Dodoma Region and Morogoro Region. The Great Ruaha river has a basin catchment area of . The population of the basin is mainly sustained by irrigation and water-related livelihoods such as fishing and livestock keeping. Size Great Ruaha is about long, its tributary basin has a catchment area of and the mean annual discharge is per second. The Great Ruaha River supplies 22 percent of the total flow of the Rufiji catchment system. Thirty-eight species of fish have been identified in the Great Ruaha River. The river's headwaters are in the Kipengere Range In west Njombe Region. From there the Great Ruaha River descends to the Usangu plains, an important region for irrigated agriculture and livestock in Tanzania. The river eventually reaches the Mtera Dam and th ...

Kingani River
HMS ''Fifi'' was an armed screw steamer, captured from the Germans by Royal Navy units during the Battle for Lake Tanganyika, and used to support Anglo-Belgian operations on the lake and its surrounding areas. She had previously been operated by the Germans under the name ''Kingani'' named after the river Kingani. After a short career supporting German troop movements in central Africa, she was unexpectedly challenged by two motor boats, named HMS ''Mimi'' and HMS ''Toutou'', which had been transported from Britain to the lake by an expedition led by Lieutenant-Commander Geoffrey Spicer-Simson. The faster and more nimble motor boats were able to chase down ''Kingani'', which was unable to bring her larger weapon to bear on the small vessels without turning to face them. After being hit several times and crippled, and with her commanding officer and several men dead, she surrendered and was brought back to the British base. Brought into British service as ''Fifi'', she becam ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kilombero River
The Ulanga River, also known as the Kilombero River, rises in the highlands of the southwest of Morogoro Region, Tanzania, on the eastern slope of the East African Rift. The river flows northeast along the northeastern border of the Lindi Region before it flows into the Rufiji River. The Rufiji eventually flows into the Indian Ocean on the southern coast of the Pwani Region. Geology The Ulanga Valley is an intact natural wetland ecosystem comprising myriad rivers, which make up the largest seasonally freshwater lowland floodplain in East Africa. The Ulanga River supplies two thirds of the Rufiji waters. The Ulanga River is formed by the convergence of major rivers coming from the south, that flow north from the mountain ranges of the Njombe and Iringa regions on the eastern slope of the East African Rift and south from the Udzungwa Mountains and Mahenge Mountains. From south the Ruhudji River winds eastward, losing height quite rapidly, to the head of the great floodplain of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |

Freshwater Fish Of Tanzania
Fresh water or freshwater is any naturally occurring liquid or frozen water containing low concentrations of dissolved salts and other total dissolved solids. Although the term specifically excludes seawater and brackish water, it does include non- salty mineral-rich waters such as chalybeate springs. Fresh water may encompass frozen and meltwater in ice sheets, ice caps, glaciers, snowfields and icebergs, natural precipitations such as rainfall, snowfall, hail/ sleet and graupel, and surface runoffs that form inland bodies of water such as wetlands, ponds, lakes, rivers, streams, as well as groundwater contained in aquifers, subterranean rivers and lakes. Fresh water is the water resource that is of the most and immediate use to humans. Water is critical to the survival of all living organisms. Many organisms can thrive on salt water, but the great majority of higher plants and most insects, amphibians, reptiles, mammals and birds need fresh water to survive. ...

Fish Described In 1896
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. Mos ...
