Max Poll
Max Fernand Leon Poll (21 July 1908 in Ruisbroek – 13 March 1991 in Uccle) was a Belgian ichthyologist who specialised in the Cichlidae. In the years 1946 and 1947 he organised an expedition to Lake Tanganyika. He has described several species of Pseudocrenilabrinae, such as ''Lamprologus signatus'', ''Steatocranus casuarius'', ''Neolamprologus brichardi'', and '' Neolamprologus pulcher''. He was a member of The Royal Academies for Science and the Arts of Belgium, professor at Université Libre de Bruxelles, and conservator at Musée Royal du Congo Belge in Tervuren. He was an honorary member of the American Society of Ichthyologists and Herpetologists. Taxon named in his honor Named after him are species and taxa such as: *The African Lanternshark '' Etmopterus polli'' Bigelow, Schroeder & S.

Ray-finned Fish
Actinopterygii (; ), members of which are known as ray-finned fishes, is a class of bony fish. They comprise over 50% of living vertebrate species. The ray-finned fishes are so called because their fins are webs of skin supported by bony or horny spines (rays), as opposed to the fleshy, lobed fins that characterize the class Sarcopterygii (lobe-finned fish). These actinopterygian fin rays attach directly to the proximal or basal skeletal elements, the radials, which represent the link or connection between these fins and the internal skeleton (e.g., pelvic and pectoral girdles). By species count, actinopterygians dominate the vertebrates, and they constitute nearly 99% of the over 30,000 species of fish. They are ubiquitous throughout freshwater and marine environments from the deep sea to the highest mountain streams. Extant species can range in size from '' Paedocypris'', at , to the massive ocean sunfish, at , and the long-bodied oarfish, at . The vast majority of Actino ...

Labeobarbus
''Labeobarbus'' is a mid-sized ray-finned fish genus in the family Cyprinidae. Its species are widely distributed throughout eastern Africa and especially southern Africa, but also in Lake Tana in Ethiopia. A common name, in particular for the southern species, is yellowfish. The scientific name refers to the fact that these large barbs remind of the fairly closely related "carps" in the genus '' Labeo'' in size and shape. As far as can be told, all ''Labeobarbus'' species are hexaploid.de Graaf ''et al.'' (2007), IUCN (2009) Systematics Like many other "barbs", it was long included in '' Barbus''. It appears to be a fairly close relative of the typical barbels and relatives – the genus ''Barbus'' proper –, but closer still to the large Near Eastern species nowadays separated in '' Carasobarbus''. ''Barbus'' has been split to account for the improved phylogenetic knowledge which indicated it was highly paraphyletic in its wide circumscription –, it ...

Lufira River
The Lufira River is a tributary of the Lualaba River in the Democratic Republic of the Congo (DRC). The Lufira rises in the Shaba plateau south of Likasi. The river was dammed in 1926 at Mwadingusha near Likasi to form Lake Tshangalele, a reservoir for a hydroelectric generator supplying power for copper smelting. It flows northwards through the Bia Mountains for about , joining the Lualaba in Lake Kisale Lake Kisale is a lake in the Democratic Republic of the Congo (DRC), in Bukama Territory, Haut-Lomami District. At about in area, it is the second largest of the lakes in the Upemba Depression (Kamolondo Depression), an extensive marshy area part ....

Democratic Republic Of The Congo
The Democratic Republic of the Congo (french: République démocratique du Congo (RDC), colloquially "La RDC" ), informally Congo-Kinshasa, DR Congo, the DRC, the DROC, or the Congo, and formerly and also colloquially Zaire, is a country in Central Africa. It is bordered to the northwest by the Republic of the Congo, to the north by the Central African Republic, to the northeast by South Sudan, to the east by Uganda, Rwanda, and Burundi, and by Tanzania (across Lake Tanganyika), to the south and southeast by Zambia, to the southwest by Angola, and to the west by the South Atlantic Ocean and the Cabinda exclave of Angola. By area, it is the second-largest country in Africa and the 11th-largest in the world. With a population of around 108 million, the Democratic Republic of the Congo is the most populous officially Francophone country in the world. The national capital and largest city is Kinshasa, which is also the nation's economic center. Centered on the Congo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fish Described In 1973
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 ...
