Guinea Highlands
The Guinea Highlands is a densely forested mountainous plateau extending from central Guinea through northern Sierra Leone and Liberia to western Ivory Coast. The highlands include a number of mountains, ranges and plateaus, including the Fouta Djallon highlands in central Guinea, the Loma Mountains in Sierra Leone, the Simandou and Kourandou massifs in southeastern Guinea, the Nimba Range at the border of Guinea, Liberia, and Ivory Coast, and the Monts du Toura in western Ivory Coast. Geography In Guinea they are known as ''Dorsale Guinéenne''. The highest peak in the region is Mount Bintumani in Sierra Leone, at 1,945 metres (6,381 ft). Other peaks include Sankan Biriwa () in Sierra Leone and Mount Richard-Molard (Mount Nimba) () on the border of Guinea and Ivory Coast. The highlands mostly lie between above sea level. The Guinea Highlands are the source of many of West Africa's rivers, including the Niger River, West Africa's longest river, the Senegal and Gamb ...

Buchanan, Liberia
Buchanan ( bsq, Gbezohn), also previously known as Grand Bassa on some maps, is the third largest city in Liberia, lying on Waterhouse Bay, part of the Atlantic Ocean. As of the 2008 census, Buchanan had a population of 34,270. Of this, 16,984 were male and 17,286 female. Named for Thomas Buchanan, cousin of U.S. president James Buchanan, and second governor of Liberia, it is also the capital of Grand Bassa County and lies southeast of Monrovia, near the mouth of the Saint John River. The town was popular with refugees during the Liberian Civil War as it largely escaped the fighting. Fishing is an important industry in the town. The town also has isolated beaches and lagoons. History In December 1832, the Port Cresson colony was founded in what is now Buchanan, by black Quakers of the New York and Pennsylvania Colonization Societies. It was established as a settlement for black emigrants from the United States. The emigrants named the settlement in honor of Elliott Cresson ...

Tilapia
Tilapia ( ) is the common name for nearly a hundred species of cichlid fish from the coelotilapine, coptodonine, heterotilapine, oreochromine, pelmatolapiine, and tilapiine tribes (formerly all were "Tilapiini"), with the economically most important species placed in the Coptodonini and Oreochromini. Tilapia are mainly freshwater fish inhabiting shallow streams, ponds, rivers, and lakes, and less commonly found living in brackish water. Historically, they have been of major importance in artisanal fishing in Africa, and they are of increasing importance in aquaculture and aquaponics. Tilapia can become a problematic invasive species in new warm-water habitats such as Australia, whether deliberately or accidentally introduced, but generally not in temperate climates due to their inability to survive in cold water. Tilapia has been the fourth-most consumed fish in the United States since 2002. The popularity of tilapia came about due to its low price, easy preparation, and ...

Nile Perch
The Nile perch (''Lates niloticus''), also known as the African snook, Goliath perch, African barramundi , Goliath barramundi, Giant lates or the Victoria perch, is a species of freshwater fish in family Latidae of order Perciformes. It is widespread throughout much of the Afrotropical realm, being native to the Congo, Nile, Senegal, Niger and Lake Chad, Volta, Lake Turkana, and other river basins. It also occurs in the brackish waters of Lake Maryut in Egypt. The Nile perch is a fish of substantial economic and food-security importance in East Africa. Originally described as ''Labrus niloticus,'' among the marine wrasses, the species has also been referred to as ''Centropomus niloticus''. Common names include African snook, Victoria perch (a misleading trade name, as the species is not native to Lake Victoria, though they have been introduced there), and many local names in various African languages, such as the Luo name ''mbuta'' or ''mputa''. In Tanzania, it is called '' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electric Catfish
Electric catfish or Malapteruridae is a family of catfishes (order Siluriformes). This family includes two genera, '' Malapterurus'' and ''Paradoxoglanis'', with 21 species. Several species of this family have the ability to generate electricity, delivering a shock of up to 350 volts from its electric organ. Electric catfish are found in tropical Africa and the Nile River. Electric catfish are usually nocturnal and carnivorous. Some species feed primarily on other fish, incapacitating their prey with electric discharges, but others are generalist bottom foragers, feeding on things like invertebrates, fish eggs, and detritus. The largest can grow to about 1.2 meters (3 ft) long, but most species are far smaller. Description The Malapteruridae are the only group of catfish with well-developed electrogenic organs; however, electroreceptive systems are widespread in catfishes. The electrogenic organ is derived from anterior body musculature and lines the body cavity. Electric catf ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Killifish
A killifish is any of various oviparous (egg-laying) cyprinodontiform fish (including families Aplocheilidae, Cyprinodontidae, Fundulidae, Profundulidae and Valenciidae). All together, there are 1,270 species of killifish, the biggest family being Rivulidae, containing more than 320 species. As an adaptation to living in ephemeral waters, the eggs of most killifish can survive periods of partial dehydration. Many of the species rely on such a diapause, since the eggs would not survive more than a few weeks if entirely submerged in water. The adults of some species, such as ''Kryptolebias marmoratus'', can additionally survive out of the water for several weeks. Most killies are small fish, from , with the largest species growing to just under . The word ''killifish'' is of uncertain origin, but is likely to have come from the Dutch ''kil'' for a kill (small stream). Although ''killifish'' is sometimes used as an English equivalent to the taxonomical term ''Cyprinodontidae'', s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chrysichthys
''Chrysichthys'' is a genus of claroteid catfishes native to Africa. Two fossil species are known. ''Chrysichthys macrotis'', Van Neer, 1994, is known from the Miocene-Pliocene of the Albertine Rift in Uganda and ''Chrysichthys mahengeensis'', Murray & Budney, 2003, is known from the Eocene of Mahenge, Tanzania. Species There are currently 42 recognized species in this genus: * ''Chrysichthys acsiorum'' Hardman, 2008 * ''Chrysichthys aluuensis'' Risch, 1985 * ''Chrysichthys ansorgii'' Boulenger, 1910 * ''Chrysichthys auratus'' ( É. Geoffroy Saint-Hilaire, 1809) * ''Chrysichthys bocagii'' Boulenger, 1910 * ''Chrysichthys brachynema'' Boulenger, 1900 (Kibonde, salmontail catfish) * ''Chrysichthys brevibarbis'' ( Boulenger, 1899) * ''Chrysichthys cranchii'' (Leach, 1818) (Kokuni, Kamba) * ''Chrysichthys dageti'' Risch, 1992 * ''Chrysichthys delhezi'' Boulenger, 1899 * ''Chrysichthys dendrophorus'' (Poll, 1966) * '' Chrysichthys depressus'' Nichols & Griscom, 1917) * '' Chrysi ...

Barbus
''Barbus'' is a genus of ray-finned fish in the family Cyprinidae. The type species of ''Barbus'' is the common barbel, first described as ''Cyprinus barbus'' and now named ''Barbus barbus''. ''Barbus'' is the namesake genus of the subfamily Barbinae, but given their relationships, that taxon is better included in the Cyprininae at least for the largest part (including the type species of ''Barbus''). Description and uses Their common names – barbs and barbels – refer to the fact that most members of the genera have a pair of barbels on their mouths, which they can use to search for food at the bottom of the water. Barbels are often fished for food; in some locations they are of commercial significance. The roe of barbels is poisonous, however. The large ''Barbus'' barbs are also often eaten in their native range. At Shanhûr in Egypt, remains of a jar from the sixth- to seventh-century AD were unearthed that contained fish bones. The fish were apparently pick ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mastacembelidae
The Mastacembelidae are a family of fishes, known as the spiny eels. The Mastacembelids are part of the Order Synbranchiformes, the swamp eels, which are part of the Actinopterygii (ray-finned fishes). In an evaluation of the family in 2004, the subfamilies of Mastacembelidae were found to not be well supported and were rejected. Also, the genera ''Caecomastacembelus'' and ''Aethiomastacembelus'' were placed in synonymy with ''Mastacembelus''. These fish originate from Africa, and southern and eastern Asia. Spiny eels generally inhabit soft-bottomed habitats in fresh and occasionally brackish water. Some species burrow in the substrate during the day or for certain months and have been found buried in soil in drying periods. These fish have an eel-like body. The largest species can reach a maximum length of . Very characteristic of this group is the long nose appendage with two tubulated nostrils. Mastacembelids have a series of well-separated dorsal spines on their back, hence ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Slender-snouted Crocodile
''Mecistops'' is a genus of crocodiles, the slender-snouted crocodiles, native to sub-Saharan Africa. Taxonomy and etymology Traditionally placed in ''Crocodylus'', recent studies in DNA and morphology have shown that it is in fact basal to ''Crocodylus'', thus was moved its own genus. This genus itself was long considered to contain only one species, '' M. cataphractus'', but recent genetic analysis has revealed the existence of two species: the West African slender-snouted crocodile (''M. cataphractus'') and the Central African slender-snouted crocodile (''M. leptorhynchus''). Both species diverged during the Miocene (about 6.5–7.5 million years ago) and are separated by the Cameroon Volcanic Line. Phylogeny The cladogram below is based on two studies that combined morphological and molecular (DNA sequencing) data. (Note that most morphological analyses find a closer relationship between ''Euthecodon'' and ''Brochuchus''.) Alternatively, other morphological studies h ...

History Of Portugal (1415–1542)
The history of Portugal can be traced from circa 400,000 years ago, when the region of present-day Portugal was inhabited by Homo heidelbergensis. The Roman invasion in the 3rd century BC lasted several centuries, and developed the Roman provinces of Lusitania in the south and Gallaecia in the north. Following the fall of Rome, Germanic tribes controlled the territory between the 5th and 8th centuries, including the Kingdom of the Suebi centred in Braga and the Visigothic Kingdom in the south. The 711–716 invasion by the Islamic Umayyad Caliphate conquered the Visigoth Kingdom and founded the Islamic State of Al-Andalus, gradually advancing through Iberia. In 1095, Portugal broke away from the Kingdom of Galicia. Henry's son Afonso Henriques proclaimed himself king of Portugal in 1139. The Algarve (the southernmost province in Portugal) conquered from the Moors in 1249, and in 1255 Lisbon became the capital. Portugal's land boundaries have remained almost unchanged since then. ...
