It was also the traditional sidearm of the Highland Clansman and later used by the officers, pipers, and drummers of Scottish Highland regiments around 1725 to 1800 and by Japanese naval officers.

Claroteid Catfish
The Claroteidae are a family of catfish (order Siluriformes) found in Africa. This family was separated from Bagridae. However, the monophyly of the family is sometimes contested. The 12 genera contain 86 known species of claroteids in two subfamilies, Claroteinae and Auchenoglanidinae. The subfamily Auchenoglanidinae is sometimes classified as a separate family Auchenoglanididae. This group was also often formerly placed in Bagridae. The monophyly of Auchenoglanidinae is uncontested; it contains the three genera ''Auchenoglanis'', ''Parauchenoglanis'' and ''Notoglanidium''. Two commonly known species are the giraffe catfish, ''Auchenoglanis occidentalis'', and the African big-eye catfish, ''Chrysichthys longipinnis''. Claroteids have moderately elongated bodies, usually with four pairs of barbels, an adipose 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 eit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ogooué River
The Ogooué (or Ogowe), also known as the Nazareth river, some long, is the principal river of Gabon in west central Africa and the fifth largest river in Africa by volume of discharge, trailing only the Congo, Kasai, Niger and Zambezi. Its watershed drains nearly the entire country of Gabon, with some tributaries reaching into the Republic of the Congo, Cameroon, and Equatorial Guinea. Course The source of the Ogooué River was discovered in 1894 by Mary Kingsley, an English explorer who travelled up the banks by steamboat and canoe. The river rises in the northwest of the Bateke Plateaux near Kengue, Republic of Congo. It runs northwest, and enters Gabon near Boumango. Poubara Falls are near Maulongo. From Lastoursville up to Ndjole, the Ogooué is non-navigable due to rapids. From the latter city, it runs west, and enters the Gulf of Guinea near Ozouri, south of Port Gentil. The Ogowe Delta is quite large, about 100 km long and 100 km wide. Basin Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gabon
Gabon (; ; snq, Ngabu), officially the Gabonese Republic (french: République gabonaise), is a country on the west coast of Central Africa. Located on the equator, it is bordered by Equatorial Guinea to the northwest, Cameroon to the north, the Republic of the Congo on the east and south, and the Gulf of Guinea to the west. It has an area of nearly and its population is estimated at million people. There are coastal plains, mountains (the Cristal Mountains and the Chaillu Massif in the centre), and a savanna in the east. Since its independence from France in 1960, the sovereign state of Gabon has had three presidents. In the 1990s, it introduced a multi-party system and a democratic constitution that aimed for a more transparent electoral process and reformed some governmental institutions. With petroleum and foreign private investment, it has the fourth highest HDI in the region (after Mauritius, Seychelles and South Africa) and the fifth highest GDP per capita ( ...

Kouilou River
The Kouilou-Niari River—also spelled Kwilu, Kwila, or Kwil—is the most important river flowing to the Atlantic Ocean of the Republic of the Congo coast. Moreover, its entire drainage area is completely in the Republic of the Congo. The river is called the Kouilou River while flowing in the coastal region of the Kouilou till the Sounda gorges. Upstream from the gorges, its name is the Niari River and it flows through the Niari Valley. The river combines with the Louessé, the Loudima and the Bouenza River and eventually flows into the Atlantic Ocean. It covers about 560 km from its origin in the Batéké Plateau of the Congo to its mouth at the coast. The river has numerous waterfalls and is impassable from its mouth, which is of difficult access by multiple sandbars, formed primarily by the action of the Benguela current. The river is usable and boats are coming up to Kakamoéka. From Kakamoéka to Sounda, rapids and rocks are blocking access especially during d ...

Republic Of The Congo
The Republic of the Congo (french: République du Congo, ln, Republíki ya Kongó), also known as Congo-Brazzaville, the Congo Republic or simply either Congo or the Congo, is a country located in the western coast of Central Africa to the west of the Congo river. It is bordered to the west by Gabon, to its northwest by Cameroon and its northeast by the Central African Republic, to the southeast by the Democratic Republic of the Congo, to its south by the Angolan exclave of Cabinda Province, Cabinda and to its southwest by the Atlantic Ocean. The region was dominated by Bantu peoples, Bantu-speaking tribes at least 3,000 years ago, who built trade links leading into the Congo River basin. Congo was formerly part of the French colonial empire, French colony of French Equatorial Africa, Equatorial Africa. The Republic of the Congo was established on 28 November 1958 and gained independence from France in 1960. It was a Marxist–Leninist state from 1969 to 1992, under the name ...

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 (shark Sharks are a group of elasmobranch fish chara ...

Fish Of Africa
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 placodermi, 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 arthropo ...
