Sepia Hierredda
''Sepia hierredda'', the giant African cuttlefish, is a species of cuttlefish from the family Sepiidae, which was previously considered conspecific with the common cuttlefish ''Sepia officinalis''. It is found along the western coast of Africa and is an important species to fisheries. Description ''Sepia hierredda'' is very similar to the common cuttlefish but there are a number of consistent morphological differences which can be used to identify ''S. hieredda'' from ''S. officinalis'', the two species being sympatric off northwestern Africa. The colour pattern shown by ''S. hierredda'' is very similar to that of ''S. officinalis''. The morphological features that distinguishing this species from the common cuttlefish are that in ''S.hierraedda'' the number of transverse rows of suckers is higher, for specimens of similar mantle lengths, the striated zone on the cuttlebone of common cuttlefish from the northeastern Atlantic is shorter than the same feature in ''S. hierredda'' ...

Sander Rang
Sander Rang or Paul Charles Leonard Alexander Rang (1793, Utrecht -1844, Mayotte) was a French conchologist and interpreter of Arabic texts. He was, in 1816, one of the survivors of the sinking of the frigate ''Medusa'', on which he was an ensign. He spent a good part of his life in La Rochelle, where he published his early zoological observations, in particular in the bulletins of the Society of Natural Sciences of Charente-Maritimes.In 1841 Rang was one of the founding members of the Société des Amis des Arts now the Musée des Beaux-Arts de La Rochelle.He specialised in marine fauna notably in sea hares, cephalopods and other molluscs and on the heterogenous group known as zoophytes. Sander Rang described many new mollusc species including the sea hares ''Aplysia dactylomela'', '' Dolabrifera dolabrifera'', the cuttlefish ''Sepia hierredda'' and the land snails ''Striosubulina striatella'', '' Pleurodonte desidens '' and ''Opeas hannense''.

Canary Islands
The Canary Islands (; es, Canarias, ), also known informally as the Canaries, are a Spanish autonomous community and archipelago in the Atlantic Ocean, in Macaronesia. At their closest point to the African mainland, they are west of Morocco. They are the southernmost of the autonomous communities of Spain. The islands have a population of 2.2 million people and they are the most populous special territory of the European Union. The seven main islands are (from largest to smallest in area) Tenerife, Fuerteventura, Gran Canaria, Lanzarote, La Palma, La Gomera, and El Hierro. The archipelago includes many smaller islands and islets, including La Graciosa, Alegranza, Isla de Lobos, Montaña Clara, Roque del Oeste, and Roque del Este. It also includes a number of rocks, including those of Salmor, Fasnia, Bonanza, Garachico, and Anaga. In ancient times, the island chain was often referred to as "the Fortunate Isles". The Canary Islands are the southernmost region of Spain, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fishing Trawler
A fishing trawler is a commercial fishing vessel designed to operate Trawling, fishing trawls. Trawling is a method of fishing that involves actively dragging or pulling a trawl through the water behind one or more trawlers. Trawls are fishing nets that are pulled along the bottom of the sea or in midwater at a specified depth. A trawler may also operate two or more trawl nets simultaneously (double-rig and multi-rig). There are many variants of trawling gear. They vary according to local traditions, bottom conditions, and how large and powerful the trawling boats are. A trawling boat can be a small open boat with only 30 horsepower (22 kW) or a large factory ship with 10,000 horsepower (7457 kW). Trawl variants include beam trawls, large-opening midwater trawls, and large bottom trawls, such as "rock hoppers" that are rigged with heavy rubber wheels that let the net crawl over rocky bottom. History During the 17th century, the British developed the Dogge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mauritania
Mauritania (; ar, موريتانيا, ', french: Mauritanie; Berber: ''Agawej'' or ''Cengit''; Pulaar: ''Moritani''; Wolof: ''Gànnaar''; Soninke:), officially the Islamic Republic of Mauritania ( ar, الجمهورية الإسلامية الموريتانية), is a sovereign country in West Africa. It is bordered by the Atlantic Ocean to the west, Western Sahara to the north and northwest, Algeria to the northeast, Mali to the east and southeast, and Senegal to the southwest. Mauritania is the 11th-largest country in Africa and the 28th-largest in the world, and 90% of its territory is situated in the Sahara. Most of its population of 4.4 million lives in the temperate south of the country, with roughly one-third concentrated in the capital and largest city, Nouakchott, located on the Atlantic coast. The country's name derives from the ancient Berber kingdom of Mauretania, located in North Africa within the ancient Maghreb. Berbers occupied what is now Mauritania ...

Western Sahara
Western Sahara ( '; ; ) is a disputed territory on the northwest coast and in the Maghreb region of North and West Africa. About 20% of the territory is controlled by the self-proclaimed Sahrawi Arab Democratic Republic (SADR), while the remaining 80% of the territory is military occupation, occupied and administered by neighboring Morocco. Its surface area amounts to . It is one of the List of sovereign states and dependent territories by population density, most sparsely populated territories in the world, mainly consisting of desert flatlands. The population is estimated at just over 500,000, of which nearly 40% live in Laayoune, the largest city in Western Sahara. Occupied by Spain until 1975, Western Sahara has been on the United Nations list of non-self-governing territories since 1963 after a Moroccan demand. It is the most populous territory on that list, and by far the largest in area. In 1965, the United Nations General Assembly adopted its first resolution on Wes ...

Endeavour Bank
Echo Bank (also known as Endeavour Bank) is an underwater mountain, part of Canary Islands Seamount Province and located southwest of the Canary Islands. Of uncertain geologic origin, it is part of a larger cluster of submarine mountains and rises to a depth of below sea level. It has a flat top, indicating that it formerly might have emerged from the sea. Name The etymology of "Echo Bank" is unknown but it is also known as Endeavour Bank and the name "Echo Bank" might refer to a submarine feature discovered in 1925-1927 and so named after its reflective crest. Geography and geomorphology Regional Echo Bank is part of the Canary Islands Seamount Province (CISP), which reaches from north of Lanzarote in the Canary Islands to southwest of the archipelago. This province aside from Echo Bank includes Tropic Seamount, The Paps Seamount, Ico Seamount and Drago Seamount but also Essaouira Seamount north of Lanzarote.

Baia Dos Tigres
The Tigres Strait, formerly known as Tigres Bay or Great Fish Bay, is a strait in Angola, located in Namibe Province, serving as a separation between the Angolan mainland and the Tigres Island. Geography It once had a small peninsula on its eastern side, with its isthmus in the south and a well established fishing village named Saint Martin of the Tigers (in Portuguese: ''São Martinho dos Tigres''). The ocean broke through the isthmus of the peninsula in 1962 and the water line was severed. Tigres became an island overnight, Tigres Island, the largest island of Angola. Currently, most of the area of the former bay has become a strait between the island and the mainland. Of the original bay, only a small inlet open to the north —the ''Saco dos Tigres''— remains at the southern end. See also * Geography of Angola Angola is located on the western Atlantic Coast of Southern Africa between Namibia and the Republic of the Congo. It also is bordered by the Democratic Republic o ...

Ras Nouadhibou
Ras Nouadhibou ( ar, رأس نواذيبو) is a peninsula or headland divided by the border between Mauritania and Western Sahara on the African coast of the Atlantic Ocean. It is internationally known as ''Cabo Blanco'' in Spanish or ''Cap Blanc'' in French (both meaning "White Headland"). In the 14th and 15th centuries, fishing activities carried out from the nearby Canary Islands, by Spanish fishermen, inspired Spain to develop an interest in the desert coast of what is today called Western Sahara. Cabo Blanco, in the Atlantic Ocean, is the only place in the world where Mediterranean monk seals form a true colony. In 1997, two-thirds of the colony died off, but there has been gradual recovery since. Geography The headland forms the western limit of Dakhlet Nouadhibou Bay. This thin stretch of land is divided between Mauritania and Western Sahara. On the western side lies the ghost town of La Güera; on the eastern side, less than from the border, lies Mauritania's No ...

Vernacular Name
A vernacular or vernacular language is in contrast with a "standard language". It refers to the language or dialect that is spoken by people that are inhabiting a particular country or region. The vernacular is typically the native language, normally spoken informally rather than written, and seen as of lower status than more codified forms. It may vary from more prestigious speech varieties in different ways, in that the vernacular can be a distinct stylistic register, a regional dialect, a sociolect, or an independent language. Vernacular is a term for a type of speech variety, generally used to refer to a local language or dialect, as distinct from what is seen as a standard language. The vernacular is contrasted with higher-prestige forms of language, such as national, literary, liturgical or scientific idiom, or a ''lingua franca'', used to facilitate communication across a large area. According to another definition, a vernacular is a language that has not develope ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hybridisation (biology)
In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different breeds, varieties, species or genera through sexual reproduction. Hybrids are not always intermediates between their parents (such as in blending inheritance), but can show hybrid vigor, sometimes growing larger or taller than either parent. The concept of a hybrid is interpreted differently in animal and plant breeding, where there is interest in the individual parentage. In genetics, attention is focused on the numbers of chromosomes. In taxonomy, a key question is how closely related the parent species are. Species are reproductively isolated by strong barriers to hybridisation, which include genetic and morphological differences, differing times of fertility, mating behaviors and cues, and physiological rejection of sperm cells or the developing embryo. Some act before fertilization and others after it. Similar barriers exist in plants, with differences in flowering tim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
