Gastropod Shell
The gastropod shell is part of the body of a Gastropoda, gastropod or snail, a kind of mollusc. The shell is an exoskeleton, which protects from predators, mechanical damage, and dehydration, but also serves for muscle attachment and calcium storage. Some gastropods appear shell-less (slugs) but may have a remnant within the mantle, or in some cases the shell is reduced such that the body cannot be retracted within it (semi-slug). Some snails also possess an operculum that seals the opening of the shell, known as the Aperture (mollusc), aperture, which provides further protection. The study of mollusc shells is known as conchology. The biological study of gastropods, and other molluscs in general, is malacology. Shell morphology terms vary by species group. Shell layers The gastropod shell has three major layers secreted by the Mantle (mollusc), mantle. The calcareous central layer, tracum, is typically made of calcium carbonate precipitated into an organic matrix known as c ...

Terrestrial Molluscs
Terrestrial molluscs or land molluscs (mollusks) are an ecological group that includes all molluscs that live on land in contrast to freshwater and marine molluscs. They probably first occurred in the Carboniferous, arising from freshwater ones. Characteristics This group includes land snails and land slugs. Loss of the shell has taken place many times in different groups that are not evolutionarily closely related, and land snails and slugs are most often treated together as a single group in specialized malacological literature.Barker G. M. (ed.) The biology of terrestrial molluscs'. CABI Publishing, 2001, 558 pp. .Barker G. M. (ed.) Natural enemies of terrestrial molluscs'. CABI Publishing, 2004, 644 pp. . All terrestrial molluscs belong to the class Gastropoda. However, colonization of the land took place several times during the evolutionary past, and as a result terrestrial molluscs are classified in several different, often not closely related, gastropod taxa.

Liberia
Liberia (), officially the Republic of Liberia, is a country on the West African coast. It is bordered by Sierra Leone to Liberia–Sierra Leone border, its northwest, Guinea to its north, Ivory Coast to its east, and the Atlantic Ocean to its south and southwest.

The country's capital and largest city is Monrovia. Liberia began in the early 19th century as a project of the American Colonization Society (ACS), which believed black people would face better chances for freedom and prosperity in Africa than in the United States. Between 1822 and the outbreak of the American Civil War in 1861, more than 15,000 freed and free-born black people who faced social and legal oppression in the U.S., along with 3,198 Afro-Caribbeans, relocated to Liberia.

Zaire
Zaire (, ), officially the Republic of Zaire (french: République du Zaïre, link=no, ), was a Congolese state from 1971 to 1997 in Central Africa that was previously and is now again known as the Democratic Republic of the Congo.

With a population of over 23 million inhabitants, Zaire was the most-populous officially Francophone country in Africa, as well as one of the most populous in Africa. The country was a one-party totalitarian military dictatorship, run by Mobutu Sese Seko and his ruling Popular Movement of the Revolution party. Zaire was established following Mobutu's seizure of power in a military coup in 1965, following five years of political upheaval following independence from Belgium known as the Congo Crisis. Zaire had a strongly centralist constitution, and foreign assets were nationalized. The period is sometimes referred to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cameroon
Cameroon (; french: Cameroun, ff, Kamerun), officially the Republic of Cameroon (french: République du Cameroun, links=no), is a country in west-central Africa.

Its coastline lies on the Bight of Biafra, part of the Gulf of Guinea and the Atlantic Ocean. Due to its strategic position at the crossroads between West Africa and Central Africa, it has been categorized as being in both camps. Its nearly 27 million people speak 250 native languages. Early inhabitants of the territory included the Sao civilisation around Lake Chad, and the Baka hunter-gatherers in the southeastern rainforest. Portuguese explorers reached the coast in the 15th century and named the area ''Rio dos Camarões'' (''Shrimp River''), which became ''Cameroon'' in English.

São Tomé
São Tomé is the capital and largest city of the Central African island country of São Tomé and Príncipe. Its name is Portuguese for " Saint Thomas". Founded in the 15th century, it is one of Africa's oldest colonial cities. History Álvaro Caminha founded the colony of São Tomé in 1493. The Portuguese came to São Tomé in search of land to grow sugarcane. The island was uninhabited before the arrival of the Portuguese sometime around 1470. São Tomé, situated about north of the equator, had a climate wet enough to grow sugarcane in wild abundance. 2,000 Jewish children, eight years old and under, were taken from the Iberian peninsula for work on the sugar plantations. The nearby African Kingdom of Kongo eventually became a source of slave labor as well. The island of São Tomé was the main center of sugar production in the sixteenth century; it was overtaken by Brazil by 1600. São Tomé is centred on a sixteenth-century cathedral, that was largely rebuilt in th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Archachatina Bicarinata
''Archachatina bicarinata'', the Obô giant snail, or black snail, is a species of air-breathing tropical land snail, a terrestrial pulmonate gastropod mollusk in the family Achatinidae. Description The shell of ''A. bicarinata'' can reach a length of . This giant shell is always sinistral or reverse-coiled (hence the synonym ''A. sinistrorsa''). Distribution This species is endemic to São Tomé and Príncipe, off the west coast of Africa in the Gulf of Guinea. Habitat The Obô giant snail lives in the primary rainforest on the mountains. It suffers from habitat loss, the mass collection of the shells and harvesting the snails for food. The species got largely displaced by the smaller West African giant land snail (Archachatina marginata The giant West African snail or banana rasp snail (''Archachatina marginata'') is a species of air-breathing tropical land snail, a terrestrial pulmonate gastropod mollusk in the family Achatinidae.
