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. They can grow up to long, and live up to 10 years or more. Distribution This species occurs in Western Africa (Cameroon to the Democratic Republic of the Congo) and the Caribbean (Martinique). How the species reached Martinique is unknown, but they may have been intentionally introduced as "pets" or by workers returning from West Africa. The natural spread of this species is very slow; however, unintentional spread by individuals for food and as folk medicine is very common. The USDA routinely checks for the species in the luggage of travelers from West Africa, Nigeria particularly, Ghana, and Cameroon. This species has not yet become established in the United States, but it is considered to represent a potentially serious threat as a pest, an invasive species that could neg ...

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.

Achatinidae
Achatinidae (New Latin, from Greek "''agate''") is a family of medium to large sized tropical land snails, terrestrial pulmonate gastropod mollusks from Africa. Well known species include ''Achatina achatina'' the Giant African Snail, and ''Lissachatina fulica'' the Giant East African Snail. As of 2022, there were 105 genera recognized within the family Achatinidae. Description In this family, the number of haploid chromosomes lies between 26 and 30 (according to the values in this table).Barker G.

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 ...

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. It has a population of around 5 million and covers an area of . English is the official language, but over 20 indigenous languages are spoken, reflecting the country's ethnic and cultural diversity. 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.
