Cameroun. There are other smaller rocky beaches and between them are sandy beaches, which may be small, or extensive (Yankson and Kendall, 2001). On the coast of Ghana for instance, the greatest extent of almost continuous rock shore is on either side of Cape Three Points and stretches from the Ankobra River in the west to Sekondi in the east, a distance of about 45 miles. The west of the Ankobra is characterized by sandy beaches extending through Ivory Coast. Also, between Takoradi and Prampram, 150 miles to the east, sandy shores dominate but rocky shores of limited extent occur in several places, notably in the region of Cape Coast and Elmina and in the Accra area. At the east of Prampram, sandy beaches stretch almost continuously along the eastern coast of Ghana and throughout Nigeria until a rocky shore is met with again in the Cameroons (Gauld and Buchanan, 1959). Various surveys of the West African seashore have found barnacles and gastropods dominating the invertebrate community (Gauld and Buchanan, 1959; Yankson and Akpabey, 2001; Yankson and Kendall, 2001; Lamptey, Armah and Allotey, 2009). Three species of barnacles, namely Cthamalus dentatus, Megabalanus tintinnabulum and Tetraclita squamata are found on the West African rocky shores. C. dentatus is the common barnacle of open coasts. They have a kite shaped opening to the shell. Six plates are clearly visible in isolated individuals. The plates have projecting ribs giving the animal a star-shaped outline. Recently settled animals are a pale brown color but as they age, they quickly become dirty white. C. dentatus have no calcareous base between the body of the animal and the rock surface (Edmunds, 1978; Yankson and Kendall, 2001). Tetraclita squamata tends to be conical in shape and can reach a large size (25mm or more in length). Unlike Chthamalus species, it does not occur in vast sheets of interlocking animals. The plates making up the shell become fused as the animal grows and in large specimens can be difficult to distinguish. The plates are perforated by rows of fine holes. This species is often heavily overgrown by algae (Yankson and Kendall, 2001). Megabalanus tintinnabulum is found worldwide and has been described on this site. The most common hermit crabs on this shore are Clibernarius chapini and Clibernarius senegalensis. Identification of species is complex but the common rule is C. chapini occurs mostly in long turreted gastropod shells while
