1999; Ngo-Massou et al. 2012). However, these works have provided relevant data
concerning essentially the distribution of molluscs in the Cameroon Atlantic coast
(Table 3.2). A relative recent census found 12 species among which 11 gastropods
and one unknown species of bivalves (Ngo-Massou et al. 2012).
Throughout most mangrove habitats, molluscs live on and in the muds, firmly
attached to the roots, or forage in the canopy. They occupy a number of niches and
contribute to the ecology of the mangal in important ways (Kathiresan and Bingham
2001). The composition of molluscan community in Wouri estuary river mangrove
forest consist of two main taxa as Gastropods and Bivalves (Fig. 3.7).
