specie is common in rainy season. Since several years, the manatee is faced to many
threats (Ayissi and Jiofack 2014). The carnivores are rather rare; all the species of
monkeys are arboreal. The existence of Whales and Dolphins along Cameroon coast
is known, but the species distribution is unknown (Ayissi et  al. 2011). Whereas
some species can be more or less frequently observed, others are much rare and
make only incursions of short duration into the mangrove forest.
Mangrove waterways are rich fishing grounds and many commercial species can
be found. The most frequently encountered species are: Ilisha africana, Sardinella
maderensis, Caranx spp., Tilapia spp., Dentex congolensis, Arius spp., Pomadasys
spp. and Periophtalmus papilio, the mud skippers (Fig. 3.8).
