The mangrove is a habitat for many animal species of molluscs, crustaceans and fish and therefore a vast feeding area for birds and a privileged place for gathering and fishing. Its brackish water allows the development of a mixed aquatic fauna of freshwater fish supporting the influence of the tides and lagoon species resistant to desalinated water. The mangrove murky water and root system also provide a refuge area for juveniles and small species whom they protect from predators. The mangrove roots are finally an ideal support for many fixed animals (oysters, clams, mussels, sponges, sea squirts) and algae.
