The marine coastal ecosystems, just like the coral reefs, the seagrass meadows and the mangroves interact with each other and are of great importance in the tropical oceans because of their biodiversity. These ecosystems are the base for fishery production and tourism. They contribute to the protection of the coastlines from erosion processes. The coral reefs form barriers that disperse the energy of waves and storms, creating appropriate conditions for mangroves and meadows to establish themselves, as a result the mangroves improve the transparency of the water because they act as traps to materials that come from dryland.
