Tropical marine ecosystems are extremely rich in biodiversity and include coral reefs, mangrove forests, seagrass and algae meadows and of course, the infinite open sea. These areas not only maintain biodiversity and provide all necessary for tropical community, but also support extensive tourist activities in various parts of the world. Organisms such as corals, mangroves and seagrass are the foundation of this community, protecting it from coastal erosion and acting as a filtration system to purify the surrounding water. In addition, those biologically created habitats serve as breeding ground for many species of invertebrates and fish.
