However, reefs and mangroves are often found together and may be closely linked. Mangroves protect reefs from terrestrial sediments and provide shelter among their roots for juvenile reef fish, such as snappers.
Coral reefs protect mangroves and seagrasses fromerosion during storms and strong wave action.
Seagrass beds are another important tropical marine habitat, stabilising sediments and providing an important food source for many reef species. On Guadeloupe, reefs and mangroves are closely inter-linked, particularly in the Grand Cul de Sac Marin on the north coast. This large bay has extensive mangroves, seagrasses and patch reefs protected by a barrier reef.
