Reef Ecosystems

Reef ecosystems are a type of underwater environment that supports a diverse range of species and habitats, and play a significant role in the global marine environment. Reefs form when corals, seaweeds and calcareous algae attach to rock or the remains of their predecessors, building complex structures that provide shelter and food for many species of fish, crustaceans, molluscs, and other creatures. The rich biodiversity of reef ecosystems creates an ideal habitat for a variety of organisms, promoting biodiversity and resiliency of the marine environment. In addition to providing a habitat for a variety of species, reef ecosystems are also important for supporting many of the world’s fisheries, acting as nurseries for juvenile fish, providing coastal protection, and contributing to local economies through tourism and fishing. As the effects of climate change and other human impacts threaten the health of the world’s reefs, it is vitally important to maintain and restore these valuable ecosystems.
