Coral Reefs | Microschool Dev

Coral reefs are underwater ecosystems characterized by reef-building corals. These structures are formed by colonies of coral polyps held together by calcium carbonate. Reefs support an incredible diversity of marine life, acting as nurseries, feeding grounds, and shelter for a quarter of all ocean species. Despite their ecological importance, coral reefs face severe threats from climate change, pollution, and destructive fishing practices, leading to widespread degradation and loss.
