What are two unique coastal habitats?

Two unique coastal habitats are mangrove forests and coral reefs. Mangrove forests, found in tropical and subtropical regions, are characterized by salt-tolerant trees that provide crucial nursery grounds for various marine species and protect Coastlines from erosion. Coral reefs, often referred to as the "rainforests of the sea," are biodiverse ecosystems formed by coral polyps that build calcium carbonate structures, supporting a myriad of marine life and serving as vital barriers against storm surges. Both habitats play essential roles in marine biodiversity and coastal protection.
