What are the differences between mangroves and coral reef?

Mangroves are coastal trees or shrubs that grow in saline habitats, providing nurseries for fish and protecting shorelines from erosion. Coral reefs are underwater ecosystems composed of coral polyps that provide habitat for a diverse range of marine organisms. While both mangroves and coral reefs are important coastal ecosystems, they differ in their physical structure, location, and the types of species they support.
