Coral reefs, vibrant marine ecosystems, provide habitats for diverse species. Despite their appearance, corals are animals that grow slowly, forming extensive reefs over generations. The Great Barrier Reef is the largest, hosting numerous marine species. Reefs support complex interactions, like cleaning stations and predator-prey dynamics. However, they face threats from global warming, pollution, and overfishing. Conservation efforts, including artificial reefs, aim to protect these vital ecosystems.
