Coral reefs are the most diverse habitats on the planet. They serve as homes for thousands of species of marine life and people rely on them for food, coastal protection, and jobs.

We're celebrating corals on our social media channels from December 9-13, 2024. We hope you join us on Twitter, Facebook, and Instagram. Look for #CoralsWeek.
