Raising Coral Costa Rica aims to help rebuild the rainforests of the sea

Coral reefs are known as the rainforests of the sea for their extraordinary biodiversity.

These breathtaking underwater structures are created by a legion of tiny mega builders called coral polyps, small invertebrate animals with flagellating tentacles. Each coral colony is formed by interconnected polyps, all clones of each other, that secrete calcium carbonate to produce the beautiful white rock-like skeletons that lies beneath them.
