Corals are tiny animals called popyps which secrete limestone as a skeleton. They divide as they grow and form coral colonies.

Naturel Dammage

Today this little paradise is in danger, because the reefs found there are disturbed by natural events such as hurricanes and tropical storms or by disease or predators like the crown-of-thorn starfish that feeds the corals .
