Although reefs occupy only around 0.2% of the ocean's area, they are a fundamental part of oceanic ecosystems. Geologically, reefs strongly influence local sedimentation and geomorphology. Biologically, they provide a habitat for a huge variety of species. The varied environments provided by reefs have made them into major sites for species origination. For these reasons, the origin of reef building among animals, and its early ecological significance, are important topics in the history of life.
