Corals, the primary reef builders on coral reefs, are often the star player in research studies addressing the impacts of climate change on coral reefs because they are the foundation of coral reef ecosystems. However, the breakdown of coral reefs from borers (such as bivalves, sponges, and marine worms) and grazers (such as parrotfish and urchins) -- called bioerosion -- and growth from encrusting algae and invertebrates (for example, oysters and barnacles) -- called secondary accretion -- are critical processes for reef sustainability.
What is bioerosion? What is the link between coral reefs and ocean acidification? What is ocean acidification?
