As corals grow, branches, boulders, plates, and polyps, all become home for something smaller. Coral reefs are believed by many to have the highest biodiversity of any ecosystem on the planet—even more than a tropical rainforest. Because of the diversity of life found in the habitats created by corals, reefs are often called the "rainforests of the sea." Coral reefs are made predominantly of stony corals and supported by the limestone skeleton they excrete. By restoring corals at seven iconic reef sites in Florida Keys National Marine Sanctuary, we can change the trajectory of an entire ecosystem and help save one of the world’s most unique areas for future generations. That carbon acts as a heat-trapping blanket, keeping the heat from the sun close to the planet and warming the atmosphere and the ocean. Scientists estimate that more than one million species of plants and animals are associated with coral reef ecosystems. Bleaching can happen when water temperature increases, and because our climate is changing, the water throughout the ocean is getting too warm for many coral species. | Office of National Marine Sanctuaries Coral reefs support 25% of life in the ocean -- but they need our help.

Looking at those models, the scientists found that most parts of the ocean will not sustain habitats for corals by 2045, and almost no suitable habitats will exist by 2100. Coral reefs are feeling the heat from climate change. Aside from the hundreds of species of coral, reefs support extraordinary biodiversity and are home to a multitude of different types of fish, invertebrates and sea mammals.
