Out of many corals which face survival risk because of rising acidity of the oceans, Caribbean coral species can survive and grow under the rising carbon dioxide levels, found researchers.A new study published in the journal of Biological Sciences showed that at least three Caribbean coral species can survive and grow under conditions of ocean acidification more severe than those expected to occur during this century, although the density of their skeletons was lower than normal.The study took advantage of the unusual seawater chemistry found naturally at sites along the Caribbean coastline of Mexico's Yucatan Peninsula, where water discharging from submarine springs has lower pH than the surrounding seawater, with reduced availability of the carbonate ions corals need to build their calcium carbonate skeletons.In a two-year field experiment, the international team of researchers transplanted genetically identical fragments of three species of corals to a site affected by the springs .
