Phytoplankton and Zooplankton? Marine Animals? What regions of the ocean will be affected first? References used in this section How will ocean acidification affect marine life? Corals, calcareous phytoplankton, mussels, snails, sea urchins and other marine organisms use calcium (Ca) and carbonate (CO3) in seawater to construct their calcium carbonate (CaCO3) shells or skeletons. As the pH decreases, carbonate becomes less available, which makes it more difficult for organisms to secrete CaCO3 to form their skeletal material. For animals in general, including invertebrates and some fish, CO2 accumulation and lowered pH may result in acidosis, or a build up of carbonic acid in the organism's body fluids. This can lead to lowered immune response, metabolic depression, behavioural depression affecting physical activity and reproduction, and...
