Since the Industrial Revolution, the massive amount of anthropogenic carbon dioxide (CO2) generated has elevated the atmospheric CO2 concentration. About one-fourth to one-third of the anthropogenic CO2 has been absorbed by the ocean, which leads to reductions in both oceanic pH and carbonate ion concentrations, a process known as “ocean acidification” (OA). Theoretically, OA will pose a great threat to a variety of marine invertebrates by influencing the skeletal formation and the chemical properties of habitats. Since invertebrates play a significant role in the marine ecosystem and many marine invertebrates are economically important aquaculture species, the effects of OA on marine invertebrates have been a hotspot for research in recent years. In this chapter, the current knowledge of the physiological influences of OA on marine invertebrates, including gametic traits, fertilization success, embryonic development, biomineralization, metabolism, growth, and immune responses, was summarized. In addition, the potential underlying affecting mechanisms were discussed. The authors hope that the contents of this chapter provide some basic information and guidance for readers who are interested in this area and plan to carry out future studies on this topic.
