Chapter three – Behavioral impacts of ocean acidification on marine animals

Behavioral modification is the distinct response exhibited by marine animals to stressors. Exposure to oceanic environmental changes can alter the behaviors of aquatic animals, such as foraging, antipredation, habitat selection, and social hierarchy. Ocean acidification (OA) can alter the animal behaviors of a single species and thereby affect the structure and function of marine populations, communities, and ecosystems. Recently, the effects of OA on the behavioral responses of marine animals have received much attention. Considering the essential ecological functions and fishery value of marine living resources, we need to remain vigilant about the subsequent risk of OA. Here, we provide a systematic review including some classical case studies to highlight the effects of CO2-driven OA on the most common behaviors studied in marine animals and synthesize the current understanding of how OA may impact marine animal behaviors.
