Ocean Acidification and Coral Reef Loss: Impact on Reef Fish Behavior

New research indicates that ocean acidification is disrupting the social structures of reef fish. While chemical changes affect marine life, the loss of physical coral habitats is the primary driver causing fish to form smaller shoals and exhibit more cautious, isolated behavior. These behavioral shifts increase vulnerability to predators and threaten the stability of marine biodiversity. Because coral reefs support nearly 25% of marine species, the collapse of these social networks could lead to cascading ecological failures across the ocean.
