Humbug damselfish offer researchers a natural system for studying how threat information propagates through a group without every fish independently detecting the danger.
University of Washington researchers are recording wild schools on Maldivian coral reefs with synchronized cameras and automated tracking to examine how responses spread from fish to fish, how schools distinguish genuine threats from false alarms, and how individuals collectively coordinate the transition back to normal behaviour once danger has passed. The work also asks whether reef degradation disrupts these communication dynamics.
