Using social groups (i.e. schools) of the tropical damselfish Chromis viridis, we tested how familiarity through repeated social interactions influences fast-start responses, the primary defensive behaviour in a range of taxa, including fish, sharks, and larval amphibians. We focused on reactivity through response latency and kinematic performance (i.e. agility and propulsion) following a simulated predator attack, while distinguishing between first and subsequent responders (direct response to stimulation versus response triggered by integrated direct and social stimulation, respectively). In familiar schools, first and subsequent responders exhibited shorter latency than unfamiliar individuals, demonstrating that familiarity increases reactivity to direct and, potentially, …
