Our work focuses on the underlying communication network in animal swarms that enables coordinated movement and collective information processing in large groups while taking into account the limited attention and cognitive ability of each individual. Here, we study the influence of network structure on processes of behavioral complex contagion in fish groups. Specifically, we investigate the spreading of startling behavior in golden shiners on empirically inferred networks built on their individual visual perception of neighbors [1]. Using a simple adapted SIR model [2] we aim to uncover how the spatial configuration of a swarm (and thus its visual interaction network) aid to amplify or dampen out the information send out by a certain individual.
