    Summary
    We examined the modulatory role of serotonin in cooperation between unrelated individuals. The identification of the neurohormonal candidates that may modulate levels of cooperation in marine cleaning mutualisms has been a major aim in recent years. Our results provide evidence that serotonin is a driver of cooperative behavioral activities and contribute to the understanding of neural pathways of cooperation, which aim to unravel the basic drive of animal tendencies to cooperate with others
