Divers feed sea urchins to local fish, which in turn act as guides, leading divers to the largest and most abundant urchin populations as a reward-based exchange.

The Arai hawkfish leads divers to sea urchins that threaten its algae home. By guiding the diver to remove these pests, the fish uses the diver to perform difficult maintenance on its reef territory.
