Explore how a coral reef ecosystem changes over the course of a day. When the sun is up, colorful fish and other plant-eating animals are active and dominate the reef. At night, the plant-eaters take shelter and are replaced by nocturnal carnivores, some of which exhibit special adaptations that enable them to successfully hunt in complete darkness.
