Marine Biologists Unmask Species Diversity in Coral Reefs
Two corals (Porites sp.) growing side by side.The left colony is bleached: it appears white. During bleaching the partnership between symbiotic algae that live inside the coral cells and the coral host breaks down giving the coral a white appearance. The colony on the right is still green/brown and has a healthy population of symbionts living in its tissue. Photo credit: Iliana Baums, Penn State University.
