Most corals consist of many small polyps living together in a large group. This image shows cells that make up the tentacles and wall of a single polyp; part of the polyp’s mouth is visible in the upper left. Images like this one are used to understand how corals coevolved with algae to optimize the harvesting of light from seawater, and to help predict how corals will respond to global climate change.
