The coral skeleton and its optical properties are suspected to have a role in coral symbiont efficiency to collect light. White skeletons allow for multiple scattering of light, increasing the light field of the symbionts. In excess light, the efficiency becomes too high, resulting in dinoflagellate photosynthetic damage and sometimes, death. It is hypothesized a decrease in multiple scattering will reduce the light field within the coral tissue and decrease the symbiont light absorption efficiency.
