What are adaptations of zooxanthellae?

Zooxanthellae are symbiotic dinoflagellates that have adapted to live within the tissues of coral and other marine organisms. They possess specialized pigments that allow them to efficiently capture sunlight for photosynthesis, which provides energy to both the zooxanthellae and their host. Additionally, they have developed mechanisms to tolerate the varying conditions of their host environment, such as changes in temperature and light availability, enabling them to thrive in diverse marine ecosystems. Their ability to convert carbon dioxide and nutrients into organic compounds also contributes to the overall health of coral reefs.
