What are the adaptations of zooxanthellae?

Zooxanthellae are symbiotic algae that have adapted to live within the tissues of coral and other marine organisms, allowing them to perform photosynthesis and provide essential nutrients to their host. They possess specialized pigments that enable them to efficiently capture light, even in the often dimly lit depths of coral reefs. Their ability to regulate their own growth and reproduction in response to environmental conditions helps maintain the delicate balance of the coral ecosystem. Additionally, zooxanthellae can tolerate a range of temperatures and salinities, making them resilient in various marine environments.
