Zooxanthellae are single-celled protozoans (dinoflagellates) that are able to live in symbiosis with certain marine invertebrates.In freshwater habitats, similar endosymbionts are known as zoochlorellae.ooxanthellae are photosynthetic organisms, and as well as chlorophyll a and chlorophyll c, contain the dinoflagellate pigments peridinin and diadinoxanthin.
