Zooxanthellae


The zooxanthellae are the algae that live within the tissues of most scleractinians.  These organisms, a type of dinoflagellate, provide their host with food, while gaining shelter and waste products from the coral.  The photosynthetic pigments within the algae provide the coral with its colouration.  Where corals have low concentrations of zooxanthellae, they look pale and are said to be bleached.

Zooxanthellae are the algae that live within the tissues of reef building corals.
