Dinoflagellates are photosynthetic endosymbionts that form a mutualistic relationship with coral polyps to form coral. In the case of coral bleaching, the dinoflagellate component of coral dies or escapes due to changing environmental conditions, causing the coral to turn white. During harmful red tides, dinoflagellates bloom in wave, releasing toxins that damages marine and coastal wildlife.
