Still image from Coral Bleaching: A Breakdown of Symbiosis

Corals get much of their energy from symbiotic algae that live inside their cells. When ocean temperatures rise beyond a certain threshold, the algae’s photosynthetic machinery may be damaged and produce harmful reactive oxygen molecules. This animation shows how corals subsequently eject their algae in a process called coral bleaching, which causes the corals to turn white and often eventually die.
