True.

Coral bleaching happens when coral polyps are stressed (most commonly by elevated sea temperatures, but also by changes in light, salinity, pollution, disease, or ocean acidification). Under stress the corals expel or lose their symbiotic algae (zooxanthellae) or the algae lose their pigments, causing the coral to turn white and lose a major source of nutrition.
