How Can a Coral Reef Starve in Bright Sunlight?Corals depend on algae living inside them, and heat stress can force the algae out, leaving the coral pale, hungry, and at risk even in clear tropical water.
1. At noon, Maya floated above a coral reef in a clear tropical lagoon, her waterproof sketchbook pressed to her chest. She wanted to find the brightest color in the reef and draw it before the tide changed.
2. Beneath the hard white sun, she found a branching coral that was almost white. Its neighbors glowed blue, green, and orange, but this colony looked as if all its color had been rinsed away.
3. Maya pointed without touching the coral. “How can a reef fade in all this sunlight?” Dr. Imani Okafor knelt beside her in the shallows and studied the pale branches.
4. “Coral is an animal,” Dr. Imani said. “Inside its living tissue are tiny algae. They use sunlight to make food, and the coral gives them a safe home. The algae share some of that food with the coral.”
5. Maya looked at the glittering surface. Sunlight was not just a bright decoration; it powered the algae’s food-making. But Dr. Imani’s thermometer showed that the water had stayed warmer than the reef could comfortably bear.
6. When heat lingers, the coral becomes stressed. It can push its algae out, leaving the pale skeleton visible beneath the living tissue. This is coral bleaching, and the white color is a warning, not a sign that the coral is healthy.
7. Without its algae, the coral loses much of the food it usually receives. It may recover if cooler water returns and the algae come back, but a long hot spell can leave the colony hungry and weak.
8. Maya had planned to fill her page with turquoise, gold, and pink. Instead, she drew the pale branches and the warm water beside them. The reef’s truest color, she decided, was a warning she could not paint away.
9. The sea still flashed bright around her, and the water still looked clear. Yet beneath that beautiful surface, the reef needed its tiny partners: Corals depend on algae living inside them, and heat stress can force the algae out, leaving the coral pale, hungry, and at risk even in clear tropical water.
