A bleached coral isn't dead, it's starving.

Corals live with tiny algae that give them colour and up to 90% of their food. When the water gets just 1–2 °C too warm, the corals expel the algae and turn white. They are still alive, but unfed. If the water cools soon, they take in new algae; if it stays warm, they starve.

Useful: Bleaching is an early warning, not a death sentence: how quickly the water cools decides.
