On a starry night, four Thai marine biologists scuba dived through shallow waters off an island in the country's south as billions of pink specks floated up from the ocean floor in a spectacle that takes place only once a year.
The pink specks were sperm and eggs released by coral. The scientists collected as many samples as possible for breeding, as they fight to save Thailand's expansive reefs from degradation driven by warming oceans and human activity. |
