A green sea turtle nesting site was recently spotted for the first time on a reef in the Nansha Islands in the South China Sea, according to sources from an ecological and environmental research station under the South China Sea Institute of Oceanology, Chinese Academy of Sciences.

The discovery was a result of routine ecological environment monitoring supported by the institute's island and reef research center.

During the monitoring, researchers found a roughly 30-centimeter deep, irregularly circular depression on the sandy beach area of Yongshu Reef, part of the Nansha Islands, with scattered overturned sand grains around it.
