China's Ministry of Ecology and Environment released a report on Thursday describing a blue hole in Huangyan Dao as the first known coral reef-formed blue hole identified in China. The report details its physical measurements and ecological features.

The blue hole's opening covers an area of about 1,491.7 square meters with a maximum diameter of 56.3 meters. It reaches a depth of 16.6 meters and features a funnel-shaped internal structure with a narrow bottom and distinct layers in water turbidity.

Preliminary geochronological studies indicate the blue hole formed at least 3,200 years ago. Researchers noted that the blue hole and surrounding waters support a diverse range of marine life.

The report highlights the area's ecological significance in the South China Sea.
