Scientists from China and France have discovered a rare huge sinkhole, habitat to many species in south China.
The 420-metre deep doline, or sink hole, was among several discovered by scientists during an eight-day expedition that began on February 26 in Donglan county of Guangxi Zhuang Autonomous region.
Dolines found in Guangxi are normally around 250 metres deep, state-run Xinhua news agency reported.
Many species live in these dolines, including bats and snakes. Scientists also found some as-yet unidentified vertebrates and plants.
Dolines are special geological landscape formations found in karst regions, formed by repeated cave-ins of underground caves. They are common in China, Mexico and Papua New Guinea.
