Sơn Đoòng cave is a living ecosystem.

 

Hidden deep in the jungles of central Vietnam lies Sơn Đoòng Cave, the largest known cave on Earth. Stretching over 9 km in length and reaching 200 meters in height, this underground giant is so massive it could fit a whole block of New York skyscrapers inside!
