I think not exactly? But I'm not sure. This website explains it pretty well imo: https://www.paddleasia.com/karst-topography.htm

I'm not a geologist or anything but summarizing some of the info, Coral Polyps deposited the lime that turned into limestone ~100 million years ago. Halfway down that page is a photo of how the bottoms are more narrow than the tops on some formations as the sea levels went down and carved them out

I was looking up how these rock formations were formed and found:

> The cliffs were once part of an ancient coral reef that covered most of Southeast Asia during the time when the earth’s oceans were hundreds of feet higher than they are today. Millions of years passed and cliffs remained standing, towering like magnificent rock giants.
