They are filled with flowing water, forming an underwater river system within the cave. The roof of these caves often remains intact, resulting in a submerged cave system that can only be explored by scuba diving or other specialized techniques. These caves offer unique opportunities for scientific research and exploration, as well as stunning natural beauty. They are a type of underground river cave that can be found in locations throughout the world, often associated with karst landscapes and regions with abundant rainfall and soluble bedrock.
