underwater caves
Flooded geological chambers
Underwater caves are natural cavities in rock formations that are partially or completely submerged in water, found beneath oceans, lakes, rivers, or within flooded cave systems.
They form through geological processes like the dissolution of limestone or volcanic activity.
Exploring them requires specialized diving equipment and training, as divers navigate tight passages and zero-visibility conditions.
The cenotes of Mexico's Yucatan Peninsula connect to an extensive network of underwater caves.
