The authors instead relate those effects to differences in water level driven by tides, waves and ocean currents. Their classification distinguishes horizontal, vertical and fracture-guided caves; several openings may connect beneath the surface. The paper’s Andros discussion explains why a water-filled opening should not automatically be treated as an isolated pit. It documents a folklore association and a physical mechanism, not a specimen of an unknown creature.",
