Three paths of water: The water 'web' that forms the world's longest underwater cave

Mexico's Yucatán Peninsula hides Sistema Ox Bel Ha, the world's longest explored underwater cave system, stretching over 524 km. Formed by dissolving limestone, this vast network, rich in freshwater, also features sinkholes vital for wildlife. Remarkably, it holds ancient human remains, including 'Eve of Naharon', offering a glimpse into prehistoric life, yet now faces threats from development.
