World's longest underwater cave found

A pair of cave divers in Mexico's Yucatan Peninsula said March 5 they have found subterranean passages that constitute the world's longest underwater cave system.

British cave diver Steve Bogaerts says he and German Robbie Schmittner found flooded underground passages connecting two previously known cave systems — a discovery that shows how interconnected and vulnerable the Yucatan's fabled underground water system is.

Bogaerts says his dives proved a connection between the Nohoch Nah Chich caves and the Sac Actun system, which together measure 153 km in length. That connection shows that many of those seemingly isolated watering holes are part of a single larger system, he said. (AP)
