The world's deepest underwater cave has been discovered in the Czech Republic by a team of explorers led by a Polish diver, Krzysztof Starnawski. A Czech-Polish expedition team funded in part by National Geographic found that the underwater cave, Hranická Propast, is 404 meters (1,325 feet) deep. Thus it is 13 meters (39 feet) deeper than Italy's Pozzo del Merro, now the world's second deepest underwater cave.
