Lucayan National Park encompasses one of the longest-known underwater cave systems in the world, with over six miles of caves, caverns, and tunnels charted. The cool dark recesses of the cavern provide shelter and nursery sites for migratory bats in the summer. Specially adapted to dark, underwater environments, the blind Remipedia has existed in Grand Bahama caves for millions of years prior to its discovery in the late 1970s in the Lucayan caverns. The cave system protected in this park represents an important part of both the natural and historic heritage of The Bahamas.
