Cave of the Sleeping Sharks

This modest cavern earned an outsized place in shark science. In the 1970s local diver Ramon Bravo and researcher Eugenie Clark documented Caribbean reef sharks lying motionless on its floor — animals long believed unable to stop swimming — apparently eased by oxygen-rich, lower-salinity water welling through the rock. Cousteau's cameras followed and the site became legend. Today the honest version matters: sharks still pass through the area, but finding one asleep in the cave is uncommon, and decades of visitation likely played a part. Dive it as a pilgrimage with a bonus chance, not a guarantee.

您此行的高光时刻: A landmark of shark-behavior history, cavern ledges, possible resting nurse or reef sharks.

地形地貌: A low limestone cavern and ledges at about 20 m where fresher groundwater seeps into the sea.

水流: Open Caribbean water; expect movement.

入水方式: Exposed site northeast of the island; dived when seas allow.

危险因素: Overhead ledge, surge, and open-sea conditions on the windward side.

保育: If a shark is resting, stay wide and low outside the cavern mouth; crowding it defeats the site's entire story.
