About 50 years ago, Isla Mujeres resident Carlos Garcia Castilla found a cave deep in the waters off of the island. Inside the cave he found many sharks that appeared to be sleeping. These days, divers frequently visit the cave to witness its inhabitants remain motionless for hours, then return to dry land to tell their story. The Cave of the Sleeping Sharks is approximately 65 feet below the surface. The phenomenon baffled marine biologists because sharks must be in constant motion in order to breathe, until it was discovered that the caves had an extremely high amount of oxygen and reduced salinity, and these conditions probably made it easier for the sharks to breathe without moving.
