This limestone island features beautiful underwater terrain, including a tunnel–often full of large tawny nurse sharks–which traverses the island about 20-meters down. The island is more like a series of pinnacles rather than one big rock and the soft limestone makes for crevices offering shelter for a wide variety of sea creatures. Some of the marine life you will see here include mantas, gray reef and spinner sharks, and eagle rays in the open water next to the island, while leopard sharks and spotted rays lie on the bottom. On and around the rocks, spiny lobster, cowrie shells, feather stars, anemones and an assortment of crabs abound. Reef fish include blue-ringed angelfish, moray-eels, snappers, frogfish, and ghost pipefish.
