    Submerged Rock is exactly that: a large rock formation sitting just below the surface, acting as a magnet for pelagic action. We often see schooling hammerheads here, cruising in the current off the deeper walls. White-tip reef sharks are common too, sometimes resting in the crevices. This site is definitely one for experienced divers comfortable with surge and potentially strong currents, keeping an eye out for bigger fish.
