Topography and Marine Life
The underwater landscape consists of large granite boulders, rocky ledges, sandy patches, and coral-covered reef slopes. Massive granite formations create small swim-throughs, overhangs, and sheltered areas that attract numerous reef species. Hard and soft corals, sponges, and sea fans provide habitat for an abundance of marine life.
Divers commonly encounter schools of fusiliers, yellowtail barracuda, bluefin trevally, batfish, rabbitfish, and snapper. Butterflyfish, angelfish, parrotfish, triggerfish, and pufferfish are regularly seen among the corals, while moray eels, blue-spotted stingrays, and octopuses often hide between the rocks. Macro enthusiasts can discover nudibranchs, shrimps, and colourful reef invertebrates. Green turtles occasionally visit the bay, and during periods of good visibility, larger pelagic fish may pass by the deeper sections of the reef.
