A shallow reef slopes to between 33ft and 65 ft and then drops off as a wall to deeper than sports divers can go. The slope is very rich, with stony whip and leathery corals on sand, teeming with small reef fish and several Guitar Sharks. There are sightings of leopard (variegated) Shark here.
Huge gorgonian sea fans, barrel sponges (covered in Alabaster Sea Cucumbers) and Dendronephthya soft tree corals cover the wall together with shoals of most of the local reef fish. Among the angelfish are sixbanded angelfish and semicircle angelfish. There are schools of snappers, unicornfish, jacks, trevallies, barracuda and fusiliers.
