Morning brought with it coffee and the first-light ablutions of our crew and the birds that have made the island their home. Aside from goats, the island is also populated by a variety of birds, bats, rats and crabs. The high-tide swells sent wave upon wave of water crashing into the caves that the sea has carved out of the cliffs on the southern side. In the distance, a manta ray leaped out of the water, perhaps in celebration of the new day, or maybe just to dislodge a few bothersome parasites. It was a sign, and we prepared ourselves for the dive. And what a dive it was The current, apparently renewed by a restful night, fought us continuously in its attempts to drag us off the ledge and down to the depths. We spent most of the dive clinging to the top edge of the wall along with the rest of the critters that struggled against the flowing water. Fish everywhere, of all shapes, sizes and colours formed a rainbow multitude of quivering fins and pulsating tails, all in an attempt to stay in the same place. And then the mantas arrived. With a flick of giant wings and a twist of their diamond bodies they mocked our struggle as they hung motionless above the reef. They swam in the shallows, where the current was strongest, while white-tip reef sharks used the shadow of the giant wall to effortlessly cruise the waters below us. Exhausted after an hour of this frenetic struggle surrounded by these serene giants we let go of the reef. Blasted into deep water, quickly losing sight of the wall, we shot our marker buoys to the surface signalling to the boat crew that we were drifting away from the island into open water. When we finally reached the surface the presence of the boat was a welcome sight, and we dragged ourselves on board.
