Hanging to the walls

We rest in the current, and it carries us along, as it does all unresisting objects. Behind Philippe's mask, another French dive guide's eyes are so startled-looking and magnified that I can never be sure whether I've done something very smart or very stupid. But every expression is intensified by the imposed silence, the implicit alertness of being out of one's natural element, the continual unknowingness of it all. Where we hang still is where the Black Tip and Grey Reef sharks congregate inside the well known passes of Rangiroa - Tiputa and Avaturo. Silky and Silver Tip sharks are out in the open blue water, White Tip sharks tend to hide under crevasses and caves, while the larger sharks are common in the outer lagoon. Hammerhead sharks are most time occasional visitors to the waters and it is beyond the diving range of scuba gears. For me, it is good news albeit that I wonder how I would react to one if I truly witness it.
