Darwin

Another three hammerhead dives at Darwin's arch. During the second dive, I actually get to glimpse a huge school, there must be hundreds of them, way out in the blue, barely visible, but whow, what a sensation!

Hovering in the blue, one moment I'm surrounded by thousands of small fish and a gang of jacks, then, suddenly, in a split-second, they're all gone. Below, a dolphin shoots by. Clearly in hunting-mode. Then, out of nowhere, they're all back, as if nothing had happened. Incredible.

As we finish our third dive, we end up beside a school of steel pompanos, hanging around just below the surface.
