Green sea turtle, Chelonia mydas

While snorkelling in the lagoon late one afternoon I crossed paths with this endangered green sea turtle. I took this photo using a slow shutter speed to capture the movement of the wind-swept ocean surface and contrast with the calm below as the turtle gracefully and effortlessly glided along.
