Winner, Underwater, ANZANG 2009

This lake has been disconnected from the sea for almost a decade. In the absence of predation, the lake now provides the perfect habitat for thousands of pulsating Jellyfish. I dived in one afternoon and watched in amazement as light streamed through the lime-green waters onto the animated Jellyfish.
