Some more photos:
Heron Island, not a bad place to do research work eh?
The reef flat on Heron, good for inspecting the corals at low tide, or for a snorkel at high.

Yup, someone is hungry. (and so is his entourage!)
Bluey being dark and mysterious.
And a movie of a surface feeding mega school of chromis on the reef.
