More muck diving plus corals. Saw lionfish that looks like a mobile circus, stingrays, and lots more of those oddly named nudibranchs that look like many-colored jewels on the corals. Also a mimic octopus trying but not quite succeeding to blend into the seafloor, until it shot off to safety, away from all those big creatures noisily blowing bubbles and pointing cameras at it.
