I really have to kick myself for not having watched this before. This is breathtaking and awesome, Dustin!
Loved the Blue-ringed octopus, and amazed you dared to swim so near it. I was aware of how poisonous they are, but had no clue that they were so small.
What kind of lighting do you have to bring with you on a session like this? If I remember correctly more or less all light disappears when you get under 10 m (~30 feet), and to make these creatures display all their beautiful colours I would imagine it takes a lot of light.
