Just got back from a dive trip to the Similan Islands in Thailand. Here's a few that I sorted out. More when I get caught up on things.
The Squid that ate Cleveland

What's for lunch?

Taking a break from swimming

Another one for Halloween

The C4040 is actually fairly good at macro if used properly. The next two were taken without any external lenses.
Hanging out

Here's looking at you

I know tallent when I see it...
Well done Herb, these are nice - Especially like the P. Crab feeding, and the overall focus on the gorgonian/lionfish is nice too.
Very impressive shots!
Apparently I need to add Thailand to my never ending list of places to go.
Beautiful!! Particularly like the shot of the lionfish.
As others said before me, great shots.
My favor also is the Lionfish, one of the fishes I like most in the water.
