Hermit crabs in Christmas tree worm holes, Vu Ya Passage, south of Vanua Leva, Fiji

When he found out that I was set up for 2:1, one of the photographers on the boat suggested that I try to get a picture of one of these little hermit crabs with an out-of-focus Christmas tree worm in the background.  That's not what you see here.  The reason is that I failed completely.  While I think it's a great idea, the hermit crabs seem to like the worm holes that are recessed into the boulder coral, not the ones that stick out, and it's really hard to shoot across the boulder coral and have much crab in the picture. I'll keep working at it, but I don't think I'll have enough time on target to have much chance of success.
