Can someone identify this creature for me? The picture was taking in BVI on the Rhone.

Not a scallop! It's a rough file clam (Lima scabra).

oh good call... Lima scabra is my candidate too, but the internal folds were throwing me off. we call them rough file shells. Lima pellucida (antillean file shell) is also a candidate....
how deep were you, plr0?

Clams tend to follow veneroid body plans and possess isomyarian (same-sized) adductor muscles. Scallops prefer the pteriomorph plan with unequal (anisomyarian) or single (monomyarian) adductor muscle(s).
Thing in the photo looks like a pteriomorph with monomyarian attributes (i.e. scallop). I'd go with something in the genus Lima too. Common names aren't very informative. In the case of Lima scabra for instance, it's commonly referred to as both a flame shell, flame scallop, or rough file clam. Neither is more accurate than the other.
"Internal folds"... you mean the mantle tissues? Those aren't of any use in identifying the critter, unless you have massive knowledge of it's internal anatomy. Few things are as amorphous as a bivalve's internal tissues.

ah no... i think he is agreeing with me
aren't YOU, archman????
(the thing about the folds is that at first i thought i was looking at several creatures,l
not one... i even thought it might have been the rear end of a tubeworm of some sort)
