There are still a lot of questions about how exactly dolphins execute a good conch. Researchers have seen the end result at the surface, but are curious as to how the behavior unfolds underwater. Do the dolphins manipulate the shells to scoop the fish in, or do they turn them so the opening is facing up and then chase fish into them? If the latter, it suggests a good deal of foresight and premeditation on the part of the dolphins--yet another tantalizing finding for biologists and behaviorists.
