When I used to be a fisherman we used to cook the shrimps and prawns on board. Occasionally a whiting (a fish similar to a small cod) would find its way into the cooking pot too, and find itself boiled. Once boiled, the flesh of any fish would disintegrate in the washing riddle, leaving pretty much just the skeleton. What used to get left behind too, was the fishes stomach. Having been boiled it would go rubbery, and these stomachs would eventually find themselves in a bag with the shrimps.
Oh, yer, the relevence to this thread???
Occasionally these rubbery boiled stomachs would still contain a partially digested shrimp that the fish had dined on, the gastric juices having disolved the shrimps carapace.
I don't think there's any name for these shrimps wrapped in boiled fish stomachs, but they are really nice. For some reason, no one else seems willing to try them.
