Oman: something fishy afoot

On this evening's beach walk we played a game of 'guess what animal this used to be'. The grey fuselage of a ray was bobbing around in the surf with entrails jutting out like overstuffed sausages. The wings had been cleanly removed and the tail had also been cut. This was found a few metres along the beach. The meat is considered a delicacy in some parts of the world, although I have not seen it locally. Don't want to either.
