The other reason for the hole is to put a small knife in there to cut the one place where the conch is attached to the shell. You then pull the meat out, clean away the one alimentary canal and eat the meat. Mr. Mercat and I camped on the coast of Yucatán 45 years ago and conch was often what was for dinner.
Love me some conch. Nothing better the grabbing it your self. Tastes way better. 😋
Good memories you triggered in me. Thanks.
