Mario,
Looks great! I grill just about all the stuff you have, except the octopus, hard to get here in Orlando area and difficult to cook or not to over cook. Back in the day, we would go clamming up in New Jersey, and get those little "cherrystones" and open them, put a pat of butter and garlic and some cocktail sauce on them and then onto the grill. When the butter boiled, we would slurp them down! Amazing food when fresh like that!
I grill shrimp sometimes, but mostly boil. I get the big 16-20's and with the heads off, but still shelled, boil them in Old Bay Shrimp boil, bust open the bag of spices, boil them and then when done, pour out the hot water and throw a can of cheap beer in and let them steam a minute or two and then eat them hot! Cocktail sauce has to be hot, spicey hot and with fresh lemon mixed in, with the horseradish, perfect! Keep the shrimp recipe just between us, okay......
