For an attempt at scale, that tiny island of mud with the plant growing out of it is also visible as a black dot near the bottom middle of the picture on the right.
In coastal Georgia, we eat these things in regular outdoorsy parties called Oyster Roasts. First we shovel them onto a low metal table over a bonfire, cover them with burlap, and hose water on them to keep them wet while they're roasting. Then we shovel them onto high wooden tables (high, because we eat standing up) which are outfitted with oyster knives, shrimp cocktail sauce (red, tomato-based, halfway between salsa and tomato ketchup and nothing like either one), and lots and lots of paper towels. If we're being upscale, there's a big hole in the middle of the table with a trash can underneath. It's sandy and sticky and lots of fun.
