The farther down the evolutionary chain an oceanic critter is, the better it tastes. (Sometimes expressed as "The more eyes and fewer feet something has...")
This goes a long way towards explaining why scallops, for example, are so delish, since they have, like, a bazillion eyes and one foot.
Last night was Nice Meal Night at Roseholme Cottage. I turned my hand to some sea scallops as big as a baby's fist, bronzed in butter and white wine. RobertaX did her "popcorn asparagus". We tortured the cats by eating shellfish as big as their heads and making "Mmmm-Mm!" noises while watching MythBusters.
