text: Almost all the invertabrates are edible-and most are eaten by one culture or another, but lets assume you are making a menu for an American group- Common inverts that the average American would eat would include clams, scallops, lobster, crab, maybe escargot (snails), calimari (squid), shrimp, all sorts of mussels, especially in soup.\nMore exotic, but still found in Western countries would be, for example, chocolate-covered ants, sea urchin, octopus (especially in sushi).  \nIn a lot of countries, fried large grubs are eaten, worms, any sort of insect.  The one class of invert that is rarely eaten are the spiders, centipedes, millipede family, because they are often toxic or carry parasites that can infect people.
