Among the Mollusks are some of the most well known of invertebrate sea creatures, like snails, clams, mussels, squid, and octopods.Although one might not see an obvious physical relationship between a snail and a squid, they are remarkably similar in construction.n general, mollusks have 3 body regions: a head, a visceral mass, and a foot..
