Brachiopods are a distinct phylum of organisms, containing …Brachiopods are an ancient group of organisms, at least 600 million years old. They might just look like clams, but they are not even closely related. Instead of being horizontally symmetrical along their hinge, like clams and other bivalves, they are vertically symmetrical, cut down the middle of their shell. While they may all look the same ...Clam. Clam is a common name for several kinds of bivalve molluscs. The word is often applied only to those that are edible and live as infauna, spending most of their lives halfway buried in the sand of the seafloor or riverbeds. Clams have two shells of equal size connected by two adductor muscles and have a powerful burrowing foot. [1]
