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.In brachiopods, the pedicle valve, the ventral valve, is larger and projects beyond the brachial valve, the dorsal valve. This is to allow the pedicle to emerge from the pedicle opening and anchor the brachiopod to a substrate at the posterior. The bivalves also have a foot that is released through the posterior by opening the valves. monica mendezmedicinal gardens Brachiopoda (Lamp Shells) is a phylum of Animal.
