This critter "on the half-shell" shows some of the internal anatomy of a brachiopod quite well. First note the two valves or shells. All brachiopods have two shells.

Like the bryozoans, brachiopods are filter feeders which collect food particles on a ciliated organ called the lophophore. An excellent example of a brachiopod lophophore can be seen in the Recent terebratulid.
