Brachiopods are part of the broader group Lophophorata, alongside Bryozoa and Phoronida, with which they share the characteristic lophophores. In this feeding mechanism, water enters the lophophore from the sides of the valves, and the food particles are trapped in the ciliated tentacles of the organ. Their shells have two valves attached along a hinge, similar to clams. And they are sometimes confused with other shelled animals, like clams, because they look so much alike. Clams, or bivalves, belong to the Class Bivalvia in the Phylum Mollusca, while brachiopods belong to their own phylum, Brachiopoda. What Do Brachiopods Eat? Brachiopods are filter feeders!
