Sometimes the larger valve will have an opening near the hinge line through which the pedicle extended in life. Most species avoid locations with strong currents or waves, and typical sites include rocky overhangs, crevices and caves, steep slopes of continental shelves, and in deep ocean floors. Los braquiópodos son organismos triblásticos. They reached the peak of their diversity during the Devonian (Emsian Stage ~407-393 million years ago).
