They are still alive today. On the inside surface of some, muscle scars (Figure 4C) or the support structure for the lophophore may be found (Figure 4E). Most brachiopods live in relatively shallow marine water, up to about 650 feet (200 m), but some species have been found at depths of more than a mile. This changed after the mass extinction at the end Fossil brachiopods generally fall within this same range, though some adults have shells that are less than 0.
