What is a brachiopod.
Brachiopods are marine invertebrates with two unequal shell halves, a lophophore feeding organ, and a pedicle stalk. They have been around since the Cambrian and were among the first animal groups to diversify on Earth. Learn about their classification, paleoecology, fossil record, and features of their shells and lophophores.
