Like clams, the brachiopod lives in a shell consisting of two hinged valves, but the orientation of the shells is different. Brachiopods have valves covering the top and bottoms of the animal that are of different sizes and shapes, but the left and right sides are are symmetrical (or mirror images to each other).

Jan 21, 2023 · Bilaterians are animals that have bilateral symmetry, meaning that they can be divided into equal left and right halves. All animals are bilaterians, with the exception of a few groups of invertebrates such as sponges and cnidarians. Coeloms are lined by the lining of the mesoderm, which is located on the inside of the coelom.

Answer and Explanation: 1. The valves of a clam are the two cupped shells that form the clams hard outer covering These shells are joined by a single ligament.
