pelecypod. Any aquatic mollusk belonging to the class Pelecypoda (phylum Mollusca), which includes clams, mussels, scallops, and oysters. Pelecypods have two symmetrical calcareous shells, called right and left valves, that are joined by a hinge.

External molds may preserve external ornamentation of the shell, such as growth lines, ribs, and costae (fine ribs). Many bivalve fossils, however, are casts and molds of the internal surface of the shells, so they preserve the shape of the inside surface of the shell, which is usually smooth and lacks growth lines and ornamentation.

To elaborate on the protein content of scallops, they provide 12 grams of protein per 100 grams, which is a moderate amount. However, they are extremely high in protein per calorie. For instance, 300 grams of scallops would offer 36 grams of protein for only 207 calories ( 3 ).OTHER PELECYPOD MOLLUSKS WESLEY R.
