Bay Scallop Dissected

Bay Scallop Dissected

Like other bivalves, the two valves, or shells, of the bay scallop are secreted by the thin tissue called the mantle. These valves are joined at the hinge by a ligament, and connected by a cylindrical muscle. By contracting this muscle, the scallop can open and close the two shells.

Bay scallops are hermaphroditic organisms with both male and female reproductive organs. In the image above the "ripe" gonad contains the orange eggs and white sperm.

FWC Facts:
A shrimp escapes predators by quickly pulling its abdomen in toward its carapace (body). This motion shoots it through the water backward.
