Calico Scallop Dissected

Like other bivalves, the two valves, or shells, of the calico 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.

Calico 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:
Whooping cranes mate for life, but they will take a new mate after the loss of the original. The pair will return to use and defend the same nesting and wintering territory year after year.
