The Wedge Piddock
The Wedge Piddock, Martesia cuneiformis (Say, 1822), is a wood borer that may be found in driftwood and floating logs in the Western Atlantic Ocean and Gulf of Mexico. The shell, which may attain ¾ inch in length, is usually pear-shaped, and very thin. Typically, Piddock clams have the anterior (wider) part of the shell equipped with rows of tiny tooth-like projections. These act as a cheese grater, enabling the clam to bore its way into the wood.
