Arca zebra
The Turkey Wing is one of the easiest shells to identify, with its color and shape resembling the wing of a Wild Turkey. Also notable is the long straight hinge line that connects it to a matching shell half. Its shell is thick and can grow up to 4 inches in length. This bivalve can be found from the low tide mark down to 20 feet deep where it attaches itself to rocks or other hard surfaces with byssus (threadlike filaments).
Living animal shells are covered with a thick coating or periostracum. They are important and efficient filter feeders that filter large amounts of plankton from the water.
Thousands of tons of these clams are harvested in the Caribbean each year. In Bermuda, "Turkey Wing Pie" is a favorite.
Live shells should never be taken from any Florida State Park.
