The Transverse Ark
The Transverse Ark, Anadara transversa (Say, 1822), reaches 1.5 inches in size, and is seldom found in pairs. The species may be considered as the “ugly duckling” among the Sanibel shells: often neglected by collectors, it is the most common shell found in our beaches, according to an article published in 2012 by citizen scientist Susan Hewitt from New York, NY, in the magazine “The Festivus.”
