Shell of the Week: The Intermediate Cyphoma
Cyphoma intermedium(G.B. Sowerby I, 1828) reaches about 35 mm (about 1.4 inches). The shell shape is elongate-oval, usually white when found dead, but fresh specimens have orangish shell tinges. Unlike other species in the genus found locally (the Fingerprint Cyphoma, Cyphoma signatum, and McGinty Cyphoma, Cyphoma mcgintyi), the dorsal ridge on the Intermediate Cyphoma is very weak or absent. The columellar fold is pronounced anteriorly and posteriorly. At least one shell of this species was found on Sanibel Island.
