Shell of the Week: The Dubious Cerith

At about 4.5 mm (about 0.5 inch) in height, the Dubious Cerith, Finella dubia (d’Orbigny, 1840) is one of the small gastropod species that dwell in sea grass beds around Southwest Florida and other parts of the tropical Western Atlantic. Dubious Ceriths feed on plant and algal detritus. The shell is elongate, turret-shaped, with three or more strong spiral cords. The shell color may be cream-white to light-brown with faint spots of darker color.
