The Suppressed Vitrinella


At about 1/10 of an inch in diameter, the Suppressed Vitrinella, Cyclostremiscus suppressus (Dall, 1889), is one the many true micromollusks found on Sanibel and Captiva. A member of the family Tornidae, it has a circular, puck-shaped shell with three distinctive keels around the shell periphery. Well-defined grooves separate the keels from each other. The Suppressed Vitrinella is usually opaque-white or slightly translucent (shells of recently dead individuals). Its Latin specific name, supressus, in this case means “pushed down” or “flattened,” an allusion to typical shell shape.
