The One-banded Wentletrap
The One-banded Wentletrap, Epitonium unifasciatum (G.B. Sowerby II, 1844), is one of the less common among the 9 species of wentletraps (family Epitoniidae) found on Sanibel-Captiva. Its shell rarely surpasses 13 mm (about 0.5 inch), and is festooned with 7–10 costae (“ribs”) that are joined from one whorl to the next. The species name alludes to the narrow, light-brown band present below the suture. The shell in the photos is a juvenile, lacking a well-defined brown band. It
