Reaching about 35 mm (about 1.4 inches) in size, Sthenorytis pernobilis (P. Fischer & Bernardi, 1857), can be found in deep water around Florida and the Gulf of Mexico. Thanks to its elegant proportions and exquisite sculpture of prominent blades, or costae, the species is an eternal favorite among shelling enthusiasts. (A large reproduction of this illustration is displayed in the In Focus exhibition at the National Shell Museum.)
