Shell of the Week: The Coffee Bean Trivia

Pusula pediculus (Linnaeus, 1758) measures up to 22 mm (about 0.87 inch). The shell outline in trivias is elliptical, with an etched furrow along dorsal middle line. Trivias resemble cowries, but the sculpture of strong radial ridges sets them apart. The Coffee Bean Trivia usually lives on coral rocks in association with tunicates (e.g., sea pork.), and the species is not found along the shores of Southwest Florida.
