The Bright Lucine, Cavilinga lampra (Dall, 1901), is a bivalve mollusk that is a member of the Lucinidae Family of Lucines. The name name lampra comes from the Greek word meaning bright, shiny, or fine; all of which describe this pretty shell. The shell has a circular profile with a small, sharp, beak that has a furrow that offsets the posterior end. The exterior of the shell is sculpted with numerous, very fine, concentric ridges, and a few heavy concentric ridges. The shell is a shiny white with pink or orange tinges. The Bright Lucine Shell reach a maximum of 2.5 cm (1.0 inch) in length and 2.3 cm (0.9 inches) in height.

Bright Lucine Shells are found intertidally to depths up to 70 m (230 feet) and are found throughout the Sea of Cortez and south to Columbia, including the Revillagigedo Islands. They are not known to the west coast of the Baja Peninsula.
