The Three-ridged Lucine
Measuring about 7 mm (about 0.28 inch), Cavilinga blanda (Dall, 1901) is another small local member of the family Lucinidae. The outline of its shell is oval, but skewed to one side, with the shell beak pointing in an anterior direction. The shell color is white, its surface is glossy, bearing a sculpture of regular commarginal lines. The internal lining of the valves is sometimes “delaminated,” flaking off. Not commonly found, possibly because of its small size. The shell illustrated was collected by Susan Hewitt on Blind Pass, Sanibel, in December 2014.
