Buttercup Lucine

The Buttercup Lucine
Anodontia alba (Link, 1807)
Family Lucinidae

Buttercup Lucines are a common shell on the S. Hutchinson Island beaches. Unfortunately the beak area is frequently damged as the shell is usually not thick. The yellow/orange found on the inside is not present on my shells many of which are badly worn.

The Buttercup Lucine

The Buttercup Lucine, Anodontia alba Link, 1807 is a local clam belonging to the diverse family Lucinidae. Its shell may reach about 50 mm (about 2 inches) in length, and is circular, inflated, with many fine, commarginal (concentric) growth lines. The color is mostly dull-white, and the internal surface of the shell valves is bright-yellow to orange. Lucinids are mostly filter-feeders that also host symbiotic bacteria in their gills, which provide them with an additional source of food. The Buttercup Lucine is no exception to that.
